Re: Triton mast beam attached how?

The two bolts keep the mast step from trying to slide around on the deck when stepping the mast, or if your break a shroud.

I would put them back, but overbore the holes in the mast beam and fill them with thickened epoxy to reduce the chance of rotting out the new beam.

You can do it, but you'll want a pad eye on the deck or cabin side to bring the block in from the rail with a big genoa to get some sheeting angle back, where the line runs up to the block and back down to the rail with a fixed eye or loop in the center.

Re: Coronado 15 project.

Have you tried POR15?

It is ridiculously tough paint for the underbody of cars, and wants a layer of flash rust to bond to. You can't break it beating it with a hammer, nor chip it off.
