Background: Hundreds of hull shape variants can be
produced within hours. Each of these shapes is different,
yet still meets the hull constraints we have identified.

Exploring IDEOS
Our new Integrated Design-Space Exploration and Optimization System allows us to
evaluate thousands of potential designs through automation. We’ve combined our
tools and resources together in a suite of automated tools which assist in developing
and analyzing new hull shapes.
Farr Magazine — Summer 2017 5

Feature
IDEOS
We are proud to be announce the availability of our
Integrated Design-Space Exploration and Optimization
System (IDEOS). IDEOS is the product of 18 years of continuous
development focused at producing the fastest, most refined
racing yacht designs.
Yacht design has always been a balance between artistry,
science and technology. The rapid development of
computational technology over the last few decades has
had a dramatic impact on racing yacht design. We can
perform significantly more detailed analyses of aero and
hydrodynamics that enable us to capture small design
differences and predict performance to an unprecedented
level of accuracy. We have continually invested in the
refinement and expansion of our design tools to maintain our
technological advantage. Our clients have access to a level
of capability previously only available in America’s Cup-level
programs.
In the past, tight design deadlines and small research budgets
limited the amount of design space exploration that could
occur. We would develop a base design concept and then
build a small number of variants which would be manually
configured and analyzed. This process relied on the designer’s
experience and intuition to focus research on the biggest
potential for gains. It often left a large portion of the design
space unexplored.
The equation has changed. By leveraging these developments
and integrating our proprietary computational tool suite
under a common automation framework, we are now able
to evaluate thousands of candidate designs, compare their
performance potential and identify fruitful design aven ues
with an exceptional level of accuracy. This is made possible by
an exponential increase in computing power, the availability
of open source tools and the ability to access on-demand high
performance computing resources.
IDEOS is our umbrella framework that automates the
creation and evaluation of thousands of candidate designs.
This allows the detailed exploration of the design space and
the rapid identification of optimal design alternatives. The
underlying system facilities information transfer to a series of
component tools in an automated fashion minimizing manual
intervention and reducing potential sources of error.
We have already gained valuable insights into the subtle
balance between performance-enhancing factors with IDEOS.
We can now visualize trade-offs between displacement, sail
area, beam, bulb weight and even hull construction material
to understand how the optimal set of parameters varies with
different wind conditions and course makeups.
There are, however, significant risks to over-reliance on
these tools. Understanding these shortcomings has been
a core part of our development of this system from the
outset. Fundamentally, these optimization and exploration
algorithms will find any hole in our logic and exploit it. For
example, if our weight calculation scaling system doesn’t
properly account for some dimensional variations or there is
some numerical artifact in our force response surfaces, the
system will exploit it to find an artificial optimal design.
Sailing is a dynamic sport in a dynamic environment. As
advanced as the simulations have become, our ability to
capture these dynamic factors is still limited. It requires an
experienced eye and a good dose of intuition to be sure the
black box doesn’t lead to false conclusions.

How it works

WATCH: See a demonstration of IDEOS
Identify design variables, identify design objectives, and define constraints
In this stage, we define the kinds of hulls we would like to produce. We set different design variables (hull factors, sailplan, appendages), along
with objectives (a target IRC rating, cost, stability, performance), and constraints (hull fairness, rating limits, stability limits, interior limitations).

Using CAESES, a geometric
modeling and integration
engine, the process of
generating thousands of
candidate designs is fully
automated. The variables
and base hull shape
information is used by
several other programs to
develop candidate designs.
The process repeats for each
design.

Once the process has completed, each of the candidate designs is displayed
in a table. We can look at the features and specs of the design, as well as
visualize it. We can also look at the designs plotted together to examine
correlation between variables and establish what variables are most critical.

Fast 40+ Optimization
FYD has worked with the GP42 “Jubilee” team to get the best possible performance for their
yacht in the new Fast 40+ circuit based in the Solent.
Photos: Shaun Roster
Since Autumn of 2015, Farr Yacht Design has assisted the Jubilee
sailing team with modifications and upgrades to optimize for the
Fast 40+ circuit in the UK. As originally designed by FYD, this particular
boat is the lightest of the Fast 40+ designs, even after accounting for
her higher bulb weight, as verified by her certificate, despite being
longer than the 12.6 hull length limit of the newest Fast 40’s.
In 2016, Farr Yacht Design designed a brand new keel fin increasing
keel draft to the 3.0 meter class maximum for the Fast 40+ class. The
deeper fin increases righting moment by 8 percent and dramatically
increased the keel’s lifting efficiency. A new, specialized foil section
was created for the keel, to provide excellent high lift characteristics
and a wider groove. The new keel section was optimized to work with
the original hull and internal structure on the boat, and FYD specified
upgrades to the original carbon structure. Ultimately, Jubilee
increased the strength and stiffness of both the keel fin and related
hull structure while remaining the lightest boat in the Fast 40+ fleet.
For the 2017 season, FYD designed a new forestay fitting to permit
the upgrade to a new higher-load capable forestay. The new forestay
is accompanied by other structural upgrades to globally stiffen the
structure allow the boat to carry higher forestay & backstay loads,
critical for upwind performance.
Gregg Parker, boat captain of Jubilee, commented, “When we
purchased Jubilee at the end of 2015 we wanted to optimize her to
be competitive against the newer designs, we contacted FYD from the
beginning, it was a natural step to go back to where she started.”
“FYD were keen to help from the outset and we’ve had a rewarding
dialogue with them all the way through the modification process.
Initially we looked at keel and bowsprit as the first areas to add
horsepower, the design loop was quick and efficient despite the
different time zones with someone on hand to assist whenever
required. The latest round of changes are yet to be fully tested in race
conditions but early signs are promising.”
“The Fast 40+ fleet is providing hugely competitive and rewarding
racing with a close fleet where small errors are punished. The older
generation boats have all been working hard to make incremental
gains and remain competitive. We feel Jubilee’s light weight and high
bulb weight give us every opportunity to be competitive, it’s just up
to the 11 people sitting on top to deliver.”

Volvo Ocean 65
Over the past year Farr Yacht Design has been working closely with the Volvo Ocean
Race Boatyard on the refit of the 7 Volvo Ocean 65’s. The VO65’s were pushed hard in
the previous race and each boat has received a complete and thorough refit estimated
at € 1 million per boat. More than just cosmetic work, each of the boats has had a
complete ultrasound survey the results of which are correlated with surveys taken
during each boats’ build and throughout the race. Any laminate damage or issues
are reviewed by our lead structural engineer, Chris Cochran, and repair strategies
developed with the boatyard that insure the boats are one design compliant and as
robust and reliable as when they were launched.
While the refit process advances to its completion, the eighth VO65 for Team
AzkoNobel had its primary structure completed at Persico Marine before being
transferred to the Boatyard in Lisbon, Portugal to undergo systems fit-out and
finishing using the same process as the refit boats.
The next edition of the Volvo Ocean Race starts October 22, 2017 and FYD will be
supporting teams with performance analysis and on site at the stopovers to advise
on any necessary repairs.

Southern Wind 96
Farr Yacht Design is delighted to present our ninth design commission from Southern
Wind Shipyard. The new Southern Wind 96 is a stunning, thoroughly modern yacht
designed for the sailor who expects cutting edge design and superb styling in a fast,
safe, passage capable yacht equipped to contest any superyacht regatta.
FYD was given a free hand to develop the naval architecture concept. With Southern
Wind’s advanced construction technology and fanatical commitment to weight
control, we were able to create a light, powerful masterpiece with aggressive hull
styling, a highly advanced appendage package and a more than ample rig size. A
lifting keel with a draft range of 5.5 to 3.4m guarantees excellent upwind performance
and easy harbor access. Twin rudders were chosen to best match both the lifting keel
configuration and the wide, powerful transom.
The interior and deck styling are the product of Nauta Design and were developed in
concert with the overall concept to be the “new wave in the future of Southern Wind.”
The first yacht, “Sorceress” was completed in May 2017. She will make her racing
debut at the 2017 edition of the Maxi Yacht Rolex Cup, and will be displayed as a
world premiere at the forthcoming Monaco Yacht Show.

Infiniti 56C
Farr Yacht Design and Infiniti Performance Yachts are pleased to present
this conceptual package for a 56ft. high performance blue water cruiser.
The cruising boat market is lacking offerings that combine both sleek
modern styling with the latest in high tech construction methods
and design technology. The performance advantages that have been
developed and refined in the grand-prix racing world promise to
be equally revolutionary to the cruising sailor and we are excited to
redefine blue-water cruising with the Infiniti 56C.
The Infiniti 56 is a true high performance blue-water cruiser. It features
a modern low drag hull form coupled with a modern deck saloon that
seamlessly integrates the well-appointed interior with the cockpit
sailing and entertaining spaces. As presently envisioned, the boat
utilizes a lifting keel to allow for a deep center of gravity and light
displacement when under sail but reduced draft for easy access to port.
The boat features twin rudders to allow for excellent controllability in
all conditions. Unique for a yacht of this style is the electrically actuated
single transverse DSS foil that provides both significant stability and
reduced displacement.
The Infiniti 56 will set a new paradigm for performance in this size range
with the potential to sail at higher speeds and at lower heel angles
than anything else in class, while featuring improved sea keeping and
simplified sail handling.
This concept has been developed from the ground up to maximize
the benefits of the DSS system. It promises to provide unrivaled
performance across a broad range of conditions; able to perform well
inshore and excel in offshore conditions and ocean passage making.
