Straightening a Mast

Post by Seapup »

Had a Mac 22 buddy meeting me on the water call and say he had an problem...caught a shroud on the way out of the marina. It pulled the spreader straight back and bent the mast into an S shape with extreme tension on one side and the other hanging slack. It didn't look good but wasn't kinked. I had doubts but being optimistic said we could probably fix it. We went back early this morning and took the mast off to give it a try. I think to amusement and slight disappointment of the live aboard skeptics we used a bench to straighten it and were out on the water and sailing by 9am 8)

Seapup, if you get a chance talk to a mast-type-dude and ask whether a little propane torch re-annealing on the location of the bend might prove beneficial. I would think that spot would be weakened due to the bending and the subsequent straightening.
Maybe you could bring in a carpenter for the bench seat at the same time! :D

Wow, nice job repairing it. This event is one of my worst nightmares as a new sailboat owner. As I was raising the mast the first time just a couple of days ago of all things, the boat ramp at the marina that I rented a slip has power lines above it. In order to be in a position not to keep ramp occupied any longer than necessary, I had the mast in position ready to raise and then very slowly backed down the concrete ramp. The ramp had some bumps in it and as I slowly rolled over them I was keeping an eye on the mast given that most of it was hanging past the support at the helm. I was thinking to myself if that mast bends, could you even find another and how much would it be if I could find it? Which brings me to my question. If a mast gets damaged beyond repair, can they be found and how much would one cost?

Luckily, mine is ok but given how much the thing flexes, it brought concern.

Don't worry about the flexing. Aluminium is only about 1/3 as stiff as steel, so in general things made of aluminium tend to be rather flexy.

I raise and lower the mast in my slip. I don't even move it from the bow rail until I'm on the water, as I don't want it sticking way out there until necessary. The baby stays keep the mast in check when raising/lowering, and there's no part of the operation that requires access from the ground (water?). And I usually do it alone - there's no part of the operation that requires 'help', and I'm usually better off without 'help'. :D :wink:

Tom,

It was my first time to raise the mast since I purchased this boat a week ago and I agree with you, I think I'd been better off to wait til I was in the slip and just raise and or lower it there.

Thanks for the input!
