You question regarding data from Zandvoort can be answered. This info is fact, not fiction or opinion.
Average weight of the cat rigged boats was 109kgs Average weight of the sloop rigged boats was 112kgs
I have included the 2007 VMW boats, the 2007 FCA boat, the 2007 Ned boats & the 2007 Stealths - all boats that are relevant to the discussion.
From a munufacturers point of view, our boat weighed 110.7kgs at the event & we have found 4kgs in savings since the event & looking for the last couple of kgs without compromising integrity or using exotics.
Therefore I guess the question has been answered.?
