i don't know about watson canoes, but i think this model is made using fiberglass. $600 is an awful lot to pay for a used fiberglass canoe. they do not handle shock well and can crack if they hit a rock. also, be careful because these canoes are easy to repair and the repairs are easy to hide too. i wouldn't buy this canoe without testing it on the water first, which may or may not be feasible.
