I bought this on ebay in anticipation of my AC project. It is too tall for the cockpit. Is there any advantage to mounting it here to recover the space behind the liner?
Would seem to be overkill, to me. Traditionally, coamings box holes and covers are used (2 each side) behind the settee cushions to access the space behind the liner. The space within generally needs a shelf built to make it useable.
Frank - I also have a surplus 13" x 20" hatch, like yours, that I have been trying to find a place on the boat to use it. I considered the liner behind the sette backrest, but it protrudes too much. Antares suggestion is what most Catalina 25 owners use - the plastic trim rings for the cockpit coaming boxes. Most installations I have seen place the top of the hole 2" below the bottom of the pin rain shown in your photo. The trim rings cost about $8.00 from catalina Direct.
The hardest part of the job is building a floor at the bottom of the space behind the backrest. It is very narrow and hard to get your hands in there to work. One of the guys in our sailing club made his floor from 3/8" plywood, in pieces small enough to fit through the holes, set them in place, and glued them around the edges with thickened epoxy. Once you have the holes cut, trim rings installed, and floor installed, you might want to line the space inside with sheet rubber or outdoor carpet so that hard items you stare in there won't bang on the hull.
The next time I am on my friend's boat, I will shoot some photos of his settee storage, but it probably won't be until March or April.
Interesting that your hatches are too tall. I don't recall the height of the hatch I installed, but I did need to trim the top and bottom edges a little to get the unit to fit. Basicly I just used a sharp edge (open sissors edge) to plane the edge. Once the hatch was installed I used the same technique to blend the cockpit bench to the top edge of the hatch.
