Question Displacement or plane hull?

I know that I'm going to get an earful on this: Which is better for offshore cruising? A displacement hull or a planing hull?

I'm drawing up sketches for a potential build and currently the prismatic coef is 0.65 -- right between a displacement and planing hull. It would be nice to be able to get the hull up on plane, but I'm concerned that it will be a pounder in rougher water and slow in light winds. On the other hand, the potential planing speed sure looks nice when facing a long trip. I suspect that having the pc at 0.65 will yield a hull that sucks at both.


stats: LWL: 33.5', LOA: 37', Displacement: 13500, Beam (waterline): 9.7', Beam:11.5', Sloop rigged.
