As seen from earlier posts, I'm working on my roll. I was thinking about trying to roll my Walrus, but I am concerned about the canvas in the pool. Should I just continue with the Arctic Tern, and try rolling the Walrus in the salt water when summer rolls (no pun intended) around? The Walrus fits me tighter, but the spray skirt doesn't fit the coaming very well, so I am bound to get water inside. The inside did not get sealed well, as the Elast-o-Seal did not penetrate the canvas thoroughly.
