I've discovered a 4 inch crack about 1 foot from the bottom of my mast. It runs parallel to the mast and is over the junction of the sail track channel with the main body of the mast. I believe water must have sat in the mast and frozen (there is slight bulging of the mast in that area) during one of the several winters it has sat out unattended before I bought it. Wish I'd seen this before now. Haven't used Snapfish before so hope the image shows up.
Does this make the mast too unsafe to use, or can I seal up the crack (not really open) to prevent leakage, or have the crack welded? I've read many posts about the pros and cons of welding, but not sure if there's a consensus. Would trying to repair it make it weaker?
