Summer Upgrades—Hatch Work

The Lewmar size 3 hatch over our galley sink needed replacing. I’m fine putting new seals and O–rings in an old hatch if that’s all that’s needed to stop a leak. You can get the parts at Hatchmasters. But in addition to dripping water down the back of our necks while standing at the galley sink whenever it rained, the hinge rivets broke off this one, so the hatch wouldn’t operate properly, and replacement rivets are impossible to find. It needed to be replaced.

In another case of procrastination paying off (I wouldn’t keep doing it if I didn’t get so much positive reinforcement), West Marine put all their Lewmar hatches on sale, and for a brief period were actually the cheapest source I could find for a replacement. The price was so good that I bought two, although being a somewhat rare size, it took them two weeks to get the new ones in.

The replacement hatch had been redesigned to eliminate the hinge that had broken off our old one, which I liked. One less thing to go wrong.

It fought me tooth and nail, but I eventually got the old hatch out with the help of some heavy duty pry bars from Harbor Freight. Then I cleaned and prepped the deck.

If you follow us here at Life On The Hook™, you know that butyl rubber tape is the only bedding compound we ever use. But don’t use just any butyl rubber tape from Home Depot or AutoZone. Get it from this guy: http://www.pbase.com/mainecruising/butyl_tape. His is the best.

I applied several overlapping layers of tape to the flange of the new hatch.

Then all I had to do was set the new hatch in place, press it down firmly to set the butyl tape, tighten the mounting screws, trim off the excess butyl that squeezed out, and I was ready for a leak check.

I’m delighted to say that we no longer have to endure the shock of cold water dripping on our necks while washing dishes during a thunderstorm!
