I did about the same thing but what I found is that the bolt that goes through the whole end up pinching against the fiberglass and putting pressure on it sideways not laterally. This caused a couple small spider cracks that I didn't think would happen with the amount of reinforcing that I didOn my old rinker that I added the tower myself I used 3/4" king star board as reinforcement. I shaped it as close as i could with a table saw and belt sander. then stuck it to the inside with a bunch of 3M 5200. it was rock solid and will never rot.
Not sure what you mean here. Never had a problem with mine. No cracks at all.I did about the same thing but what I found is that the bolt that goes through the whole end up pinching against the fiberglass and putting pressure on it sideways not laterally.

basically I am saying the fiberglass of the hull itself is just a little thin if it wasn't a factory tower. Even with my backing board and epoxy reinforcement I feel the hull has too much flex. When I took it apart a couple years ago to redo it and make it beefier (original kit that came with tower had marine plywood) the threads of the bolts had pushed into the fiberglass with forward/backwards motion that they kept an imprint of the threads. I have a couple spider cracks as well.Not sure what you mean here. Never had a problem with mine. No cracks at all.
