Bob,

I'm with you. I am (obviously) a big fan of the Performance product, but the way they've handled model, a.k.a. class, changes is terrible. What you describe is by far the worst yet. I'll conceed that a product line should be allowed to mature occasionally so that the boat and/or manufacturer can stay competative in the market - but this list of sweeping performance altering changes are asking a lot. I would expect this kind of change out of the F18 product but not a well established class like the I17.

Do the class members get to vote on any of these changes? I can understand why Performance Catamarans might want to insist on a change like the trampoline (easier production methods with minimal performance enhancement) but things like an optional spinnaker size, minimum hull weight, etc. should be brought to a vote.

It isn't a "Formula" class if there's only one to choose from.
