Hi Kent and Bill. I checked on Ocean Pearl today and all the hatch seals unquestionably have the large hole in the center

Here’s the site I was looking at.  These are truly half-round with base 1”, height 1/2”(not 1”).

I’ll contact them and Steve’s site to see if I can find 1” x 1” high D profile in neoprene.

Steve, 

Note that Trim-LOC says it uses EPDM Rubber. 

EPDM is related to polyethylene...I assume that this will be similar to polyfoam. The specs state that "compression Rating Recommended 25% compression for the maximum performance." This is where I had a failure with the gasket I previously used. If you notice the weight of the engine room hatch, it will compress the D Gasket to more than 25%, especially if the center hole is large.

Maybe the one that Kent found with a 3/16" hole will be the best.

It will take about 90' to do everything.

Best,
