Inspection Port Fix

This is the worst place to put a deck port on a Hobie (any Hobie), Little Wing is right in that regard. It is not a guarantee that the hull will fail, but it certainly isn't helping things by having a big hole there. There is a lot of load trying to break off the bow in front of the pylon and the structural integrity of the deck is critical.

I would not just start dumping foam, resin, and glass into the hole. You need to take a careful, thought out approach to fixing this if you actually want to reinforce the deck back to original strength. You need to recreate the fiberglass/foam sandwich that was there originally. From your pics, it looks like you're on the right track. Do a good job on this repair and it can be as strong as new.

FYI. Epoxy on Poly Resin will work.
Poly on Epoxy Resin will fail.

Years ago, I repaired a Hobie 14 deck with a similar problem and had great success.

I reinforced that area with an old sail batten turned on it's side, shaped to match the contour of the underside of the deck there and fiberglass it in place. The deck began super strong there. I added two "ribs" about 1 1/2" from the new access port (both forward and behind) spanning the width of the decks' underside to the hull.

This work is easy to do with the boat upside down sitting on sawhorses.
Use curved base access ports and dry fit them first without silicon caulking.
Than remove the ports to give your hand more room and keep the ports clean of new fiberglass.

Let gravity be your friend.

This batten became like a "rib" in an model airplane wing. Rock hard but still light weight.

Yet another hull soft spot caused from using this area as a step

I never step on top of my hulls. But, to raise and lower my mast each time, I have to step up about 33" from my trailer frame onto the front crossbar (and vice-versa). Has anyone found a step that can be mounted on the trailer frame or some other easy way to get up/down off the front of the tramp while the boat is on a trailer?
