The Edon TS515 single scull rowboat is an excellent craft for training and rowing. It has removable pontoons for added security for beginners or in choppy conditions. In addition, the polycarbonate construction makes it nearly impervious to damage compares to fragile fiberglass designs.
I've rowed this all over Houston from Lake Woodlands down to Armond Bayou, it's easy to transport on a car roof with the removable outrigger. Gently used in excellent and fully working condition. Concept 2 oarlocks make it easy to insert the oars. I have Concept 2 carbon fiber collapsible oars available as well for an additional $495.
