Cliff,
The deep keel that was offered for the 35 was a poor design with an even worse production. I bought my boat originally without regard to the keel. Only later did I realize my mistake. Mother nature stepped in and I wound up with my current keel. One lucky break for me. We designed it for quicker acceleration out of tacks with minimal affect on top speed. Anyway, every time I start drooling over some 'hot' boat I remember my PHRF and just can't make the move.
