Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: 15' Sport Hatch Cover

The hatch cover on my 1985 15' Sport model is delaminating. Instead of using the mahogany plywood that the factory originally used, I was thinking of making a hatch cover similar to the one on the 17' Montauk, out of either monogamy or teak. Any thoughts on this?

Is there a way of keeping the plywood cover looking good without refinishing every 4-5 years? I have the capability of making a cover ala 17' Montauk, (Resorsinal glued strips, with end boards covering end cuts).

Thanks for any advise to can give!

Consider a teak hatch cover like the one on my 1987 Montauk.

You could fabricate it or have Blackduck make one for you.

If you think maintaining the cover every 4-5 years is a problem you definitely want a teak cover like Phil showed you. It is the only material that will hold up, and it is a design that doesn't need to be improved on.

That doesn't exactly match the rest of your interior so why not just make a new cover out of plywood? I know the old one only lasted 30 years but I can make a lot of plywood covers for the price of a teak one.

Phil,

Thanks! I was hoping I would get a picture of it!!

I'll put a 45 degree rout on each of the interior boards, glue up with resorcinol.

Great personal page!!!

Art -

The boards are not glued together, rather there are two batten boards on the interior side.

This shows the top batten

Phil,

WOW, this makes it a lot easier to build. I thought I would have to run the boards through a shaper to put a tongue & groove to hold the boards together. Are the center boards loose and held together with only the backside cleats?

Is there also the V groove on the surface where the boards meet? If so, a shallow 45 degree rout would achieve this look. It looks like the top and bottom end boards were glued and screwed. Is this correct?

Thanks for the inside shot of the hatch cover.

I got tired of constantly fixing / replacing mine. I ended up replacing it with a solid piece black starboard. It looks good andshouldl last forever.

Blackduck made mine. Excellent craftsmanship.

While my cover was never apart, I would imagine the boards were just screwed together. I did not see any dried glue on the top strip when I repaired it.

The V is not the thickness of the board, rather just at the edge, less than 1/2 the depth.

I made this hatch for my 1984 15' Sport CC, after disassembling the hatch from a 1985 Montauk as a reference. The wood was called "red mahogany" at my local hardwood store. I encased it in epoxy & finished with 5 coats of varnish. The finish is a bit wavy...

I've attached a photo.

I also have a SketchUp model that shows some dimensions. The model is missing a few faces, but I think you can get rough dimensions and other info. I cannot remember if I tweaked sizing as I went along, so use at your own risk.

Understood. Email me for the model if it is of value to you.
