Re: Starboard rear hatches on a 20
 

Its fine if its backed by something and has enough support and is screw down. how big do you need them to be? I might have 2 scrap peices of marine ply I can cut to size for you. coat with epoxy twice, sand and paint. they will last 10 years. let me know what size and I can measure what I have left over from the latest project(full composite floor in 21 mako).

Thanks but I'm good. I already started on the hatches, plywood, s-glass, epoxy

Re: Starboard rear hatches on a 20
 

I replaced the three rear hatches on my 20 with 3/4" Starboard in 2003 . It matched the thickness of the warped wood that was there previously. There's been zero warping.

Wood, otoh, you can count on warping if it's perpetually damp on the inside, like a bilge, bait well or cooler.

Re: Starboard rear hatches on a 20
 

I started other hatches already, if i had done the starboard i was going to do it out of 3/4" and just route from outside in a 1/4" deep to recess to hatch but leave the center 3/4" to give it some meat.
