Posts: 284 Norfolk, VA | It would help if you could elaborate on the dent and what kind of boat you are dealing with. I'm down in Virginia Beach and I may be able to get you a good used replacement mast if yours is in really bad shape (and it is a Hobie).. DanBerger@Mindspring.com

I do not think that the dent is going to be a problem because it is located in a part that is not subjected to much stress. This area is not subjected to the same kind of load as the area supported by the stays.
Since it is mainly working in flexion instead as in compression, the load is much easyer to bear for the section and the risk of collapse is much lower.
The same problem located lower on the mast would have been a much bigger problem because the wall section has a bigger roisk of collapsing when it is submitted to both a compression load and a flexion load.
Since the section was designed to support both the compression and the flexion and also a security factor and since the section affected by the dent is not subjected to the same stress, I am pretty sure that your mast is still perfectly safe.

Posts: 117 | I have a mast for my Prindle with a golf-ball sized dent about 24" from the top due to an encounter with a bridge (don't ask) ![](http://www.catsailor.com/forums/images/graemlins/frown.gif) . Anyway, I did not fix it because I found a good mast to replace it with. I still have it and was considering repairing it. What I was thinking was to shape a 2X4, or a piece of hardwood near the same size as the inside of the mast, take off the masthead, and slide it in to the dent and tap the end with a hammer, hopefully driving up the dent and not getting the wood too stuck to get out. I also have thought about using a small hydrolic ram. Northern tools sells a small wedge shaped ram and hand pump. I think it is for bodywork or something like that. If it would fit with a bar to spread the load on the good side, the dent may be able to be pushed out from the inside. Just a few thoughts. Mike | | |
