I currently row a fiberglass skiff and recreational,shell for regular exercise and am partial to their sliding seats. I am considering adding one of these lovely CLC woodies to my quiver, and the NE Dory has caught my eye. I am seeking comments from someone who has experience with this  model. . Also if built with this configuration can it be quickly flipped back to fixed seat rowing.?  I am a moderately fit senior typically rowing a couple of hours at a time on the lake I have a cabin .
