Thanks for the suggestions Twisley. At least for now I think I'll go without the sliding-seat rowing system. My primary interest is cruising, and what to do with the sliding seat gear while sailing seems problematic. I've made some repairs and minor modifications to the boat as well as making a tent for sleeping aboard. Had a nice first overnight cruise in the Parker River National Wildlife Refuge area (Plum Island Sound, from Newburyport, MA). I've enjoyed the pictures of your boat, and would include some of mine if I could figure out how to do it . . .
