I am more worried about the behaviour of the hull in the real world. the multiple chined design is in theory quicker and cheaper to build but it also results in a hull shape that trims very differently when heeled and a plan shape that does not, I feel, represents an easily driven hull. With the appendage design taking months on the current crop of 60's I am sure the rendering just show a possible location and combination of keel, daggerboards and rudder.
It is my opinion that the IMOCA60 rule is a pure development class and I fully agree with Mich Desj who said after winning the 2008-2009 vendee globe that everyone who moaned about the breakages should actually race one of these boats for 90 days straight and then tell if they still feel they are fragile. As it is a development class I cannot see how and why one of these boats will be good for cruising. But again that is personal.
I do think your motoryacht designs look extraordinary and in the appropriate topic will ask some questions on those. |
These renders are really initial sketches before complete design and development. I'm convinced that hard chine requires a complete analysis of appendages, to balance the extra wetted area by a reduced appendage surface. If you visit my webpage, going into RC model section, you will find a concept I'm pushing ahead, mixing round and chined hull in order to create a lifting effect.
Mk-I concept was designed not to meet the higher level of performance, but to meet minimum criteria to enter IMOCA 60 class, and be able to participate to a Vendée Globe. Economic and recycling was the aim of this boat.
Mk-II has been sketched in 1 week only, when we found a potential sponsor with no fund limit, and it has not been developped further since that time. Unfortunately, it was really too late to build and race the ship in acceptable conditions, and we gave back the money.
