An Annapolis Wherry looks like a nice sliding seat rower. Now, I've had 18' canoes before and loading them onto and off of the cartop is cumbersome. A 65 lb wheery could be dangerous to load onto a cartop in a wind. What compromises would be encountered if the wheery were built as two nestling hulls? Two 9' hulls would be easy to put into a pickup bed, and easier to store in the garage. Your knowledgeable replies are appreciated.
