Thanks, Wouter and Mary.
I may try the pool noodle or gunwhale bumper idea but I think I'd prefer the purpose built stern rests. I'm worried that shipping from overseas will be prohibitive unless I could get them sent with someones boat in a container. Maybe it would be less expensive to just have them made at a foam shop. I'm surprised they're not available in the US! Sounds like something that Online Marine Store at Cat Sailor would sell a bunch of (hint)! Wouter, if it's no trouble, I'd appreciate if you could post the sources you know of. I think I've heard you can get them from AHPC but I don't know if those would fit other boats such as my current H17 or the Blade. By the way, do you know if Matt sells them for the Blade? Thanks!
