Hello all, I'm a former Laser owner and have decided to get back into it by purchasing a relatively lightly used 1978 vintage Laser. Interestingly, it's about the same age as the boat that I used to sail some years ago. I have been reading a lot of posts about the mast step, and I'm preparing to do some reinforcement work. The mast step has no visible external damage and does hold water. There is an inspection port. Here is a picture of the "donut" area. As you can see, there is a piece missing (which I have located), and there is also a loose piece to the right of the missing one. Other than being a bit dirty, everything else in this area seems to be quite solid. I'd like some advice on dealing with the existing "donut". Would it make sense to replace the missing piece and glue it back together with 5200 or epoxy? Or, is it best to remove (chip out) the entire donut and fill the space with epoxy? Once I deal with the donut, I am planning on adding glass and epoxy down the mast cylinder and onto the hull as I have seen in other posts. Any other suggestions are welcome. Thanks!
