Hello fellow 18.5 owners. I am looking to reinstall missing wooden hatch guides on either side of the sliding hatch (on top of the deck) over the companionway. The current owner of the boat I am purchasing took these wooden guides off the boat (I guess it was easier than refinishing the wood). At any rate, the guides are flat, maybe around 18" long, 3" wide and about 1/2" thick made out of teak. They are held down by screws. If you could, I need to know the actual size of these guides to see if I can either fabricate them myself, or purchase them. Thanks!
