I am considering moving up to a H35.5. I presently own a 1990 H30 which is very similar in profile and layout but doesn't have quite as much elbow room in some areas and about the same in other areas. The chief advantages to the 35.5 over the H30 seems to be the 3 cylinder diesel and PHRF of 132-138 instead of 189-195. I also sail in a light air area which I would hope the lower PHRF numbers of the 35.5 would come into play. Any and all comments would be welcome or I can be emailed at gm18sail@aol.com.
