Hi there,
The picture of the foam product didn't come through but think I have a pretty good idea.
We had issues with the balsa core softening in the cockpit area between the traveler and the hatchway ... had to drill a bunch of holes and then inject some epoxy to stiffen ... as a result, that part of the deck looked like it had smallpox.
We added the foam over the top and wow, not only did it form perfectly to the space but 1) it's super kind on the knees 2) non-slip enough and 3) has thus far lasted 5 years and still looks great even though it's exposed to the sun everyday. We used a light gray color, 3 or 5 mm thick version, added PSA, does not look dorky at all, negligible weight...not sure why we didn't do this earlier and is awesome.
Hope this helps.
