I wasn't saying going out in big winds Paul, I'm only just comming to terms with that myself with the 5.8. It sounds like you have it stored mast up. As a temporary solution you could take some foam only a couple of inches thick and push it in the top of the mast so it cuts to shape then sikiflex it in place covering the top of the foam, it would be ready in about an hour, if you do it as soon as you get there by the time you leave the beach you'll be right. Thats far from ideal but will give you time to right the boat, there are a lot of threads on this forum if you search mast sealing. There must be someone else with the same boat reading this thread come on guys what about some more ideas.
