Re: mast step corrosion
My Pearson 28 , 1976 has a keel stepped mast which sits in water most of the time. Is there a way of preventing the aluminum mast from corroding other then keeping the area dry.
Thank you. Gary
In a word, no. I've attached a couple of before & after photos of my own mast step to show how bad it can be if you don't take care of it. Incidentally, the mast was already out so it wasn't a very difficult or expensive job but it took quite a few hours to build the new step - epoxy composite with an aluminium step plate. Welding the cruciform locator was the only work I had to farm out.
Oh, as per JSAR, I had to trim 2" of corrosion off the bottom of the spar so built the new step 2" thicker to compensate.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
