I've had Dan make 2 covers, one for a Wenonah Moccasin, and another for my Advantage. Excellent item and Dan will work with the customer to get what they need.
Interesting is how it affected the performance between the 2 canoes. The Moccasin was 15.5 feet, slightly asymetric, 29 inches at the gunwale, straight sided, 0 rocker. The cover transformed how it handled wind and waves making this solo fairly easy to paddle in somewhat nasty conditions. On the Advantage a cover offered little benefit in simmilar conditions, I figure due to the amount of tumblehome in the hull. Either canoe benefited from adding the cover, the effect did vary due to hull design.
