The other problem I had was the front shroud mounts, they always came loose after a few days of sailing and the plates moved away from the hull about a millimetre each time. The screws never seemed to tighten up full and I was hesitant on over doing them incase I stripped them thus causing more headaches !!!!
I did get some relief when I put resin into the screw holes and then add the screws, it did firm up considerably but there was always that gap that kept coming back.....

me thinks this may be the cause......
obviously there's been a past issue too !!!
