I need the hardware below the deck as the hatches are smack in the walkway. I can accomodate anything for that; including lowering the deck level at the hardware.

Devil is in the details.

I could also do with the 22x18s; especially if the hinges are on the 22.

Thanks! Super big help I hope.

Well, folks, I must say, these hatches are a mystery. It looks like I will be making my own and probably using plywood so they are stiff enough to walk on and hold hardware. …. or perhaps corelite board

gotta start looking for build it advice now, I am running out of options..

I'm going to attempt to build my own soon. Working on a mold now. I'll be using gemlux flush mount hinges. They are swagger down, and have a finishes edge, so they only stick up like 1/16" or so.

I just ordered 3 sets from Gemlux.

I am going to make guttered hatches probably 1/2" plywood lids on corelite guttering.

The profile and where to gasket is a mystery to me.

One is a livewell, gutter is draining to well.

The others are going to be guttered to the edges; inboard.

I made a mold and I'm hoping it works. I made these to accept a 3/8" cored lid. The gutters will be 3/4" deep overall.

The big flat area in the middle will be cut out at the edge creating a finishes edge inside. The 2 bigger corners will have 1/2" drain tubes I made so I can run the water to my motor well.

Are you going to gasket the base?

I was thinking black latex tubing. 1/4" od, 1/16 wall 1/8" id

There is a 3/16" id with thinner wall, but nervous it'll fail sooner.

Then I'd run a round bit 1/4" od 1/8 down and contact glue it in.

Any opinion on the sizing of the gasket? 10' is like 17 bux and it isn't enough...

Also; how are you going to build to that mould? The sharp 90 has me confused a bit is all.

The stainless steel t-nuts that I am using on the inside of my plywood hatches would work great for your fiberglass hatches.

I drew a mockup of a gutter and cover system and we did a little experimenting.

I don't like this design as the gutters are a bit deep amd the corelite gets pretty heavy..

I redrew it roughly and my new plan will get a picture and good draw tomorrow.

I can't upload a picture.... :doh:

At least one of my hatches is a rare use version that I could have actually just screwed down. I purchased hardware already for it.

Can you explain what you mean? I might actually prefer screwing some lids in place. They would be less obvious for criminals to steal from if they didn't look like common use hatches. Then I could hide fishing tackle in them, etc.
