One other thing. I'm not sure how long you've had your boat, besides the normal things you look at for maintance check the shroud anchors. This is the eye that comes up through the hull. The shroud is attached to it. Unscrew it all the way and look closely at it. I had to replace these things yearly. It would tear in half. I had one break and found a few over the years several that had cracks.
I second that. Two years ago we dismasted during a race when one of those let go. The bolt had rusted through.
