Pygmy Hatches

[Krusty]

Does anyone have a suggestion on what material to use as a replacement for the foam that seals the hatches on an Arctic Tern?

Not sure of the Pygmy design exactly but on my CLC boat I use this on the through bulkhead hatch. Different widths and thicknesses available but it's all self stick closed cell foam.
