Yes it works pretty well. It’s approximately 4.6kg helps to carry through the patches and also stops it stalling on tacks. It is just about capable of keeping up with DF 95s and much quicker than 65s in most conditions and very good to windward.
It is from an existing mould, so it is what it is . A shallower angle on the fin would be even better, as would a better shaped skeg but I didn’t want the extra work required.
