Strengthening the cabin top

I am coming to an exciting milestone in the rebuilding of Windsong: deconstruction is nearly complete and now repairs and upgrades can begin! I need to get my plan in line for the following projects before I start painting the decks:

Cabin top stiffeners/supports
Bulkhead repair/replacements
Compression post repair/replacements
Plans for the large windows
Healiner replacement

First off is to improve the cabin tops and get them secure before I start painting the decks. In the process of deconstruction I removed all of the old stiffeners on the cabin tops, all of the old compression posts, and windows. With all of those gone, the cabin top sagged alarmingly and flexes a bunch when walked on (which I try to avoid). I’ve put up some temporary compression posts to support it while I am working and they seem to do a decent job. I want these repairs finished before priming and painting the decks since extra flexing would probably distort a good paint job.

The old stiffeners were molded and gelcoated fiberglass “box” shaped stringers with a teak beam as trim and molded in bases for dome lights. These were screwed into the cabin top and glued with some thickened resin. Once the screws were removed, the glue separated pretty easily and removal wasn’t much of an issue. These pictures show what the stiffeners looked like before I tore everything apart. I don’t have many pictures of just the ceiling, so just look at the top to figure out what I’m talking about.







I may re-use the old ones since they are already sized for the boat, but would add a few layers of glass on the edges to permanently secure them to the cabin top. However, I am not too keen on the molded light bases, which would make my headliner paneling difficult to cut. An alternative would be to glass in some lower profile stiffeners in the same spots as the old ones, using something like cardboard tube or shaped foam as a base then glassing them in. Then I could attach my overhead panels to these and use the old teak trim from the original stiffeners to hide the seams of the panels.
Here is what the cabin top looks like now, bare:









I have options written here, but if you know of something I haven't thought of or have any experience with these upgrades/repairs please chyme in.
