WYD,Panel weights haven't changed since version 1 of the rule. Structural requirements have only changed due to the ISO standard going from a draft standard in 2003 to being a final standard for the 2008 race. In the process the standard increased structural requirements in the slamming area slightly. No changes were made for this version from a structural point of view apart from the all up weight increase.
It would be interesting to estimate how the increased panel weight compares to the difference in total hull weight in this version of the rule. My guess is that they added more panel weight than they added hull weight and, as a result, they reduced the amount of structure that could be built. Does anyone have a copy of the V70 Rule from the last go round?
Pat S from FYD had been quoted as saying that there was enough weight available in the rule for the designer to distribute structure with some 'flexibility'. Sorry for the pun. Perhaps he will wish to rethink that comment, but can you comment on it's validity? I work with ISO 12215-5 about every day, and I think that a VO70 must far exceed the rule limit in many areas. It is a fair minimum standard, but created around the idea of production boats, not offshore one-offs.
Steve, you are not serious with the value for VOR in going around with an old boat, are you? Isn't the condition of Sanya enough to convince you of the folly? Noncompetitive an used up, putting it kindly. It would be different if they would initiate two classes as is being done in IMOCA, maybe. Big maybe, because where will the money come from to fill that class? Even with an old boat, the cost of a VOR race is huge. The boat will need a rig, and sails, crew, and new kit to get around the race track at all.
