Help!......cracked mast

Jan 31, 2013

I finally finished my fiberglass and restripe project and got the boat all ready for the season. As I was raising the mast, I cracked the reinforcement plate and about 1/2 inch of the mast. Picture one is with the reinforcement plate on the mast and picture two is with it off. About a 1/2 inch of the original weld in the mast separated. What do you guys recommend?

I was thinking about having a welder weld the mast back into place and attaching a stainless steel collar for strength. I would also cover up that hole and raise the mast using an alternate and less stressfull (for the mast and myself) way.

Any suggestions?

needs to be an aluminum reinforcement, ss will corrode the aluminum away from underneath it. have the guy re-weld the seam and do a pipe scarf over the top of it.

Rufus is right on.. If you have internal halyards, make sure the inside is smooth after the welding. That looks like it could be re-used as well.. if it is aluminum..

I have never been a fan of rewelding aluminum due to loss of structural integrity and suggested a new mast when the mast is split like that. Although the above suggestion is an alternative, the decision will be up to you. The mast was a Z Spar and now U. s. Spars.

What I ended up doing is have an aluminum shop fabricate a heavier duty aluminum sleeve that braces more of the mast (approx 12 inches).

Although that is good I am still worried about the crack in the front of the mast that could very well elongate. Just keep a close eye on that sir.

have the welder stop drill that crack and then reweld the crack in the mast ...if they clean the aluminum with a fine grinding disk and ss wire wheel and tig weld it .... it will be fine and use 4043 alloy filler metal
