How Do I Make It Stick?

I am trying to put a shelf in my lazerette that needs to hold approx 80lbs of stuff. Of course, on the outboard side is the hull and on the inboard side is an interior bulkhead. I want to put wooden supports on both sides to hold the shelf. Would 3M 4200FC work? And, how would I hold it in place until it cured enough to use. How much do I apply to each piece?
One suggestion that I got was to put a small piece of plywood on the hull side at each attachment point with 4200 and then I could screw into that with the larger support piece but I don't see how that adds any strength and why not just put the support piece directly on with the 4200?
Suggestions appreciated.

I don't think you want to use 4200....

"3Mô Marine Fast Cure 4200 Adhesive Sealant One part general purpose polyurethane reacts chemically with moisture for flexible bonds to wood, fiberglass, gelcoat, plastic and metals. Forms a watertight seal on joints and boat hardware above and below the waterline. Formulated to allow for disassembly of parts."

5200 won't cut it either, it's just a faster curing version of 4200.

I'm not a structural engineer but I think you'd be best to use epoxy and a little bit of fiberglass especially with a shelf that has to hold that much weight. Just my $0.02 worth.

And make sure you grind to expose glass and wash with acetone. Pita but only way to do it right

Get the West System guide book or something equivalent...

and read up a bit. There is really too much information to put into a few posts. However, if it is a simple shelf, the easiest way might be...
* Clean as above.
* Bond a wooden cleat (3/4" x 1 1/2" strip the depth of the shelf) to the wall. Do this with thickened epoxy (thin epoxy will not match the rough surface well). West system is good, with thickener. Common 5-minute epoxy will work too for something like this, thickened with perlite paint additive. Hold in place with 2 small counter sunk screws for 24 hours. The need only be long enough to go through the first layers of glass, just enough to hold it for clamping (brass or ss). Coat the cleat with epoxy while you are at it.
* For bonding, the epoxy should be thickened to a thick jelly consistency, just barely runny.
* Even with a cored hull, it should not be required to add more material to distribute the load. The cleat will be well bonded.
* Drop your shelf on and screw down. Whether you epoxy or paint the wooden shelf is your call. Much depends on how wet the area is.

Removable and permanent, both.

What do you intend to store there? wont it shift as the boat heels? Lazarretes are a PITA, but I pretty much found using those heavy duty plastic milk crates and sliding shifting them around works pretty well, even when stacked 2 high....although a PITA for sure.
