with a passion for performance 

Message from CEO Richard Macalister 

The decision to purchase the majority holding in Nexus Marine along with my business partner Dean 

Barker in early 2009 was an easy one as we had long been involved with distributing the Nexus brand 

in New Zealand and were impressed with the design quality and reliability of the products. 

Nexus Marine is based in Sweden and our two other partners Jan Silfven and Jonas Magner have had 

a long association with Nexus from the time it was created as a result of a de-merger of the marine 

division from Silva one of the world’s oldest and most respected marine instrument developers. We 

all share a love of sailing and our combined knowledge of yachting, from the top end race market 

through to the family cruising yacht, gives us a real understanding of needs of the yachtsman and the 

conditions in which our instruments must perform. 

In a market where mass manufacturing has decreased specialisation, we remain focused on precision 

instrumentation for yachts. Our brand is driven by performance and reliability, and has a business 

model that allows race yacht innovations to surface in the recreational market. 

You can trust Nexus to collect analyse and display the data that informs your sailing decisions. From a 

foundation of Swedish precision and excellence, Nexus looks always to the horizon of innovation.

DEAN BARKER – HELPING TO HELM NEXUS 

As a major shareholder in Nexus Marine, Dean Barker is able to bring his experience at the 

highest level of yacht racing to the boardroom table. His integrity, extraordinary focus and 

passion for sailing are a perfect fit with the Nexus philosophy. 

Famously calm under pressure, Dean Barker approaches the 

yacht equipment business in the same way he approaches 

America’s Cup racing. Second is not good enough. 

“Getting involved with the marine industry is a natural 

progression for me”, says Dean Barker. “Nexus represents the 

sharp end of innovation and the company’s business systems 

ensure that there’s no room for compromise with quality and 

manufacturing standards.” 

Dean began his sailing career at 10 years of age and collected 

an impressive range of yachting titles in P-class and Laser 

yachts before he graduated to the unforgiving world of 

matchracing. His first taste of America’s Cup campaigning 

came when he was invited to help Team New Zealand with 

their preparations for the 1995 campaign. While he declined to 

join the racing in San Diego, opting instead to concentrate on 

his Olympic Finn obligations, Dean signed on for Team New 

Zealand’s 2000 defence of the cup. 

It was Dean’s task to provide the Team New Zealand race 

team with a worthy competitor during preparation for the 

defence. He helmed the tune-up boat, often getting the better 

of Russell Coutts at all stages of racing. America’s Cup history 

was made when Dean, aged just 26, helmed NZL60 to victory 

in the final race of Team New Zealand’s 5-0 ‘blackwash’ over 

challenger Prada on Thursday 2 March 2000. 

Dean continues to be central to New Zealand’s America’s 

Cup and Louis Vuitton Trophy ambitions. He also hopes to sail 

in the next Tour de France à la Voile. The challenge is raced 

in new Archambault-designed M34’s, which are equipped 

with Nexus instrumentation. “Getting selected as the official 

electronics supplier for the Tour de France à la Voile M34s is a 

huge tick for Nexus”, says Dean.

A Passion for development 

Since its creation in 2006, Nexus Marine, has achieved a leading market position offering reliable and accurate 

products with innovative features and designs focused on the unique requirements of the sailing yacht. 

Leading the research and development team is Jan Silfvén who came to Nexus from the demerger of Silva. He 

has over 20 years experience in marine electronics development. Added to this he is a keen sailor giving him a 

huge understanding of the requirements of both the racing and recreational sailor. Jan works closely with Dean 

Barker in the development of new products for the racing market. 

Jan Silfvén commented: “We really believe that having one of the worlds best racing sailors on our research and 

development team gives us a leading edge in understanding the needs of the racing sailor and ensuring we can 

provide the most advanced technologies for our customers”. 

In addition to the input from Dean, Nexus maintains a pro-active research programme and is attentive to feedback 

from all customers, agents, sales representatives and sailors in order to know the best way to improve the existing 

products 

The company operates both in-house and on the water testing with a view to improve the products’ performance 

and development of new products, always with the intention of ensuring they are satisfying their customers who 

look for advanced equipment that give safety, simplicity and improved functionality on the water. 

The team at Nexus understands the unique demands of the yachtsman and is passionate about developing 

products for you. 

Wind transducers: the twin fin technology 

Our wind transducers are all based on the same twin fin technology. It features a three-bladed propeller and double 

wind vanes, which are toed in to give extremely good stability in both low and high wind speeds. The three-bladed 

propeller, unlike the more common cups design, is always 100% efficient. That, together with the optic reading 

technique, makes Nexus transducers superior at low wind speeds and also provides for excellent linearity. What’s 

more, all our wind transducers are mounted on a carbon arm for more resistance and durability. 

nexus New generation 

adBOX 

The new adBOX has been created by us to expand the ability of the Nexus Network 

to connect to an increased range of transducers and sensors giving you even more 

flexibility to design a system that meets your specific requirements. 

HPC Compass 

The HPC Compass features a 6-axis configuration that also incorporates heel and 

pitch. It provides exceptionally accurate vital data, such as true wind angle, even

NX INSTRUMENTATION - SAIL INTO THE AGE OF WIRELESS 

The NX range – precision instruments 

for sail and power 

You might not be battling around the buoys every weekend, 

but you still deserve the very best in marine instrumentation. 

For too long the racing boats have had the monopoly on stylish 

design, top quality displays and the latest in computer and 

networking technology. It’s time to level the playing field. 

Nexus NX instrumentation offers cruising yachtsmen an entrylevel 

system that combines precision, elegant styling and top 

quality displays with a flexibility that allows your system to 

grow with you as your needs and ambitions develop. 

While the NX system has a race boat pedigree, the system is 

designed to be quick to set up and simple to operate. Cabling 

has been kept to an absolute minimum, in fact done away with 

altogether as far as the wireless wind transducer is concerned, 

to keep installation as easy as possible. 

Easy system expansion 

Start with a single Sea Data display, WSI connection box and 

log transducer that gives your boat speed and distance run, 

and then add additional capabilities as your needs change, 

such as combi and wind transducers, with all the information 

transmitted by a single cable. Or, if you choose, you can have 

multiple multifunction Sea Data instruments on deck or at the 

chart table. The NX Wind Instrument adds the final touch, 

displaying true and apparent wind data in digital and easy-toread 

graphical form. 

Information at your fingertips 

The Sea Data lets you switch between depth, speed and wind 

angles quickly and simply using buttons and menus. It couldn’t 

be simpler. The information you request will be displayed in 

large, clear digits that all your crew will find easy to read. 

NX DISPLAYS 

The NX system offers two, versatile displays to meet all the needs of the cruising navigator; the digital 

multifunction Sea Data and the digital / analogue Wind Instrument, for maximum convenience and flexibility.

How to select your transducer? 

Art.No. 22931, NX Start Pack 1 

Art.No. 22932, NX Start Pack 2 

The NX range offers various possibilities with transducers. The choice of your transducer will depend on 

the information you want and on the size of the hole you have in your boat 

Two sizes of through-hull transducers exist: the 43 mm and the 52mm. At Nexus, we recommend 43 mm 

transducers, because they are more accurate at low speed. However, if you already have 52mm holes in 

your boat, we can provide the larger size. 

Finally, if you don’t want to make a hole in the hull, or if your type of boat isn’t compatible with through-hull 

transducers, you can choose the Nexus transom-mounted transducer, which delivers speed, depth and 

temperature data.

NX2 instrumentation 

Racing and cruising now have one thing in common – precise information 

While analogue instruments continue to play a vital role in navigation, due to the immediate impact they have on the 

visual senses, the majority of today’s sailors rely on digital displays for their essential information. Only digital can 

supply the level of precision needed to monitor minute changes in important variables, often down to as little as one 

hundredth of a unit. 

The Nexus NX2 system takes this advantage a stage further by linking all its digital instruments with a network. The 

benefit is that when new settings are keyed into one digital instrument, all the other instruments on the network 

receive the information simultaneously. This is an especially handy when a sailor wants to add trim values, activate 

lighting, clear the trip metre or calibrate instruments. 

Another important advantage is the ability to manage waypoints. You can enter or select waypoints from anywhere 

onboard - at the wheel or helm, at the navigation table or on the fly-bridge. 

Optimal function, readability and quality 

The network has been designed to connect three groups of core components in the most effective way. The NX2 

Range offers both digital and analogue instruments, a server and five different categories of transducer (log-temp/ 

depth/wind/compass/GPS). 

NX2 System and FDX 

NEXUS is the Latin word for “connection” summing up exactly what the 

NEXUS network is all about. The NX2 system allows full interfacing with 

other third party equipment, which is NMEA compatible, allowing a fully 

integrated system giving the user a vast array of information on three 

types of displays - the standard LCD, Analogue or large digit XL displays. 

NX2 systems are supplied with FDX software (Fast Data eXchange) 

opening the door to laptop convenience. FDX, together with the Nexus 

race software, increases the speed at which the information flows through 

the network by up to 10 times. FDX extends the frontiers of sailboat 

racing. 

Nexus Race Software also revolutionises the way calibration is done within 

the system. Now, from the laptop, you can adjust settings, calibrate and 

auto-deviate the compass. Difficulties in calibrating wind speed and wind 

angles become a thing of the past – the unique Nexus software does the 

job for you. 

So if you are a cruising or racing yachtsmen who requires integration with 

computers, chart plotters or other equipment the NX2 system allows 

you to build a system with a range of displays which is perfect for your 

requirements. 

Nexus Server 

The Nexus Server functions as a terminal station for the Nexus Network to 

which all transducers, NMEA input and output are connected. Furthermore, 

the Server has outputs for external M.O.B. (Man Over Board) and trim 

buttons and an external alarm. All screw terminals are clearly marked for easy 

installation. The NX2 unique plug wiring system enables a tidy and clean 

installation below deck with no excess cables.

NX2 Steer Pilot 

You can select your steering reference from 

several options: 

• Compass steering (up to 2 course 

memories) 

• Apparent wind angle to follow wind shifts 

• Waypoint steering (BTW) without 

compensation for drift. 

• Course to steer (CTS). Same as BTW but 

including compensation for Drift

NX2 Wind 

The NX2 analogue Wind angle 

instrument displays true and apparent 

wind angle. Fields are clearly marked 

in red and green allowing for superior 

readability, especially during night 

navigation. The scale and display is 

illuminated.

nx2 analogue 

NX2 Steer Pilot 

This is our most interesting and effective analogue instrument, drawing information from the electronic compass, waterspeed 

sensor and the GPS to create one single piece of critical data represented by the needle! The Steer pilot enables 

the helmsman to steer to an exact course using updated steering information refreshed 5 times every second by the NX2 

server. The instrument needle instantly indicates the smallest deviation from the intended course or preferred wind angle. 

The Steer Pilot can also guide the helmsman to steer by the needle using the data from a Polar Diagram as reference. 

On a downwind course, the Steer Pilot enables the helmsman to steer the optimum course for the best VMG, refreshing 

the data five times per second. 

So, how do I use it? It’s really very easy. With a steering wheel, imagine that the instrument needle is connected by an 

invisible wire to the centre of your wheel. When the deviation appears, just turn the wheel as if it was connected to the 

needle, back to a straight up position, it’s that easy! 

With a tiller, imagine that the end of the tiller is ”fixed” at the tip of the needle and that you can pull the needle back to 

its straight up position just by ”dragging” it there, it just works! After a few minutes training you will be able to steer your 

boat in a straight line without even thinking! 

NX2 Compass 

The Nexus NX2 analogue Compass repeater 

and compass heading displays have superb 

readability. A sensitive pointer on the 360° 

scale gives an accurate and stable compass 

heading.

NX2 SAIL PACKS 

The NX2 sail packs are the ideal foundations from 

which you can build your own custom system. The 

packs can provide you with speed, depth, heading and 

wind data. By using the revolutionary solid state HPC 

compass, which calculates heel and trim, it will deliver 

highly accurate wind data. 

The NX2 server allows complete NMEA interfacing 

capability, as well as proprietary protocol FDX 

interfacing, allowing easy expansion of the system 

and connection to a computer. All of the NX2 

sail packs can be interconnected with any other 

instrument via the NMEA port such as radar, plotter, 

auto pilot, vhf etc.

Art. No: 69913-52, NX2 Cruiser Pack 

Every now and then a new sailboat comes along that fulfils a real need in the market. Launched in July 2010 the J/111 

is a sleek, speedy, one-design 36 footer that is the ultimate day sailing, racing and weekend cruising sailboat. Designed 

to be the best performing, easiest-to-sail boat of its size on the market it also offers the creature comforts needed (6’ 

headroom) to satisfy the occasional overnight cruise. 

The new J/111 hull #1 is fitted with 4 mast mounted XL20’s that, by using either the ”hotkeys” on the two cockpit 

mounted NXR Multi controls or the on board computer, with a single button press will display the information the crew 

needs. The four cockpit mounted Multi XL’s constantly provide a further 8 lines of data, the selection of these again being 

made using either the NXR Multi Controls or the on board computer. An Autopilot display/control completes the selection 

of digital displays fitted. In addition to the digital displays two analogue ”Steer Pilot” displays are fitted, these can be set 

up to give the crew a clear visual indication of alterations in course that may be required to get the very best out of the 

boat. 

As J Boat says “It’s all about versatility and the joy of sailing - how to have the most fun out of the time and resources 

invested” a sentiment easily understood and shared by the team at Nexus Marine.

NXR instrumentation 

The NXR racing instrumentation system is the ultimate in integrated networking for sailors who demand the best. It delivers fast 

update speeds of 8Hz and a range of displays that allows both racing and cruising crews to select a data combination that will 

meet their exact requirements. 

nexus new generation: 

The Nexus NXR new generation enables you to monitor load cells and to make a Nexus complete integrated system for your racing 

boat improving your performance. The NXR new generation with the adBOX(analogue digital) and the nWIND also enables weight 

savings thanks to an innovative wiring technology. One of the new features of the NXR range is also the new bonded NXR Multi 

Control displays, avoiding any moisture behind the screen even in the worst conditions. 

PC integration/calibration 

Every system is supplied with the FDX software, which allows 

the user to calibrate the system, easily and quickly from their PC. 

FDX software permits fast data exchange on the network and up 

to ten lines of race software generated data to be displayed. 

FLEXIBILITY of displays 

The NXR system has a wide range of displays, allowing you 

to tailor-make an information system that suits your individual 

requirements. The NXR multis come with two options: standard 

LCDs and the innovative inverted LCD, which reduces the light 

shining from the display at night to allow easy night vision. Large 

digit displays are available with the XL20 (46mm digits) and 

the XL30 (63.5mm digits), so that essential data can be easily 

seen on even the largest yacht. NXR analogue displays are also 

available for users who prefer data displayed by way of a pointer. 

Additionally, you can select between red and green backlighting 

for optimal viewing at night. 

Accuracy of information 

A huge amount of time, energy and knowledge has been poured 

into developing NEXUS transducers, to ensure the accuracy 

of the information entering the system. The brief given to the 

research and development team was to think outside the square 

and design the best anemometer available. The team came up 

with a low drag unit that utilises a twin fin for a more stable wind 

direction, while utilising a propeller for measuring wind speed. 

The result is greater accuracy at low wind speeds. Coupled with 

that is a leading-edge HPC compass that utilises heel and trim to 

provide an accurate heading, as well as true wind information. 

Ease of use 

The displays are designed to be remarkably easy to use. Four preprogrammed 

menu pages ensure that mast displays can be set 

up with the push of one button. Come to the top mark and hoist 

the spinnaker, push one button and the cockpit crew can have all 

the information they need.

M34 and Nexus instrumentation add extra 

excitement to the 2011 Tour de France á la Voile 

The annual Tour de France á la Voile is a multi-stage, monthlong 

race that links the English Channel to the French Riviera. 

With an original blend of buoy racing and lengthy offshore 

legs, it is one of the world’s most challenging one-design 

series. 

The inaugural Tour de France á la Voile was sailed in 1978. 

Since then more than 20,000 people have sailed the race, 

including many famous yachtsmen – Loïck Peyron and four 

times America’s Cup winner Russell Coutts, to name just a 

couple. Due to three distinct rankings, this sailing challenge 

is not just for professionals - amateurs and students can rub 

shoulders with the elite sailors. Of the 28 boats that took 

part in the 2010 event, entries were divided almost equally 

between students, amateurs and professionals. 

Like its famous cycling counterpart, the Tour de France à la 

Voile does a marvellous job of showcasing France’s scenery. 

The event visits around 10 harbours along the French coast. 

These vary from year to year, so that the excitement is shared 

amongst the coastal towns. Midway through the race, the 

boats are transported between the Atlantic Ocean and the 

Mediterranean Sea by road. 

The 2011 event will see the introduction of a new yacht design 

– the M34, which is built by Archambault and designed by 

Joubert-Nivelt. This design was selected after an extensive 

review of more than 20 yacht designers and builders. 

“I think it will be much more fun than a typical IRC boat of its 

size,” says Philippe Paturel of Archambault North America. 

“And, because it was designed with a lot of consultation from 

many Tour de France competitors, it will be well developed.” 

In terms of the overall design, the M34 is a powerful boat 

with a formidable sail plan. Its higher freeboard (relative to 

the Farr 30) is a major contributor to superior ocean-passage 

worthiness and it’s fully compliant with ORC offshore 

regulations. 

As a global player in the design and manufacture of 

navigational instrumentation, Nexus Marine is proud to have 

been chosen as the exclusive electronics supplier for the M34. 

All the boats will be fitted with the NXR range, which features 

the newly released Nexus XL20, a large digit repeating 

instrument for high performance boats. The XL20 allows 

sailors to customise the information they receive and vital data 

is easily visible, thanks to its larger screen and selectable red 

or green background lighting. 

“Getting selected as the exclusive electronics supplier for the 

Tour de France à la Voile M34 is a huge tick for Nexus”, says 

Dean Barker. “These boats and their equipment will lead the 

way in the future of one-design sailing and Nexus is excited to 

be part of it.”

transducers 

wind transducers: tHe twin fin tecHnologY 

Nexus has left nothing to chance. The best displays that money can buy will not make up for low-grade information sent from sub-standard 

sources, which is why Nexus has always paid special attention to the design and production of its transducers. 

Our wind transducers are all based on the same twin fin technology. It features a three-bladed propeller and double wind vanes, which are 

toed in to give extremely good stability in both low and high wind speeds. The three-bladed propeller, unlike the more common cups design, 

is always 100% efficient. That, together with the optic reading technique, makes Nexus transducers superior at low wind speeds and also 

provides for excellent linearity. What’s more, all our wind transducers are mounted on a carbon arm for more resistance and durability. 

Nexus offer a range of three wind transducers: 

Wireless Wind Transducer 

The twin fin wireless wind transducer brings all the advantages of wireless 

instrumentation to the cruising sailor. Gone are the complications and aesthetic 

issues of running wiring from the top of the mast down to the chart table. 

Instead, the wind transducer establishes a unique pairing using radio signals with 

the WSI connection box. This forms the core of the NX instrumentation system, 

ensuring that each transducer / server pairing is distinct from every other. The 

information is then fed from the WSI connection box to your Nexus network, 

thanks to Nexus FDX protocol. 

The twin fin design makes this a highly stable and accurate wind transducer. The 

internal batteries are continuously charged by a small solar panel mounted on the 

transducer arm, have a life of around three to four years, and are easily replaced.

WSI (Wireless Sensor Interface) 

Connection Box 

The Wireless Server Interface (WSI) 

connection box forms the core of the 

NX instrumentation system; the central 

point at which all the data collected 

from the transducers is processed 

and then sent down a single cable to 

the Sea Data and, if installed, Wind 

Instrument displays. Among its many 

functions, the WSI combines boat 

speed and apparent wind speed and 

angle, to calculate the true wind speed 

and angle. The WSI communicates 

directly with the wireless wind 

transducer via a unique radio pairing, 

and the slim and compact box is quick and simple to install. 

Art. No: 22927 WSI-box 

nWind Transducer 

New for 2011 the nWIND transducer 

connects directly to the Nexus 

network providing 30% faster data 

transmission to the system. The 

highly successful design of the 

masthead anemometer has been 

retained with the use of a propeller 

providing a more accurate True Wind 

Speed (TWS) in lighter air whilst the 

twin fin design gives a more stable 

True Wind Direction (TWD). An 

easy, snap-in attachment for mast 

mounting is included. The nWIND 

transducer provides a highly accurate 

output for the Nexus network.

nWind Race Transducer 

The nWIND Race Wind transducer overcomes the problem of upwash 

affecting the accuracy of wind information by raising the sensor above the 

mast top. 

The nWIND Race transducer connects directly to the Nexus network 

providing 30% faster data 

transmission to the system whilst 

allowing you to store calibration 

tables in the system for True Wind 

Angle (TWA) and True Wind Speed 

(TWS). The result is extremely 

accurate and fast wind data 

information which is all good news 

for the racing yachtsman. 

As with both the wireless and 

conventional forward-facing 

masthead wind sensors, each unit 

is factory calibrated to take out 

any sensor anomalies. This results 

in very accurate wind speed and direction information. These calibration 

values are permanently stored within the masthead unit. Using the FDX 

software provided with every NX2 and NXR pack, it is possible to calibrate 

the masthead unit to also take the effects of wind shear into account, 

making this a highly accurate wind sensor for both the racing and cruising 

yachtsmen. 

The nWIND Race transducer offers three mounting options: a conventional 

flat base, which is screwed to the top of the mast, a spigot type base, and 

for those unable to fit the vertical bracket a forward mounting option.

MRC Box (Mast Rotation Compensation) 

New for 2010 the MRC Box enables compensation 

for wind angle on rotating masts. It measures the 

angle and direction of mast rotation, enabling the 

pilot to steer and the system to display true and 

apparent wind information, which is corrected to 

allow for mast rotation. An electronic compass, such 

as the HPC, must also be fitted to any system using 

the MRC. The MRC weighs only 40 grams and both 

the unit and all direct connectors are waterproof.

nexus new generation 

adBox 

An exciting new product has been created by Nexus the adBOX 

(Analogue Digital Box) which was originally designed for a 62 m ketch 

built at the reputable superyacht builder Alloy Yachts in New Zealand. 

Expansion of the NXR system with additional equipment at any stage is 

simplified as the addition of the adBOX will allow additional information 

to be integrated into the Nexus network. 

Nexus is Latin for connection and the addition of the adBOX expands 

the ability of the Nexus network to connect to an increased range of 

transducers and sensors giving you even more flexibility to design a 

system that meets your specific requirements. 

The adBOX allows you to connect analogue signals into your system 

such as load cells and string pods. 

HPC Compass 

HPC (Heel Pitch Compensated) solid state Compass Transducer uses 

the latest materials and precision engineering techniques to produce the 

highest quality data of its kind. It is accurate to +/- 1˚ up to a maximum heel 

angle of 60˚ and with an output rate that can be set up to 10Hz. Now also 

available as a NMEA compatible unit which works with all NMEA 0183 

systems. 

The HPC features a 6-axis configuration that also incorporates heel and 

pitch. It provides exceptionally accurate vital data, such as true wind angle, 

even when the boat is heeled right over. 

Nexus HPC Compass represents a real advance in high-end racing 

compass transducers. It combines accuracy and the ability to integrate 

with a wide range of navigational systems with a stylish, sophisticated 

and compact structure that requires minimal space and maintenance. Now 

a standard component of the Nexus multi-instrumentation systems, the 

HPC transducer is also available as a stand-alone unit for owners looking to 

upgrade their existing systems. The entire instrument is the size of a small 

mobile phone and weighs just 40 grams. 

Heel Switch System 

The team at Nexus developed the Heel Switch System to solve the 

speed discrepancy problems experienced when the speed and depth 

transducers need to be installed away from the centre line. These 

variances are common on multihulls, modern day short-handed yachts 

and older classic keel style designs. 

The Heel Switch System consists of two small heel boxes - one for 

port and one for starboard - into which the two pairs of transducers are 

wired. These boxes process the raw speed, water temperature and 

depth data into the Nexus protocol, automatically selecting the correct 

box depending on which tack / gybe the yacht is on. 

The switching between the port and starboard boxes is done 

automatically depending on the heel of the boat, which is provided by a 

HPC Compass. If a compass isn’t fitted, the switching will be made on 

the apparent wind angle. 

Specifications 

The Heel Switch Systems includes 

two heel switch boxes (one port and 

one starboard) and one 0.4m interconnection 

cable.

The main difference between a powerboat compass and a sailboat compass is the heeling angle limit and the damping 

characteristics. A powerboat compass has fixed lubber lines to maintain the best dynamics, while steel boats need 

compasses with D-correctors or soft iron correctors. 

Individually balanced

Which size of compass do I need? 

What is the size of your boat? 

If the compass will be read from a distance you will need a bigger 

compass. The simple thumb rule is: a boat longer than 7,5 meters 

(25 feet) requires a 100 series capsule or larger. 

70 series has an apparent scale of 70mm 



What type of mounting do I need? 

Where will the compass be mounted? 

There is a Silva compass for every mounting need. In the 

bulkhead, on the dashboard, on the headlining, on the mast 

etc. All models are designed so that no unnecessary drilling is 

needed. 

Why do I need a compensator? 

We strongly recommend the use of a compensator, and not only 

in steel boats. Almost all models can be supplied with a built-in 

compensator to avoid magnetic disturbances. Such disturbances 

will be found on any boat, the source varies from loudspeakers to 

the radio, engine, wipers, electronic instruments (not NX2) and 

other metallic components. Remember that the distance to the 

source is more critical than its strength. 

All Silva marine compasses have 5 years warranty.

Bulkhead mount compasses 

The bulkhead mount compasses (70P, 100P, 102B/H, 100B/H and 125B/H) are specifically designed for 

sailboats and yachtsmen demanding absolute accuracy with a steady card in all conditions and 

125 

accommodating high heeling angles. 

Bulkhead-mounted front reading series with 3 yellow lubber lines for the 100 series and one yellow lubber 

line for the 70 series. The gimballed lubber lines stay vertical even if the boat is heeling (max 45°). The two 

extra lubber lines at 45° offset permit reading from the rail or an off steering position mounting. 

Flush and pedestal mount compasses 

The flush and pedestal mount compasses are designed for those yachtsmen that demand absolutely accuracy 

and a steady card in all conditions, despite the heeling angle. 

An extended centre needle eliminates parallax errors and the gimballed yellow lubber lines stay vertical 

even when in rough seas. Compensation is standard. It is also possible to add a heeling compensator.

Sail race compasses 

The Elite racing models have been developed by the world’s top racers and Olympic sailors. The tactical scales and quick 

readability give a critical advantage. The cone-shaped card with gimballed lubber lines has a main steering scale on the 

horizontal part of the compass card and a tactical scale on the vertical edge of the card. 

150 

Detecting wind shifts may be the tiny difference between winning and losing. Silva’s tactical scale grades from 0-20 and the 

figures correspond on port and starboard tack. If the reading on starboard tack is 2 the reading on port after tacking should 

also be 2. In this way you only have to remember one figure. This is a great benefit in triangular course sailing where racers 

need to watch the wind shifts, rather than their actual course. 

The double scale, divided into a green starboard and a red port scale, allows sailors to read the actual course on port and 

starboard tack from the helmsman’s normal position at the rail. You no longer have to add 45° to your reading. The green and 

red memory arrows tell you to tack if the figures decreases on starboard tack and to tack if the figures increase on port. The 

top scale allows you to read the course on downwind or to check the start line position. 

73R 

73R is the perfect combination compass. It can be installed in any 

inclination or position with a bracket that allows for fast and easy 

removal. The handle makes it useful as a sighting compass; simply 

remove the compass from its bracket and sight the mark to determine 

the bearing. Tactical compass scale on the vertical part of the card.
