I lost my foam transom supports this week-end. You know, the bits of foam you attach to the bottom of the hulls to rig your boat. I stupidly left mine on the trampoline and drove away. They flew out... I retraced the route I took but no avail, they are gone. I'm bummed, those were really nice, the right shape, the right thickness...

Before I order a new set from Stealth Marine (£45), I figure I should investigate how those thing are made as I need some for the 5.2 as well.

Do you know what material are those things made of? Any idea where I could find a source for this material in the UK? How do you cut it?
