Hi Steve,
Surprisingly it would appear that the centreboards beams etc. are in aprox. the right positions.As I am taking about 8" of the back of the boat and about 11" of the front, [overall F16 length 5m. is actualy almost 16'5"]this takes the least volume out of the hulls, the bows will be fuller than A-class and have a round rather than a knife edge stem. This leaves the boat with the front beam further back than a mossie [more bow has to be good?]then the centre boards are further back than a mossie to. Currently as a A-class the mast has quite a bit of rake so even if I have to put a longer boom on to fit F16 sail area. I have room to stand the mast more upright to balance up the weatherhelm. In theory it all looks good. In fact I have worked out a formula, I am sure some math brain can give me the values for. Aclass-L+W-M/H+Sm2=F16 As for pictures I will have to wait till Tim gets back from holidays to use his digital camera.
Regards
Gary.
