One more for today:
The J/30 designer Rod Johnstone is in full support of the update-unequivocally. He loves what the class has done to keep the boat current and support his design.
The way I heard it, somebody asked Johnstone, 'If
J/Boats were building a J/30 today would it have Kevlar sails?' to which he said yes. Nobody asked how much this new J/30 would cost, but I'd say $150-200K while old J/30s currently sell for $5-25K.
The J/109 and J/111 do allow carbon and Kevlar, but
J/Boats might consider that their most successful one-design classes remain the J/22, J/24, J/80, J/30 & J/105 all using Dacron mainsails.
