hi gary,

I think hopes are always more ambitious than what reality offers it. while it definitely would be interesting to get an idea which design or mainsail etc. is doing better in what kind of conditions, its very difficult to say from these races. you never know performance is based on the sailor and which degree can be related to the vessel itself.
you need high competitive proven sailors, a reasonable number of boats, a course with constant wind conditions not to much surprisingly favouring one side etc...

From that point of view it makes perfect sense to give a statement in a F18 worldchampionship, an A-class worlds, olympic tornado sailing etc... but these 'just for fun' sailing events will never offer a clear view of what the boats are capable of...

regarding the nice singapore event [if you came for fun] they had a strange idea of doing le-mans like beach starts where your starting position on the beach towards the first mark was quite crucial and chosen by a lottery system... so how much can you still talk of a serious race with such a starting system? than the sailors were quite different skilled, so pretty sure the final outcomes much more gave an impression of the crew strenghths than any conclusion about boat design...
