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

I had the same boat. The solution is to pull the mast cut off several inches and build a new step. It will cost 1500 to 2500 to have a rigger do it. Sorry!

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.

Re: mast step corrosion

Never had an aluminum mast but the engineering is relatively simple methinks. Could you slack the turnbuckles and jack up the mast by.the mast winches or boom fitting and support the weight on a structure on deck while you cut off what's corroded on the hoof and build up whats needed in the bilge to take the weight when done .I'd envision an A frame with a comealong to a rolling hitch on the mast for control but positive blocking while you've got your fingers under it. Measure twice, cut once..
