Rubicon is our latest 10 Rater design.
The current Mk2 was developed after testing by John Fisher (USA) who is a long time campaigner of our boats.
Waterline length is between 50 and 70mm shorter than on Mk1 depending on displacement.
Beam is moderately narrow at 200mm. This is narrower overall than Rubicon Mk1 but with a similar waterline beam.
Rubicon has the power and the rating to carry a rig large enough to make it competitive against dual rated Marbleheads in light airs.
The underwater sections have become more 'U' shaped to optimise heeled waterline length.
The centres have moved forward, trading forward overhang for effective aft overhang. The deepest point of the bilge is further forward. Hence the forward rocker profile is more steeply inclined with respect to the previous shape and the aft the rocker slope is more horizontal. The concept is to allow the boat to trim bow up slightly when heeled, putting the aft overhang to work whilst maintaining a high forward prismatic coefficient.
Although there are significant differences in the details of the rating rules, there are broad conceptual similarities between Rubicon Mk2 and the last crop of boats to the now defunct International America's Cup Class Rule.
We now offer drawings of the Mk3 boat for the home builder. The hull shape remains very similar whilst the deck and rigs are optimised in line with our current thinking and incorporate some simplified details to make home building easier.
Given the small number of 10 Raters being sold worldwide, we have decided that the minor refinements in design do not warrant new production tooling but individual home builders can take advantage of some small tweaks to the production shape.
We do however apply all the advances in foils, fittings and rigs to our production boats.
This elegant class is still active in small clusters worldwide but the boats are not suitable for everyone as they require more room and 'commitment' due to their large size.

Ten Raters are beautiful, graceful and high-tech boats. If you are lucky enough to live where there is an active fleet, don't hesitate to drop us an email to find out how we can help you to conquer or retain that winning edge...
