Need to replace the front hatch cover. What type of wood was this, lookes like a mahogany veneer plywood? Also the ends appeared to have a kerf, purhaps for some type of molding or weatherstripping? Any info. or reccomendations for replacement would be helpful. Have the wooden handles and they can be re-used as they are in good shape un-like the hatch. Besides the price differences would using solid wood be better than plywood, also would teak be a better choice to up-grade? Also any ideas on weatherstripping, was this original? How was a close fit maintained to keep in place , or is this supposed to have some "play or le-way" in fit? Not trying to re-invent the wheel so to speak, but would something like 1/4" o-ring wrapped around peremitter of hatch help? This could probably be inserted into a kerf if milled into sides of cover.

Thanks,
Kevin

Howdy '63.

You don't say what Whaler you are working on, but you have figured out the original configuration.

3/4" mahogany veneer marine plywood. The kerf held a rubber strip to make a press fit and water seal.

Because that plywood is so hard to find most guys make new ones out of solid mahog, but it is very difficult to get them perfectly flat and to stay that way. Most of them warp.

Correctly placed gussets on the underside minimize the warping.

My 15CC had whalerboard fabricated for the bow locker (badly). I used oak (YES!) veneered plywood, stained it red mahogany, and with a lot of sanding and varnishing, it looks and acts like mahogany - and, it doesn't warp ! I can e-mail a pic if you like.

I made a hatch cover for my Sport 15 with solid 3/4" mahogany by using 5" planks. I trued the edges, biscuited them and glued them up alternating the grain on each plank. On the underside, I used 3 1x1" mahogany straps across and glued and screwed them. Then I applied I think 7 coats of marine-grade poly to everything. No warpage yet (9 years later).

I have a 1978 V20. Were the original hatch covers made of mahogany or teak? I would like to replace the existing painted plywood hatches and want to know what to look for and any problems.

Hi, Jay.

The original was teak.
