Sweet! We should totally start a club for sailors over 6'5"! I am 6'8" so this is an issue that is near and dear to me. Power Boat? For shame!!
My last boat was a Hunter 37 Cherubini that had 6'6" of headroom and that little bit of bending over drove me nuts over the year I cruised in it. My current boat is an 41' Seawolf and it has 7' of headroom. What a difference! (See also CT, Island Trader, all the same boats different names). Mason 43 and 44 although expensive also have 7' of headroom.
