I believe that the basic Volvo Open 70 design has excellent potential, so I would not want to have a completely new design. I also believe that a one-design for the Volvo Ocean Race is right, but providing certain structural minimums are imposed.
There should, for example, be a minimum weight for keel rams, so that designers and manufacturers are relieved of the responsibility of designing something as light as possible.
I would also like to see some laid down specifications for the strength of internal structures and a maximum bulb weight. Stipulating a maximum bulb weight would mean that the weight saved in the bulb could be put into the hull and, in my opinion, that would mean stronger, safer boats.
The Volvo Open 70 concept is good, but it needs the sort of changes to the design principles that I have outlined. As things are, there is too much pressure on designers to tempt them into taking an extreme road.
