mainsail stuck up
Yesterday was first sail on 1965 Columbia 26 Bill Tripp design. I hoisted the mailsail 90 percent up and then halyard locks up. Tried to go aloft on jib halyard and it locked up. I am going to buy two ascenders to fix. Can anyone tell me what to look for if I suspect the blocks at the top of the mast. This is an external riged classic sailboat.
