When I talked to the Triak people at the boat show, they said someone recently purchased one to do one of the Watertribe events. It looks like it paddles very well and you can easily remove the mast. I would build an overhead bracket to store the mast when not in use.

It is about 100 lbs all up. and has tracks for it for easy toting:
