Wouter,
Lets first see when we'll have an Alter Cup event on supplied A-cats, shall we ?
Actually, Nacra was asked if they would provide A2's for Alter Cup, but the $5000 offered is no where near the cost, considering the market for used A2's (I know, because mine was purchased used). When you look at all the A-Cat manufacturers, I think that the Alter Cup had the best chance with Nacra, but maybe you could ask Vectorwerks, since you seem to be closely tied with them, if they are interested is supplying the Bim XJ. I think Jake would jump at the chance to have the XJ as an Alter Cup boat. What do you think, Jake? Would you be interested in having XJ's for your next Alter Cup?
Or a better question might be, How many of you out there would be willing to pay List price minus $500 for a nearly new A-Class that was only used at Alter Cup? Of course, these boats would not have the rig and sail customized for you, but you would save $500 and be able to pick it up at the Alter Cup site, fully assembled.
