    I need to replace the round hatch cover gasket on the bow deck. Can anyone tell me where I might find one?

    That may not be so easy for an original Chris-Craft hatch as it would be for, say, a Bomar.

    http://www.marine-sales.com/ might be a good place to start...

    Porthole Gaskets

    I found at Lowe's weatherstripping that cut lengthwise was a perfect fit for my portholes on my 1964 Roamer.

    Hatch Gasket

    I'm all for using standard construction materials where they work. But if you take a LOT of spray over the bow or heavy rain could cover that gasket, a foam weatherstrip may not be dense enough. Make sure it offers good resistance when dogged down. If you have to squish it (technical jargon) more than 25%, that will shorten it's life.

    If you want marine grade, take a cross section of your gasket to a good marine supplyer. Perko makes a Y shaped hatch gasket in hard rubber which is 1/4" at the bottom and 7/16" at the top (in the West Marine catalog). Hunt Wilde makes a square gasket with a hole thru the center in grey vinyl. It comes in 1/4, 5/16, and 3/8 inch. Sold by the foot. These are in better distributor's catalogs.

    Gasket material ordered

    I found what may be the right gasket material from ERL Commercial Marine, Inc. What I ordered was their .375 HatchPak. I had to order it from TIMCO Industries (812) 945-8988. It is sold by the 5 pound box but they were able to sell me 1 pound (11 ft) for $20.

    After seeing extruded rubber hatch gaskets harden up, stick to the portholes, crack, fail to seal, etc, I started thinking about alternatives. This was also driven by cost, since hollow core 3/8 extruded rubber gasket material, which is what came originally on my Roamer, runs $2-$3/ft and I need about 150'. Anyway, have any of you looked into molded silicone?

    I had this idea about whipping out a wooden mold in the shape of my porthole and hatch seals with a 3/8 router bit, applying release compound, and filling the mold with 2-part silicone that's readily available online. The stuff is relatively cheap (especially if you need to do all of the portholes and hatches, like I do), tough as nails, and shouldn't have any of the problems that rubber gaskets have.

    Thoughts?

    I've never worked with the stuff. Give it a try and let us know how it works. By the way, TIMCO Industries didn't come through, I ordered 3/8" hatch cover gasket and they sent me 3/8" compression packing. I reordered the right stuff from Marine Sales & Repair and they sent me the right stuff. A little costly though.

    This is what I ordered from Mcmaster-Carr. My original had a 1/8" nylon cord insert for extra cushion/compression which I will add to the new material. Order by the foot.
