Newpport brand woodstove for a Tiny Home. It keeps a small space warm even in Vermont winters. Might work for SD winters too. You could just about afford split wood for it for the winter. :) might even be able to heat a small pot of water on it
Escargot designed by Phillip Thiel. This was originally designed as a pedal powered canal boat for the canals of England. It has been updated since. The Cabin roof was raised 6 inches and it was given provisions for a small outboard motor.
Dan Roeder built a very nice tent for his Wayfarer. Of particular interest are the web girdle strip he runs around the boat below the gunwales as attachment points for the tent and the slide buckles for the webbing attaching the tent to the girdle strip to easily keep it taut. Nice work.
