The first Sunspirit was a 22' Block Island 'Cowhorn' (Chapelle)or Double Ender (Block Islanders),
*see Chuck's comment below
The boat appeared in Block Island: The Land by Robert M Downie
Spar construction for the more recent, larger Cowhorn, with what looks suspiciously like a Hobbit dwelling in the background.
The larger, newer (building commenced in 1983) boat is a 37' Block Island double-ended cat schooner, built lapstrake with white cedar on black locust.
Living off the grid, in yurts, heating with wood, building traditional boats by traditional methods, using wood felled and milled on his property in Wellfleet, Cape Cod, Chuck Cole is living a life that many of us would envy! (Maybe not all of us.)
I found Chuck on a WoodenBoat thread while searching out info on Christian Neilsen, a Danish traditional boatbuilder and historian. I'm not going to say a lot more other than to refer you to the thread and discover Chuck for yourselves, except to add that in recent email conversation Chuck reports that he's found his ship/mate, Deb, and that they hope to launch the 'cowhorn' sometime in 2010 and to begin cruising more southerly climes. I wish them godspeed in doing so, but not before I can arrange a visit to Wellfleet, maybe for the launch!
