Just curious how old is your boat
Only reason I ask is to see how long the plywood hatch
lasted and is plywood
a viable option for the base of a new hatch
? Ply could work
, but when out in the weather
, will eventually rot
Don't know if you are handy, but you could make a new one.
I like the idea of a f/g base instead of ply, then glue your old teak
on top to maintain the appearance. Not too hard if you make a mold
out of thin ply and curved wood
to match the crown in your hatch. Apply a mold
release agent to the ply, then start laying in f/g and resin until you have a sufficient base for your hatch. (Make it a little larger than original size so you can cut it back to remove rough edges)
Can't see the hardware
for the slider portion, but most likely could reuse that hardware
then mount on the new f/g hatch. Clean up you old teak (remove glue/ply stuck to bottom) and glue on top of f/g.
Attached is a pic of a similar style sliding hatch that we built.
