Athwartship S Bend in Mast

[benz]

My 27' Irwin's mast had an S-bend also when I bought it (some chump overtightened the rigging, and it went so far as to crack the mast support beam in the cabin, so I had to replace that before ever I could sail her). The bend was slight enough that the slides still ran smoothly in the track (very important), and we put about 3000 miles of often-rough blue water under her keel with no problems from the mast. Remember that it is better to go to sea in a boat you can afford than to stay on land wishing for a boat you can't.....
Of course, I'm not a rigger, so if one of them weighs in with an opinion, it's likely more valid than mine.
