. Unfortunately, they don't work on the hull of his new boat (X10--I can't find smaller suction cups, so we had to buy Nauticurl Flex), but they work very well on my SV211. I've added dimples to the face of one, like the Swell H3X--not sure if it makes a difference, but it didn't cost me anything to try.Rather than cutting boards, I just buy 1/2" HDPE. The suctions are from Harbor Freight. They occasionally break, but they're only like $8, so I just keep spare parts in the boat. I think they end up costing < $25 total (plus a couple hours of work).
Just wanted resurrect this thread to share my design.
