I have been sailing and racing a mast that was way bent from (just guessing) hitting a bridge. No inside kinks like yours but I straightened with chains and hydraulic jack. Built a outside sleeve out of PVC to spread the fulcrum pressures of the jack. It's not perfect and may be more bendy to aft if I get on the backstay tensioner a little. Just went through the same process with straightening a 26X boom and used a smaller jack and 1/4" Amsteel instead of chain, it came out perfect. Placed a short length of AL pipe inside the boom (2') to spread the bending load caused by my cabin top traveler (26X). Anyway I'm too cheap to buy a new mast and boom.
Could you place a 3" x 2' AL pipe into the mast at the spreader point and hold it there by drilling through it with the spreader attachent hardware?
