Bird Repelent
I had read in one of the sailing rags, I think it was Sail Magazine on the last page, that someone glued aluminum nails (point up) for those who arn't inovative, on the mast head. I am sure it would work on the spreaders. use very short nails; not much is needed to make an impression.I would notify anyone going up the mast about your addition before they find it the hard way.I did buy a boat that the prior owner used wire ties on the spreaders and safety rails with the point, obviously, going up. He said it worked fine, but to me, it looked like hell. I took them off as soon as I got the boat home.
