Re: It really pays to research what you need

Are the gaskets on your hatches cracked or just shrunken and no longer sealing?

All four portlights on our boat leaked badly when we got her. I washed each with dish soap and paper towels to remove all the accumulated dirt. Then spent about 10 minutes per seal working Vaseline into the gasket material. Really work it in. Let it sit for another fifteen minutes, then wipe off the excess.

The Vaseline swells the seals and no more leaks. After four years I touched them up again this year with a little Vaseline. Just a quick wipe down this time when one was starting to show a slow drip.

Cost for one of those little travel containers of Vaseline is under $2. I learned this tip years ago to get convertible tops to seal. But if the seals are dried out to the point where they're cracking you're doing new seals.

Cheap, easy and if you find the seals are too far gone you're no worse off than before you started.
