An optimized HP would look like the ex40. 

  Sitting headroom over the bunks/settees/tables, standing headroom down by the galley and in the head, nicely curved surfaces and minimal cross section to cut down on frontal drag when heading to windward.  And given the sail area and the easily driven hulls, even a beam reach ends up being a sail to windward at most wind speeds (apparent wind noticeably forward of the beam).

  Not that I'm biased.

Looking at the C50 and C60.

Imagining the wind over the WW hull, at all the expected points of sail.

What would an aerodynamic optimized HP cabin look like? With a reasonable cabin volume as an additional constraint.

If one weighted the optimization for most typical points of sail, how would that change?

If there has already been a prior discussion, please point me at it.
