Thanks, Sundance. According to some of the sites, the genoa is 135%, but according to my calculations, the current one is more than 150%. Odd – my measuring of the boat’s J dimension makes it 2.67m (hence my calculation of 150%) but the stated J dimension for the Bav 30 is 3.1m – odd again.

Anyway, I’ve had long chats with the sailmaker, and taken your advice about foam inserts. Couldn’t quite stretch to Polyvant, but we’ll have a better grade of Dacron than was used by Elvstrom. And yes, we WILL have UV protective strips!

Interesting about jib rather than genoa, CaSam: might make for easier handling and better balance, I guess.
