I had some quality computer time today, and read up on some interesting C-class litterature.

One was an article saying that upwind about 36% of total drag came from the platform moving trough the wind. One of the worst structures with regards to drag is circular tubes, so perhaps the spi halyard and extra rigging really are responsible for 2.5% performance loss to windward. Perhaps it's time to streamline those bowsprit stays and route the spi halyard down the forestay (or inside the mast)

Except for the A2 A-class, most hull designs look like they have not considered drag as they pass trough the air. The same for crossbeams (except those boats using wing-mast sections as beams). While I am thinking along these lines, I think I need to work on my own body so I can get a better aerodynamically shape to my "behind" <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
