Unfortunately, it sounds bad. You might have water damage beneath the fiberglass on the bridge and have a structural (dry rot) failure as a result. You will need to test the bridge support for water damage. The fix is expensive. You have to replace the damaged structure and re- fiberglass. I agree with Capt Perry that bracing the problem could only be temporary as water seepage further damages the structure.
Until then I would keep the fly bridge weight (ie nunber of people) to a minimum. Sorry............
