My A is competitive on a local or regional scene but would not be competitive on a national or worlds scene. I own a boyer MKIV and prior to that a well built Waterat. I think that putting banana boards on might help the boat sail faster, if it would only improve my sailing abilities as well, I would have the modifications done. With that said, to use banana boards you do need to modify the trunks to the shape of the boards and this could easily be an expensive proccess. I am only guessing, but if I asked Lars to do this modification I am assuming that boards included this could cost between $2,000-$3,000. For me, that is not something that I would want to spend right now on the boat. I though am not sure that I am against this development. Whose boat is using the banana boards?
