The Debulator and I are beginning to think about some SOT's to add to the arsenal. Mostly for snorkeling and possibly shallow water diving in the Gulf, but perhaps some swamp stomps where getting out of the boat frequently is needed.
I'm thinking I can make a narrow boat stable with an outrigger more easily than I can make a broad boat faster. Perhaps 14 - 16 foot in length. Fifty pounds or less would be very cool, as we're not getting younger and pulling over logs is a reality in our world. Smooth bottom would be easier in the swamps. I've looked at Eddyline, Hurricane, and RTM.
