Because a fairly large segment of our readership has expressed interest in ablue-water trailerable' sailboat, a PS subscriber shares here the philosophy and plans for just such a boat. In fact, he's building one now.
The arithmetic of weights and displacements prevents us from ever realizing a trailerable boat that will sail at the preferred half-submerged condition of our hypothetical craft. But you can get a trailerable hull by this scheme that will sail about one-third submerged, which probably is close enough, and that boat will have more than enough righting moment for reasonable sail-carrying. You also can get a boat that weighs relatively little out of the water compared to its displacement in the water--exactly the characteristic you want in a blue-water trailer sailer. I describe this design as "Ultra Water Ballasted."
