A micro-cabin cruiser (a pop-top camper/tent meets a sailboat/shanyboat)

This one's very sparse, and seasonal, in terms of shelter, but I still thought it might appeal to all you tiny house, camper, and even houseboat, fans out there....

My brother, Dustin, sent it my way...he'll be part of our 2011 Relaxshacks.com Hands-on, Tiny Shelter Building Workshop on July 9th as well.
