Howdy Jake,
Kudos on the cool artwork.

While it's great to show the vector forces concerning heeling moment and righting moment, it doesn't really tell how these generate forward motion. How 'bout a 3d version that also shows how the force vector from the sail(s) interacts with the hydrodynamic lift from the hulls/foils to produce forward thrust? This might make for a real "busy" diagram, but I just thought I'd throw the idea out.

Just a minor point. The 2d version doesn't show the upward force vector due to bouyancy.

Keep up the great work,
David Ho
