I once installed teak coaming trim rings on old sailboat years ago by cutting out the opening in the coaming, glassing in a ply shelf so it would drain to a couple of 1/4" drain holes, and fitting the prefab teak trim rings in place, it makes great stowage for winch handles, hats, etc. Now with my Hunter 33 I want to do the same thing, but I can't locate the trim rings, anyone know about or have the source for these?
