Hey All,

I have a Hobie 16 that had the mast bent which created a horizontal crack just above the tang during transportation. The crack is significant and the mast was not seaworthy at all. A quick solution was created by riveting two rectangular aluminum sheets on either side of the mast as braces. This seems to have worked well, as I've sailed the boat 5 times since the repair. It even capsized once and held together while being righted (I even over righted it and recapsized it, causing the mast ball to hit the water pretty hard, still held). I know that I should try to seal the crack to avoid water filling the mast while capsized, but my question is if anyone else has tried to make a more permanent repair to a type of crack like this?

My thoughts were that maybe someone can just straight up weld the crack, but I was also thinking it may be neat to see if anyone has tried to make a two-part mast before? Maybe I should just leave it. Thoughts?

Others have more knowledge than I.
The aluminum tubing (mast, cross bars etc) is anodized to make it harder and more durable.
If you weld the mast, the heat of the weld will weaken the mast.

I suggest you shop for a used mast and replace it ASAP.
While the mast will not fall down, you might suffer a break and thus lose the mainsail....
While the 'two plate' repair might work well, there can be some pretty strong stressors at work.

good luck

There are plenty of extra Hobie 16 mast out there. If anyone needs one, I have two extras hanging from my fence.... :D

^^^^ agreed, get a replacement mast and/or a parts boat for cheap that has a good mast. There's a bunch out there and a good chance if you go to a few regattas someone can bring you a mast.
If your rigged one breaks it could tear your sails up or leave you stranded good.

If the mast is cracked above the tang, you could simply cut off thr top of the mast and install a comptip (fiberglass mast tip).

Otherwise, do as others have suggested and find a replacement used mast. There’s no reason to mess around with a bandaid fix on your mast. It’s going to come back and bite you in the rear at some point by either breaking, filling up with water during a capsize, or causing some other headach that just isn’t worth it.
