»SAINT NICOLAS« 

Abeking secures retrofit order for Lürssen yacht 

The »Saint Nicolas« on its way to the Abeking & Rasmussen shipyard 

The Abeking & Rasmussen (A&R) shipyard is to comprehensively 

overhaul the super yacht »Saint Nicolas«. The refit 

work in Lemwerder will take eight months. The 70-metre motor 

© A&R 

yacht, built in 2007, is being commissioned by A&R Services – 

the shipyard’s retrofit division. According to the shipyard, the 

plans include an extension of the bathing platform and the installation 

of a new fitness room and a spa on the sun deck as part of a 

comprehensive refit. 

The project is being managed by Arrow Yachts (Monaco). The 

aim is to remodel both the exterior and the interior of the yacht in 

collaboration with renowned design studios. Pascoli International, 

Patrick Knowles Design and Murray & Associates are 

involved. 

»This refit project represents a significant milestone for A&R 

Services,« says Daniel Reichwald, Managing Director of this business 

unit. »Our team is committed to delivering exceptional work 

and exceeding the owner‘s expectations,« Reichwald continues. 

The refit project is expected to take eight months. 

A&R Services is a provider of refit and repair services for 

yachts, founded by the traditional shipyard in Lemwerder on the 

Weser. The »Saint Nicolas« was built in 2007 at the neighbouring 

Lürssen shipyard to a design by the well-known designer Espen 

Øino. With a width of 13 metres, she is one of the most voluminous 

ships of her size and has six decks. She reaches a speed 

of 15.5 knots. 

 

PALMA INTERNATIONAL BOAT SHOW 

Mallorca becomes an industry hotspot 

The next edition of the Palma International 

Boat Show will take place from 

25th to 28th April 2024 in Palma’s Moll 

Vell, and will once again inaugurate the 

Mediterranean nautical season. The show 

is organised by the Institute for Business 

Innovation of the Balearic Islands (IDI), 

an entity dependent on the Regional 

Ministry of Enterprise, Employment and 

Energy, and the Balearic Yacht Brokers 

Association (BYBA). 

The event has a very complete offer including 

everything from all kinds of new 

boats to nautical products and equipment, 

as well as services, and marinas. 

Due to the organizers, a special mention 

should be made of the Palma Superyacht 

Village, a section specially designed for 

boats over 24 metres in length, both sailing 

and motorboats, and which also includes 

an area specialising in boat repair 

and maintenance, known as refit & repair, 

in which the leading companies in 

the nautical industry take part. 

The Palma International Boat Show has 

established itself as one of the essential 

fairs at the start of the nautical season. 

This is borne out by the participation figures 

of recent editions. In 2023, the fair 

had 271 participating companies and 

some 600 boats on display, more than 250 

at sea, spread over an 81,000-squaremetre 

exhibition site. It was also the setting 

for the presentation of new boat models 

and products on a global scale, as well 

as becoming the nerve centre of the sector 

for four days. The last edition was characterised 

by a very full agenda of events, 

During the last show 600 boats were exhibited 

such as activities to promote training and 

employment in the nautical sector. In addition, 

the Palma Superyacht Village area 

hosted the Innovation Corner, a space 

dedicated to emerging companies focused 

on innovation in the nautical world, especially 

with digitalisation and sustainability 

solutions.

SPOTLIGHT ON ... 

German shipyards triumph 

at the »Yacht Oscars« 

The International Superyacht Society (ISS) Awards are 

regarded as the Oscars of the yachting industry. They 

are presented annually during the Fort Lauderdale International 

Boat Show; the winners are chosen by an independent 

jury of industry representatives. At the Ritz Carlton 

in the American coastal town, the current ceremony 

turned into a showdown for two German shipyards. 

In the »Best in Motor 1,500


hard work of our team.« Kleymann had to orchestrate 

the final phase of completion during the height of the 

coronavirus pandemic and organize the final outfitting 

in shifts. »Soaring« or »Starlust« has an impressive library, 

a bar with an integrated whirlpool and a beach 

club with an integrated spa. 

Just a few hundred metres away from Abeking & Rasmussen, 

Lürssen was able to celebrate three ISS Awards. 

The 115-metre-long »Apho« won the categories »Yacht 

of the year«, »Best Interior Motor« and »Best in Motor 

5,000+ GT«. Nuvolari-Lenard designed »Apho« for a 

customer who has been loyal to the shipyard for many 

years. 

The crew of the 93-metre-long »Mayan Queen«, 

which was also built in Germany (by Blohm + Voss), received 

the »Distinguished Crew Award«. Their rescue of 

over 100 migrants whose boat had been wrecked was 

recognized by the audience with standing ovations.

Fuel cell laboratory opened 

Last but not least is the Innovation Laboratory that has been up 

and running at Lürssen since last year, where the shipyard is 

simulating and testing the integration and operation of a Marine 

Hybrid Fuel Cell System on board a yacht powered by methanol. 

The testing is being conducted under real life ambient conditions 

and with all required auxiliary systems. This demonstration plant 

can be considered the final preparation to bring fuel cells on 

board a yacht successfully. The delivery and integration of their 

first fuel cell system is scheduled for the middle of 2024 for project 

»Cosmos«. The design phase has been completed and 

Lürssen is the first shipyard to receive the necessary certificates 

from Lloyd’s Register, for the integration of the Methanol-powered 

fuel cell and the related shipboard systems in June 2023. »Cosmos« 

was launched in March 2023 and the outfitting phase is 

now in full progress.

After a building break »REV Ocean« will leave her shipyard with a 12 metre extension. Her LOA will be nearly 195 metre 

acquired the 71-metre »Skat« from Charles Simonyi. A vessel in 

his possession for two decades, constructed by Lürssen and designed 

by Espen Øino – mirroring the design team of »REV 

Ocean«. Simonyi later replaced »Skat« with the 20-metre »Norn«, 

maintaining continuity with the same shipyard and designer. 

While construction on »REV Ocean« experienced a pause in 

2021, the shipyard has confirmed the preservation of the vessel‘s 

original vision with plans to enhance its functionality. This includes 

a midship extension of 12 metres, elongating the existing 

hull for increased buoyancy and incorporating lightweight materials 

to replace some of the steel. The vessel will feature a reorganized 

layout, providing more space and heightened scientific 

capacity in its primary hangar. 

Kjell Inge Røkke‘s vision for »REV Ocean« transcends a conventional 

superyacht, positioning it as a platform for knowledge 

acquisition. Welcoming researchers, environmental groups, and 

institutions on board, Røkke envisions the vessel as a hub for developing 

innovative solutions to address challenges and opportunities 

related to the seas. 

Despite its collaboration with leading superyacht designer 

Espen Øino, »REV Ocean« won‘t be classified as a traditional 

superyacht. Focused on advanced oceanography, the vessel will 

be equipped with state-of-the-art equipment to survey marine 

environments comprehensively. The extension will facilitate a 

dedicated submarine hangar, a HiPAP system for subsea equipment 

tracking, an additional science lab, and facilities for 3D 

printing and onboard metalwork. In alignment with environmental 

consciousness, »REV Ocean« is designed for optimal fuel 

efficiency, featuring an energy recovery rudder system, mediumspeed 

engines, a direct-drive diesel-electric propulsion system, 

and an exhaust cleaning system. The increase in size, though 

leading to a 32% rise in fuel capacity and range, is anticipated to 

have a relatively minor impact on fuel consumption. 

Upon delivery, »REV Ocean« will be available for charter, with 

plans for its maiden voyage involving a journey from the Arctic 

via the Norwegian coast, followed by a route through the United 

States and South America to reach the Southern Ocean. 

The expected delivery by VARD is set for February 2025, with 

operational readiness projected for Q4 2026. VARD will undertake 

the rebuild at its facilities in Norway, and final completion 

activities will occur at a location to be determined closer to delivery.

What‘s coming in 2024? 

The deliveries of numerous superyacht projects 

in the 80-to-120-metre range have been announced for this year. HANSA Yachts 

takes a look at some of the most interesting projects 

© Feadship 

Feadship 825 

The 76-metre project 825 from the Dutch 

shipyard Feadship was launched in 2022. 

The exterior design and construction 

were created by De Voogt Naval Architects, 

while the interior was designed by 

Gilles & Boissier. Project 825 has an exceptionally 

large aft deck with an infinity 

pool and can accommodate up to 12 passengers 

and a crew of 17. The bridge deck 

offers a spa area with sauna, massage 

room and gym. With two 2,000 hp MTU 

engines, the Feadship yacht has a cruising 

speed of 12 knots and a top speed of 15.4 

knots. She is scheduled to leave the shipyard 

in November. 

Freire 105 Explorer 

The Spanish shipyard Freire announced 

the construction of a 105-metre-long explorer 

yacht in 2021, the keel of which was 

laid a year later and which is due to be 

launched in 2024. Little is yet known 

about the project all that is known is that 

the Freire 105 Explorer will have a volume 

of around 4,000 GT and a very efficient 

hull. Once completed, the superyacht will 

be the third largest vessel in the shipyard‘s 

portfolio. Two other Freire yachts are already 

underway with their owners.

Project 825 from Feadship is for sale. Burgess is listing the vessel for 169 million Euro 

Turquoise »Toro« 

»Toro« is a 79-metre-long project by Turquoise 

from Tuzla, Turkey. Harrison 

Eidsgaard is responsible for the interior 

and exterior design, while the construction 

is by Turquoise itself. The neoclassical 

exterior of the yacht is complemented 

by a serene and calm interior. 

The special features of »Toro« include an 

underwater lounge. With a volume of 

2,050 GT, the yacht has a capacity for 14 

guests and 21 crew members. 

Turquoise »Vento« 

The 87-metre »Vento«, whose exterior 

was designed by H2 Yacht Design, is also 

being built by Turquoise in Turkey. As the 

longest yacht built by Turquoise, it will be 

the shipyard‘s flagship when completed. 

Onboard amenities include a 6.5-metre 

infinity pool, a touch-and-go helipad and 

a huge bow area that functions as a basketball 

court or a large sun deck with outdoor 

cinema 

Lürssen »Ace 21« 

A 78-metre motor yacht with the project 

name »Ace 21« is currently being fitted 

out at the German Lürssen shipyard after 

the hull was built at Stahlbau Nord in 

Bremerhaven. Further details are not yet 

known, except that the yacht will as usual 

be powered by two diesel engines and 

have a volume of 2,500 GT. The ship‘s 

architecture was designed by Lürssen 

itself. 

Feadship 712 

Feadship‘s second current project for 

2024, Project 712, measures 82.90 metres 

in length and has an exterior design by 

Sinot Yacht Architecture & Design, while 

the structural calculations are by De 

Voogt Naval Architects. The yacht has a 

volume of around 2,000 GT and stands 

out with its straight bow and clear exterior 

lines. Future guests will have plenty 

of space for sunbathing and al-fresco 

dining on the three stepped aft decks. 

Yachtley N91 

The Yachtley shipyard, based in Turkey, is 

currently working on a 91-metre project 

called N91. The project is the shipyard‘s 

largest to date. The exterior design and 

naval architecture are by Alpha Marine 

Ltd Yacht Designers & Naval Architects. 

The design studio had already designed 

the superyacht 80-metre »Elements« in 

2019, which was also built by Yachtley. 

Damen Custom Hybrid 75 

The 75-metre Custom Hybrid 75 explorer 

yacht, which is currently being 

built by Damen Yachts, also comes from 

Dutch production. The shipyard itself 

contributed the ship‘s architecture, while 

the exterior design was created by Michael 

Leach Design. The Custom Hybrid 

75 was conceived as a milestone in the explorer 

yacht segment and features a hybrid 

propulsion system designed to enable 

emission-free travel. It can accommodate 

up to 12 guests.

INTERVIEW | DERECKTOR SHIPYARD 

From a small shop 

to a refit giant 

Derecktor is one of the best-known 

shipyards in the USA. The refit specialists 

with four locations on the east coast are 

now also pushing into the European 

market. Joel Shine, Chief Commercial 

Officer, and John Koenig, Chief Marketing 

and Sales Officer, provide insights into 

the set-up 

Derecktor is one of the best-known names in the American yacht 

industry in particular. Could you perhaps briefly outline the beginnings 

of the shipyard for our European readers? 

John Koenig: In 1947, shortly after returning from serving in the 

Pacific for the US Navy, Bob Derecktor followed his dream of 

building boats. He opened a small shop just outside New York 

City on Long Island Sound with a small handful of craftsmen and 

started the journey to create what today is Derecktor Shipyards. 

At first, the yard built small wooden sailboats and launches for 

local customers. Quickly the business grew to building power 

boats, commercial craft and larger sailboats for an expanding 

customer base. In the early 1960s, the yard became a pioneer in 

lightweight construction, a skill it has near perfected over the 

years. This led to larger boats of more variety – and eventually to 

the Derecktor of today. 

How has the business developed since those early days? 

Joel Shine: In the mid 1960s, Bob Derecktor realized that South 

Florida was an emerging yachting market. Acquiring land on the 

Dania Cut-Off Canal adjacent to Ft. Lauderdale, he began the development 

of what is now Derecktor Florida. The need for expert 

service and repair kept the yard busy and growing, and it established 

itself as one of the forces that made Ft. Lauderdale »The 

Yachting Capitol of the World«. 

Today, the yard features a 900-ton Cimolai hoist, a protected 

(hurricane hole) basin and the expert work and service Derecktor 

is known for. In New York, Derecktor kept building, launching 

innovative vessels ranging from the Americas Cup Winner Stars 

& Stripes ‘87, to the world’s fastest passenger ferry, to Cakewalk, 

the largest yacht ever built in the U.S. (which was launched in 

Connecticut in 2011). Today the NY yard continues leading the 

way in new construction with a series of hybrid electric commercial 

catamarans. 

In Florida, the 2020 establishment of Derecktor Fort Pierce 

(DFP), just north of Palm Beach, opened new markets to Derecktor 

as well as to the U.S. industry as a whole. On the site of an historic 

port, the new yard offers (9m controlling depth) direct access 

from the Atlantic with no bridges, quayside space for 100 

metres plus vessels and the largest yacht mobile lift in the world – 

a 1.500-ton Cimolai Hoist. Deep-draft sailing yachts and very 

large motor vessels now a have a convenient choice of yard close 

to the huge variety of skilled subcontractors in South Florida. 

When we talk about the current Derecktor line-up. What key figures 

can you give us? How is the business divided between the 

four locations? 

Shine: New York continues to be the primary new construction 

yard, with its proximity to the New York commercial market and 

77 years of vessel building expertise. The yard also does substantial 

amounts of repair and refit work for the NY fleet of ferries, 

pilot boats and other craft, as well as the yacht market on Long Island 

Sound. 

Maine is a marina and boat yard in a beautiful cove about 45 

minutes by car from Portland. It offers dockage for boats up to 30 

metres, along with hauling, service and winter storage. It also features 

houseboat rentals and an excellent onsite pub and restaurant. 

The Florida yards in Dania (Ft. Lauderdale) and Ft. Pierce are 

primarily engaged in the repair, refit, and storage of large yachts 


DERECKTOR SHIPYARD | INTERVIEW 

© Derecktor Shipyard 

Derecktor‘s shipyard in Fort Pierce has one of the highest capacity mobile hoists in the world 

and super yachts, with Dania handling vessels up to approximately 

65 metres and 9.00 tons, and Ft. Pierce vessels to 100 

metres plus and 1.500 tons. 

The capacity of Fort Pierce sounds enormous. Is there anything 

comparable in the USA or even in Europe? 

Koenig: Derecktor Fort Pierce has one of the highest capacity mobile 

boat hoists in the world, a Cimolai machine rated at 1.500 short tons. 

Our future development plans include a floating drydock to further 

increase our capabilities to service vessels over 1.500 tons. 

Which customers are you focusing on for Fort Pierce? Is it about 

minimum lengths or minimum stays? 

Shine: There are no minimums per se; we have hauled nearly 

every type of vessel from 15 metres to 73 metres, with work 

scopes ranging from dockside services and FTZ dockage all the 

way to full refit and large paint jobs. 

European owners often stop at refit yards in the Mediterranean 

before or after the Caribbean season. How can Derecktor »take a 

slice« of this cake? 

Koenig: A deep-water inlet, no air draft restrictions, and pier 

make Fort Pierce one of the few places on the entire east coast 

of US and the Caribbean that can handle multiple 60+ metre 

motor yachts, and we are the only shipyard in the region that 

can accommodate very large sailing yachts. 

Proximity to Fort Lauderdale enables us to access, services, and 

materials from the heart of the super yacht industry on this side 

of the Atlantic. Virtually any task achievable in Fort Lauderdale 

can seamlessly be brought to Fort Pierce.

INTERVIEW | DERECKTOR SHIPYARD 



John Koenig 

Joel Shine 

What services do you offer in Fort Pierce? Which yachts have 

already been on site? 

Koenig: Without giving names; We are a full-service shipyard, 

having hauled yacht up to 1.320 tons. Additionally, we have provided 

dockside refit services for yachts up to 117 metres. Our 

range of services includes everything from simple bottom jobs to 

full refits, facilitated through our in-house trades and a network 

of over 120 contractors. 

How do you argue against reservations about hurricane risk in 

Florida? 

Shine: Hurricanes are a risk, but mainly an insurance issue. Derecktor 

has lived with hurricanes for 50+ years in Florida. Tropical 

cyclones and intense weather are something we are accustomed 

to mitigating and living with. Last year, we had a 73 

metres on the hard while a hurricane passed directly over Fort 

Pierce with no accident or damage. If an insurance carrier for 

one of our customers requires an extra premium to be here in 

hurricane season, we are willing to help cover that expense. 

For crews, the refit base is sometimes crucial. What can Fort 

Pierce offer? 

Koenig: Fort Pierce offers a more relaxed »Old Florida« vibe, a welcome 

change for many captains and crews tired of the busyness in 

Fort Lauderdale. Despite the laid-back atmosphere, the downtown 

area still offers plenty of activities. Great restaurants and bars are

YACHT EQUIPMENT | ENERGY AND STORAGE SYSTEMS 

developing and polishing this platform, ABB firmly believes that 

DC will be part of Shipping 4.0. 

Due to fast high voltage energy transmission, naval architects 

may now design complex systems with several battery rooms 

scattered across the hull to optimize weight distribution. This 

permits one to install light and compact drives without overweighting 

the aft. In addition, it gives designers more freedom 

in terms of utilizing the space for beach clubs and other guest 

areas. 

Traditional shaft drives are still the number one choice for 

most large hybrid yachts. Shafts are usually coupled with 

liquid-cooled permanent magnet propulsion motors. There are 

several ways to increase total efficiency, and multiple companies 

offer their know-how. For instance, Baltic Yachts and 

Bering Yachts have chosen Danfoss Editron as a supplier of key 

elements for propulsion systems on their hybrid Baltic 110 and 

Bering 145 respectively. Southern Wind teamed up with BAE 

Systems which equipped SW96 Nyumba and SW108 Gelliceaux 

with state-of-the-art HybriGen diesel electric propulsion 

system with DC Link (650 V) providing substantial fuel savings. 

This list can go on and on since the market niche of hybrid 

and electric propulsion is well populated with more and more 

players from commercial and offshore segments offering their 

solutions to yacht builders. 

The compact, air-cooled Cube system from Lehmann aims vessels 

with limited technical space 

scalable to several megawatt hours and use LFP cells that are not 

prone to fire in case of thermal runaway event. 

MG Energy Systems caters leisure and commercial markets, offering 

batteries, BMSs, and ESS for various needs. Their new RS 

230 liquid-cooled module with integrated exhaust system features 

third generation LiFePO4 cells with a total nominal energy 

of 11,8 kWh (51 V) and allows stacking in high-voltage strings up 

(to 900 V). The company is going to start sales in the second half 

of 2024 when RS 230 receives DNV approval. 

ESS is much more than just adding a battery pack on board. As 

a key element of the ship power system, it provides not only storage, 

peak shaving, and spinning reserve but also seamless automatic 

energy flows between producing and consuming equipment. 

There are two main architectures of electrical systems on 

modern vessels: AC distribution network with DC links and DC 

grid and. Depending on selected batteries setup, the output voltage 

varies in the range of 700–1100 V. With recent advancements 

in DC fault protection methods and increase in overall grid 

safety, the latter architecture has started to be seen on yachts. 

One of the notable examples is »Artefact« (Nobiskrug, 80m), 

where ABB integrated electric Azipod drives with Corvus Orca 

ESS (610 kWh) and Caterpillar 3516 generators through their 

highly customizable Onboard DC Grid. After over a decade of 

© Lehmann Marine 

Ten years of R&D work 

Among the recent additions to electric drives one could mention 

ABB Dynafin, the modern reincarnations of almost century old 

Voith Schneider propeller (VSP). ABB engineers claim unprecedented 

efficiency increase that they have managed to achieve 

after ten years of R&D work. In many ways Dynafin is similar to 

eVSP, introduced by Voith in 2020; however, it features significant 

improvements of cyclorotor design. ABB optimized the shape of 

the vertical blades and used electric motors to instantly control 

them. The ECUs individually tune the angle of attack for each 

blade and can change their motion path in every cycle if needed. 

Basically, Dynafin is a smart VSP with stated efficiency of 85% in 

undisturbed flow. It benefits from lower noise and vibration levels 

compared to shaft drives due to lack of any mechanical gear 

assemblies and relatively low-pressure pulsation. According to 

ABB, the modular design of Dynafin guarantees unobstructed 

access to all components for easy maintenance and fast repairs. 

The prototype is expected to be available in 2025. Once ABB establish 

production line it is going to introduce several models in 

the range of 1–4MW aimed at small to medium size vessels including 

yachts. 

In general, electric propulsion systems, fuel cells, and batteries 

are taking a leap forward in the whole maritime industry. The 

next awaited improvements include switching from liquid to 

solid electrolytes, which would increase energy density of batteries, 

as well as the wide spread of methanol fuel cells. Moreover, 

ongoing digitalization of power grids leads to implementing 

promising energy exchange concepts where battery equipped vehicles 

and vessels are seen not only as recipients but also as donors. 

At the same time suppliers still spend considerable time and 

effort to achieve type approval status for their products, especially 

for those containing large high-capacity batteries. This slows 

down incremental improvement aligned with model years, so the 

evolution of marine ESS lags somewhat behind. But it will catch 

up thanks to strong tailwinds.

YACHT EQUIPMENT | MOTION CONTROL SYSTEMS 

Stop the motion 

Modern yachts and superyachts have high tech, powerful stabilizers that reduce up to 90% 

of the roll from waves and weather. They are complex, and can be expensive, but they 

make sense for lots of yachts 

The science of ship motion is well developed 

and deals mostly with two 

key parameters: the shape and dimensions 

of the hull. Today engineers possess 

a variety of tools such as 2D strip theory 

to numerically estimate and predict motion 

with rather quick calculations. As a 

result, academic research often translates 

into applied characteristics, such as the 

yacht comfort index developed by Feadship 

and Marin. 

There are numerous motion control 

systems around. They range from passive 

keels, fixed fins, and anti-roll tanks to 

sophisticated moving appendages or 

gyroscopic devices operated by computers. 

Effective first-order ship motions 

damping is paramount in case of large 

luxury motor yachts, since their passengers 

always seek uncompromised comfort 

without any motion nuisance. This is 

especially important for charter vessels, 

where zero-speed stabilization is a must. 

Active fins remain the main choice for 

yachts over 30m with relatively slender 

hulls and narrow waterline beam. Depending 

on length, one or two pairs are 

usually installed to reduce roll while 

underway and on anchor. There is no 

universal »one-size-fits-all« solution. To 

figure out optimum fin size and shape 

naval architects consider various parameters, 

such as displacement, roll period, 

windage, and wight distribution on 

early design stage. It is important to know

that roll motion damping systems normally 

deliver no more than 45% of critical 

damping value due to possible integration 

issues. 

Numerous manufacturers offer a broad 

range of systems with various space 

requirements and cost. Historically, fin 

stabilizers with hydraulic actuators dominated 

the market; however, the balance 

has significantly shifted towards electrically 

driven models over past decade. 

Alessandro Capiello, engineer and 

founder of CMC Marine, is purposely 

working up this niche. He does not like 

noisy and power-hungry hydraulic fins 

with their short motion range. According 

to Capiello, electric stabilizers are lighter 

and quieter (

ship models that are meant for displacement 

and semi-displacement hulls. 

The compact LR180 fins has 3,9m 3 blades 

with 15 kW actuators, while the twice as 

powerful LR250 is substantially larger 

(6,5 or 7m 3 ) but still retains a relatively 

small footprint inside the hull. Both 

models support four-fin arrangement 

and cover the range of yachts from 50 to 

100m in length. The next generation of 

products, Stabilis 5.0, will have a finetuned 

smart control algorithm that considers 

sea conditions to provide immediate 

feedback on roll motion reduction. 

Capiello hopes that old beliefs will soon 

go away and electric stabilizers will become 

standard, at least in the yachting industry. 

However, it seems that hydraulic 

competitors are not ready to give up and 

lose ground yet. 

Key products of SKF Marine include 

energy-optimized hydraulic retractable 

fins: type Z provides roll damping both 

underway and on anchor, while type S is 

optimized for stabilization on the move. 

When not used, these fins are neatly 

housed in hull pockets with optional inflatable 

covers that prevent the laminarturbulent 

transition. Low drag translates 

into fuel savings and lower emissions. 

Type Z and S fins feature anti-vortex tip 

fairings which increase lift, allowing 

smaller fin area. To reduce the loading of 

the power system, SKF added battery 

support that lowers peak load and noise 

levels while improving the dynamic response 

of the system. Fin control units 

allow fully automatic operations based 

on adaptive algorithms, as well as custom 

modes with single-fin or twin-fin use. 

In order to keep up with current 

trends, SKF Marine has joined to electric 

revolution and developed type EFZ system 

specifically designed for 50+ m 

yachts. It boasts all benefits of electric fins 

including 360° rotation, small footprint, 

low noise and vibration levels (30% and 

80% less correspondingly). Moreover, 

non-retractable type EFZ offers automatic 

walk back function which prevents 

forward movement of the hull at zero 

speed, and automatic heading assist. Last 

but not least, it allows to recuperate motion 

energy to power the actuators or 

even feed it into on-board ESS. EFZ supports 

both DC and AC network integration, 

requires less maintenance compared 

to hydraulic units, and suits well 

for retrofit installations. 

Quantum Group offers three stabilizing 

systems based on different principles. 

Dyna-Foil uses retractable foils that extend 

underway and act as an airplane flap 

creating the lift force and compensating 

the roll motion. At zero speed, foils perform 

precise swings (range 140°) like we 

do with our arms to control posture when 

floating in the water. Dyna-Foil is available 

as a pocketed or non-pocketed version 

to fit for various hull geometries. 

MAGlift stabilizers are based on the 

Magnus effect created by spinning rotors. 

Underway they are kept in certain position 

and change the direction of rotation 

to create necessary lift. When at anchor, 

swinging motion is added to effectively 

dampen the roll. Finally, semi-retractable 

Quantum XT rotating fins feature extending 

»blades« that enlarge the total fin 

area by 30% for more effective stabilization 

at zero speed. All these systems are 

hydraulic and have been installed on 

many super yachts from renown shipyards, 

including Lürssen, Oceanco, and 

Nobiskrug.

INDUSTRY NEWS 

AB YACHTS & MAIORA 

MAN Engines strengthens partnership with Next Yacht Group 

The renowned engine manufacturer 

MAN Engines continues its successful 

collaboration with Next Yacht Group 

Srl and will act as the exclusive supplier 

for new models of the Maiora and AB 

Yachts brands. The latest development, 

the 30-litre V12X yacht engine with an 

impressive 2,200 hp (1,618 kW), will 

power the powerful AB95 with a threemotor 

system. »For our latest coup – 

the AB95 – we are relying on nothing 

less than the latest generation of engines 

from MAN Engines,« says Giorgio 

Mattei, Vice President of Next Yacht 

Group. 

Since 2019, through its Italian Importer 

Ranieri Tonissi SpA, MAN Engines 

has been a premium supplier of MAN 

V12–2000 engines for the three-engine

YACHT EQUIPMENT | METS 2023 

Sustainable solutions 

Mets was again a hub for new yachting equipment. Much of the focus here was on 

electromobility and alternative drive technologies, which was reflected not least in the 

nominations for the annual Dame Awards 

© Maservis 

Many of the products nominated for the Design Awards were 

in the field of electromobility. The main prize also went to 

the Finnish company Oceanvolt, which presented the HighPower 

ServoProp 25, an electric sail drive that can generate energy while 

sailing. The jury praised the 25 kW electric drive as an excellently 

designed and constructed product that should significantly advance 

the electrification of propulsion solutions in the 45 to 

70-foot sailboat segment. The system can generate 5 kW of power 

when the yacht is moving at ten knots of boat speed. The simple 

installation and ease of maintenance for long-distance sailing 

were also rated positively by the jury. 

One of the favorites for the main prize at the Dame Awards was 

the interesting EcoCube project by the Croatian company Maservis. 

This is a floating, solar-powered collection station for waste 

and wastewater from ships, consisting of natural fibers and bioepoxy 

resin. »We have noticed that all types of waste are being discharged 

into the sea because there are no suitable collection points 

available,« says the company. »The only collection points for solid 

waste are in marinas and these are usually overloaded.« Maservis 

wants to offer a solution to this problem with the EcoCube.. 

Technologies for a green future 

Away from the spotlights of the awards, there was also plenty for 

electrical and sustainability enthusiasts to see in the Start-Up Pavilion 

area. For example, the company Open Waters Solar presented 

its next generation of marine solar panels – highly efficient 

solar cells embedded in a glass fiber/epoxy composite laminate 

and protected by a UV-resistant coating. This protective layer 

Solar-powered collection station from Maservis, one of the favorites for the 

Dame awards at Mets 

makes the solar panels extremely robust and even easy to walk on, 

allowing a wider choice of suitable installation locations on 

board. Thanks to the lightweight materials used and optimized 

construction methods, Open Waters Solar panels are significantly 

lighter than conventional solar modules. Thanks to the 

high adaptability and flexibility of the solar panels, the system can 

be tailored to any yacht size. 

The wind turbines from Dutch company Flag Turbines were 

also an eye-catcher. The innovative Flag Turbines harness wind 

energy in an environmentally friendly and sustainable way. Unlike 

conventional wind turbines, the Flag Turbines system operates 

at lower rotational speeds and thus avoids noise and vibrations, 

while at the same time being able to deliver a large 

amount of energy thanks to variable blade adjustment. The device 

is available in various sizes and can be installed on both 

smaller boats and large yachts. 

The start-up Pascal Technologies provided a breath of fresh air 

in the field of electromobility with its AirHull solution. The Air- 

Hull is a next-generation Surface Effect Ship (SES) solution that 

creates an air cavity between the water and the ship. According to 


METS 2023 | YACHT EQUIPMENT 

the company, the technology significantly reduces energy consumption 

at high speeds compared to conventional hulls, enabling 

electric boats to have a much greater range. The system 

uses a blower to force air into the cavity under the vessel, creating 

an overpressure that partially lifts the boat out of the water. This 

technology is similar to conventional SES solutions – but Pascal 

AirHull is unique in that it uses a special hull design and a flexible 

flap system to keep the air inside the cavity. The system is also 

controlled by a ride control system that ensures the boat moves 

smoothly and efficiently. 

In view of the guidelines against biofouling recently issued by 

the IMO, products such as the antifouling cover from the French 

company K-ren and the Hullbot cleaning robot from the company 

of the same name also attracted a great deal of interest. According 

to the manufacturer, the antifouling cover – a type of 

coating that is pulled over the hull of a boat while it is in the marina 

– makes it possible to avoid the regular maintenance costs that 

would otherwise be incurred to remove fouling from the hull. At 

the same time, the coating offers a sustainable alternative to environmentally 

harmful antifouling coatings and is 100% recyclable. 

The cleaning robot from the company hullbot takes a slightly 

different approach to the problem of biofouling. This is a fully 

automated and autonomous cleaning system that is able to inspect, 

record and remove fouling from the hull of a boat independently. 

The H6 drone consists of cost-efficient, modular hardware 

and a special underwater vision system that enables precise 

localization and navigation. 

Build lighter 

Meanwhile, the start-up Shapewave presented a completely new 

and disruptive technology at Mets. The company has developed a 

system for calculating and manufacturing complex internal 

structures for inflatable parts using proprietary robots. »We develop 

and manufacture inflatable structural parts using our proprietary 

Shapewave tool chain. 3D CAD model in, assembled 

part out. This is completely new in the industry,« explained Rudo 

Enserink, founder of shapewave. »We can create all shapes, colors, 

prints, and weight and precision classes, while our software 

allows us to evaluate the outcome before anything is built. Our 

parts are lighter, more durable and more robust than anything 

comparable.« For example, the company can close the gap between 

soft sails and rigid batten wings made of carbon. Inflatable 

sails, for example, have the advantage that you can simply deflate 

them after use and roll them up for transportation. 

Composite material specialist Hexcel also contributed to the topic 

of lightweight construction. The company presented its latest developments 

in the field of lightweight material technology with the materials 

IM2C and HM54. »By using our experience in carbon fiber 

production and the development of resin systems, we have created 

two outstanding products for the marine sector,« said Claude Despierres, 

Hexcel Vice President. The two new materials are intended 

to provide high-performance yet lightweight building blocks for designers 

and engineers working on high-performance structures in 

superyacht, commercial marine and wind vessel applications. 

biggest problems facing marinas and tourist ports today. At least 

that‘s according to the Greek start-up SaMMY, which presented its 

cloud-based IOT platform at the Amsterdam trade fair. This is designed 

to enable skippers and captains to search, compare, reserve 

and securely pay for a berth quickly and easily using on-demand 

services (web, widgets, mobile apps). The platform offers integrated 

and comprehensive digital services that are revolutionary for the 

yachting industry market, combining real-time berth allocation 

with efficient port management and IoT-enabled mechanisms. 

Of particular interest to the large super and mega yacht segment 

was the appearance of CMC Marine, the specialist for electrical 

stabilization. Founded in Italy in 2005, the company develops 

stabilizer, thruster, steering and control systems for the maritime 

market. At Metstrade, the company presented its new stabilizer 

models LR 180 and LR 250. The latter is the largest electrically 

operated raft system the company has ever produced. The 

two new units are designed for vessel lengths of 50 to 100 feet. According 

to CMC, the algorithm of the new series, due to be 

launched in spring 2024, improves onboard performance and 

takes full advantage of CMC Marine‘s Stabilis Electra system, including 

instant feedback to reduce sway and performance optimization 

based on sea conditions. The company also plans to invest 

in expanding its range of electrical products. To this end, 

CMC Marine has entered into a partnership with Gyro Marine to 

add gyroscopes to its product range. 

Metstrade 2023 took place for the 35th time in fall 2023 and 

celebrated this anniversary with record-breaking numbers of participants. 

1,540 exhibitors – 240 of whom were exhibiting in Amsterdam 

for the first time – from 53 countries gathered in the 11 

halls of the RAI Amsterdam to present their products to around 

18,630 visitors from all over the world. 

»Our team is committed to ensuring that Metstrade facilitates 

the connections and business needed for a successful year. Without 

the creativity and entrepreneurship of the supply chain, there is no 

marine industry. Our figures for 2023 are impressive, but they 

don‘t tell the whole story. We are especially grateful to have received 

so much positive feedback about the quality of interactions between 

our audience and exhibitors over these three days,« said 

Metstrade Director Niels Klarenbeek after the show.

HANSA YACHTS INTRODUCES | MATHIAS PEIN 

© Piening Propeller 

»Smooth running guaranteed« 

The German company Piening Propeller is a specialist for propellers and stern gears. 

CEO Mathias Pein explains why his products are often not seen but so important to 

owners and guests 

HANSA YACHTS: For most yacht owners, a propeller is probably 

a propeller. You have a more nuanced opinion, don‘t you? 

Mathias Pein: Well, yacht owners primarily notice the things on a 

yacht that they can see or even touch. People are happy to spend 

money on beautiful and appealing or particularly comfortable 

things. The propeller, on the other hand, is not seen and is easily 

regarded and dismissed as a mundane part of the propulsion technology. 

However, many people are not even aware that a new propeller 

is one of the real aesthetic »gems« of a yacht. Nor do they 

realize that they would not really be able to enjoy many other 

beautiful things on board while sailing or even sleep peacefully if 

the propeller(s) were not precisely adapted to the yacht in question 

and matched to the overall propulsion system. Thanks to an individual 

design and adequate production, the propeller ensures that 

the ship‘s propulsion power is ideally transferred to the water and 

that, in addition to the propulsion of the ship, the smooth running 

that is so important on yachts is guaranteed. 

How important are superyachts for Piening? And which segments 

are covered in addition? 

Pein: In our 95-year company history, our products have traditionally 

come from the commercial shipping sector, but in the last 25 

years, superyachts have also become a very important market segment 

for Piening Propeller. Together with navy and research 

vessels, whose system requirements are also very high, they belong 

to our market segment of »high-performance propulsion systems«. 

These generally form the »Piening Propeller Power Package«, consisting 

of gearboxes (ZF), complete shaft systems, hydrodynami-
