Owen Clarke Design 4th Generation Class 40

Owen Clarke Design have been involved with the development of Class 40's since the rule’s  inception back in 2005 and have produced nine custom/semi–custom and five production boats, since 2006. As well as designing the class champion in 2008 our designs have won or placed on the podium in events such as: Class 40 Mondial/ISAF Worlds, Route du Rhum, Round Britain and Ireland Race, Normandy Channel Race, Atlantic Cup, Bermuda Race, Bermuda 1-2, Marblehead-Halifax. Most recently the South African, Jaz Marine built 40 Degrees 2, finished third in the 2011 Transat Jacques Vabres sailed by British and American sailors Hannah Jenner and Jesse Naimark-Rowse.

Owen Clarke Design 4th Generation Class 40

Owen Clarke’s fourth generation Class 40 design has now been completed, is ready to commence construction and is available from a number of yards depending on the client’s specification and budget. This very latest development in Class 40 design is also available in kit form to be completed and fitted out by owners or yards in any country.
Kit boat available (depending on level of completion) from 157,000 Euro
Ready to sail, build South Africa (ex sails and electronics) 337,000 Euro
Ready to sail, build United States (ex sails and electronics) 608,000 US$

Combining the hull design development work carried out with American IACC designer Clay Oliver for the Generation 3 designs of (ex Cinnamon Girl) and 40 Degrees 2, this most up to date 2013/14 Class 40 design shares the same hull platform, with new cockpit and deck layout options, latest keel fin and rudder design, two spreader rig and structure in-line with the minimum ISAF Class 40 requirement of ISO 12215 Category A.

Unlike production Class 40s, whether the requirement is for an inshore or offshore racing program, OCD optimise the design to suit your requirements. Variable ballast positioning and sail configurations within the existing stock design can be adjusted to provide an optimum performance package for target events. Should the client have a specific race program in mind then a full custom design package with an R&D component is available and may suit a more refined approach.

Class 40 is intended to be a ‘broad church’ , while some sailors wish to race predominantly offshore others never complete a long distance event. It is a box rule that has produced yachts ideal in concept for the sponsored and corinthian sailor alike to sail short-handed in trans-oceanic races such as the Melbourne-Osaka, Route du Rhum, Round Britain and the AZAB. The concept of the class and the design is also to be capable of racing fully crewed (typically 3-5 persons) in classic events such as the Fastnet, Bermuda Race, as well as club racing and in regattas such as Spi Ouest and Cowes Week. The class has its own highly competitive ISAF Worlds and so excellent offshore and inshore sailing is available within the class without the expense and difficulty of finding and providing for a crew of ten, the number permitted on an IRC certificate for a 40’ boat.
As well as racing (and in most cases with their own division or starts) in established classics, Class 40’s now have dedicated races in both Europe and the USA and an example of the broad range of events and regattas available in any one season can be seen below.

February       Own division         Crewed            RORC Caribbean 600
March           Class 40 event      Double             La Solidaire du Chocolat, France - Mexico

September     Class 40 event      Double             Normandy Channel Race
October          Class 40 event      Crewed            Class 40 Worlds   
This by no means illustrates anywhere near all the events in which a Class 40 can or has been entered. In 2013 for instance twenty four Class 40’s had their own division in the double-handed TJV while in fully-crewed format twenty Class 40’s from eight nations took part in the RORC Fastnet Race. Up until 2011 and before two transatlantic races to the Caribbean were scheduled in the same period the TJV boasted more than thirty and the  2010 Route du Rhum forty four entrants.

The most recently launched OCD Class 40’s have been and 40 Degrees 2, built at FSCD (UK) and Jaz Marine (South Africa) respectively. These boats were launched and sailing within days of each other in September 2009. The same month 40 Degrees won its very first regatta, the 2009 Mondial, the class’s Worlds (prior to being recognised by ISAF) and followed this up with a second in the 2010 Normandy Channel Race. New to the class, Joerg Riecher's meanwhile chartered Cinnamon Girl in 2010/11 finishing fourth, just off the podium in his three class events.

Owen Clarke's second Class 40, Bolands Mill for UK mini sailor Ian Munslow was based on our first generation stock design and had a solid cast SG Iron keel fin which reflected where the class was at in the early years in terms of build cost/performance requirements.  Within months of being launched Munslow finished third in his first race, the 2006 Route du Rhum.

Following on from Bolands Mill and a run of production boats built in the UK, our first second generation design with a fabricated steel fin was the Jaz Marine built '40 Degrees' for Peter Harding. Her first outing, indeed regatta  after her launch in 2007 was the Class 40 Mondial/Worlds where she finished second in an extremely competitive fleet, going on to win the 2008 Class Championship before being sold into North America.

Sailing out of Rhode Island and renamed Cutlass, she and her near sister-ship Dragon have dominated the Class 40 scene in the USA between 2009 and 2011 winning the Bermuda Race, Bermuda 1-2, Marblehead-Halifax and the 2011 Atlantic Cup. When fully crewed in particular, Class 40’s are not particularly well rated under IRC which has been a constant battle with RORC since the class’s inception, but they can perform well under PHRF. In the US, Cutlass has won both the Bermuda 1-2 and Marblehead-Halifax overall at the same time as other 40’s have been well presented and spread among the fleet.

Every custom or semi-custom Class 40 that Owen Clarke design is detailed around the wishes and operational requirements of the client. As a first step up to the plate we offer a generic rig, deck, hull, foil, internal general arrangement and engineering package that can be adapted to suit each sailor. An example of this is shown above in the alternate bowsprit and headstay arrangements selected on 40 Degrees and Cinnamon Girl. Individual cockpit layouts also required different solutions to the steering, running backstay and sterns on each of these boats. Our Class 40s can be further optimised to the client’s target races and/or sailing calendar using our VPP and Router race modelling software.

OCD are continuously updating and conducting a tender process with other yards, sail-makers and spar builders worldwide and have a considerable amount of information and costings that allow our boats to be built anywhere in the world. For those sailors and owners who have not commissioned their own boat before we have produced a useful guide describing the design and build process with some frequently asked questions. It shows how an owner goes about commissioning a stock boat or having a custom boat designed – exactly the one you’ve been thinking of.
