We just lost our main halyard during a race and had to finish with a creeping down main. Made for a baggy downwind until it slipped too far! However, after trying to have a young-un scurry up the mast and determining we did too good of a wax job, we ended up rafting off of a Frers 45, climbing their mast and swinging over. Worked out well if you have someone willing to lend their big boat (and someone needing to prove their manhood). We had the crazy person doing this take the spin halyard with them and use that to swing the mast over. He then hung from the top of our mast using the Frers halyards for safety lines. Made for some good entertainment while waiting for awards.
