I'm building a bow hatch cover for my 15 Sport restoration project. I plan to laminate three boards (mahogoney) to get proper width, what is best glue to use for marine purpose?

System-Three, T-88 epoxy.

Although I'd use epoxy as a first choice, Titebond III is a good alternative if you don't want to invest in an epoxy kit for one small project.

you can actually get West System epoxy in a small amount, they call it a repair kit:

What's wrong with polyurethane ("Gorilla") glue?
But Boston Whaler never made bow locker covers that way, They either used a sheet of 3/4" teak or mahogany marine plywood, or made up the cover from a series of individual teak boards, 45 degree champhered egdes, with screwed-in 1" blocking on the underside.

Both type of covers are available ready-made from the Whaler wood guys on this site.

Here is another Whaler locker cover, made the same way, from 3 non-laminated individual boards:

I'll second Titebond III as an excellent waterproof wood glue. It is a common choice for outdoor furniture. Epoxy is a great choice too but it is messy to work with.

There isn't really a problem with Gorilla Glue - I used it to laminate up both of the bow pulpits I've made for my boats. The only challenge is getting the hang of using enough for strong coverage with no gaps in the glue/seam but not so much that you have a oozing foamy mess. If your plans will include a lot of sanding to the top and bottom of the cover, then go ahead and use Gorilla Glue...otherwise, I recommend some other epoxy (non-expanding variety) and enhance the structural integrity with blocks and screws, as Larry indicates was used with the original setup.

Gorilla Glue used on Whaler wood will be the strongest part of the wood, it will never fail along that seam again, may crack somewhere else. Crues via moisture best to dampen surfaces before setup.

Nobody mentioned "Weldwood Plastic Resin Glue"
Many years ago I asked a maker of laminated bent shaft canoe paddles what glue he preferred. The Weldwood is Mil-Spec rated and is only restricted from prolonged steam exposure. It's easy to work with,long pot life, high bonding strength, and very water resistant. I use it for all wood assemblies that will be exposed to moisture.

Get yourself a good supply of West System Epoxy resin with a couple different hardeners-you will not know how you survived without it, especially if you do any amount of work on your boat or around the house.
Mix it up as recommended for one of the best bonds for any wood; thicken it to fill screw holes; use clear hardener to apply as first coat before varnish....and on and on. It is easy to mix and will keep for years.

Larry, I'm trying to copy the bow hatch cover that's on your Montauk, a piece of art. I assumed you built it, if not mind telling me where you bought it
