Rubicon is our latest 10 Rater design.
The current Mk2 boat was developed after feedback from John Fisher (USA) who is a long time campaigner of our boats.
Overall beam is moderately narrow at 200mm.
This is narrower overall than Rubicon Mk1 but with a similar waterline beam.
The underwater sections have become more 'U' shaped to optimise the heeled waterline length.
The centres have moved forward, trading forward overhang for effective aft overhang.
The deepest point of the bilge is further forward along the waterline.
Hence the forward rocker profile is more steeply inclined with respect to the previous shape and the aft rocker line 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.
Waterline length is between 50 and 70mm shorter than on Mk1 depending on displacement.
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 generated by the now defunct International America's Cup Class Rule.
Rubicon has the power and the rating to carry a rig large enough to be competitive against dual rated Marbleheads in light airs.
We are working on drawings for the Mk3 boat.
The hull shape will remain very similar whilst the deck shape and rigs will be optimised in line with our current thinking.
The last images on this page are of the Mk1 plug being constructed in 2003 inside the Victory Challenge America's Cup Team base in Auckland.
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...
