Well fellows, it`s that time, tomorrow I go back home, and I have to fix a few things on "Pestanas" before she goes to work again.
See drawing of the problem I have.
Look at the arrows. The dotted lines are a fiberglass beam ( about 1x3" ) from side to side, and this beam is broken where the arrows point.
My plan so far is:
1. Add a beam fwd of the existing one, with a 2x3 plywood-made beam, embeded in the new fiber-glass. From port to stb inside edges.
2. Add two support poles from the beam, to the cabin sides shelfs top.

Any ideas ?
 
No pics. Can only guess that you have a hardtop ??? and its sagging ??
Hardtops fill up with water the same as a transom. Cut the old rotted wood out and reglass.
Post pics. if you can.
 
Fixed roof sag finally...

After months of thinking of how to easilly/effectively fix the weak sagging roof, ended up fixing it by adding a reinforcement beam, side to side, inside the cabin, bolted to the existing fiberglass/wood beam. I used two, 1"x2" galvanized steel, gauge #14, ornamental steel hollow tube, sandwished together with the original beam with 3/8" bolts.
I lifted the roof with a jack, leveled it, placed supports under the roof, and drilled everything with the roof on its level position. Bolted, tightened, and Bingo !!!, now all straight and solid as it should be. Now we walk on the roof and feels great and secure.
Water now does not collect on the roof of course.
Total cost; about $30
Total time; about 3 hours

I will try to post pictures.

Pictures...

This is how I fixed the roof sagging. Works just wonderfull. Perhaps the only drawback is the weight added to the bow, I guess around 15-20 lbs.

JJ did you fix what caused the problem? I would suspect you were taking water into the laminations of wood from someplace. Hull - cap joint screws in to the top not sealed some accessories mounted on top without sealing well bow pulpit or anchor tie down bolts letting water in.

There are ways of repairing draining it out, drying it out epoxy formulation into the wood (injected) if small area.
 
Willy, that was no easy fix by repairing the existing FB beam.
It broke at the very corners where this side to side beam meets the two fwd-aft beams, under and along the sliding door. It is just a weak design from factory.
Also, glueing and repairing against gravity ( upside down ) is even worse.
The wood inside the beam is still strong, when I drilled it, wood came out clean.
I though about this problem for months, and one day, "the bulb lit".
