Re: repairing dent on the mast

Aluminum doesn't like to be bent and bent back. It fatigue cracks very easily. That method will make it look nicer, but isn't going to return it to it's original strength and may make it weaker than it currently is.

The plate that bridges this sounds like a better solution to me. Talk to another rigger and see if you get the same advice.

Re: repairing dent on the mast

Find out who the mast manufacturer is and get their opinion. What brand of boat is it? Do you know what brand of mast it is?

Alex_W is correct aluminum does not like to be worked and can/will fatigue easily. If that mast breaks and comes down you will be spending money on a lot more that just a mast; all rigging (running and standing), sails, roller furling, fiberglass repairs, hospital bills, higher insurance premiums, etc.

You do not want to wind up with this:

Re: repairing dent on the mast

mmazour: What is the story on that spreader seperation? The photo is overexposed, but it looks like that could be an Isomat mast, which is what my Pearson has.

Re: repairing dent on the mast

Alex_W: Yes it is an Isomat mast. Not sure what happened. Went sailing on a high wind day 18-20 with 30 gusts. Coming back into the marina and one of the crew points up and goes "is that supposed to be bent back like that?"

The manufacturer and surveyor say it may have been a defect in the weld that just finally failed 19 years later.
