This past weekend hubby and I took a few kayaks to the lake for some folks to try out before they put down money on some for themselves.
One gal tried our Necky Manitou 14 and then the OT Castine. She found, due to her hip shape, the Castine was a much better fit and more comfortable for her. Her husband paddles a different brand 12 footer, which she also says doesn't fit her body type.
This is why experienced paddlers recommend you TRY BEFORE YOU BUY, if possible.
I am not a canoeist, though we have an old aluminum Grumman, so I can't say if the same is true for that type of boat. Canoeists would have to chime in on this topic for fit.
