Spin pole lifts
My old First 32 (1983) had these as well. If you look at the original Beneteau brochures, and from what i understand, they used to use two spinnaker poles in Europe. Instead of dip-poling, or end-for-end gybing, they'd raise one and lower the other. There was even two spin pole mast cars on some of the old boats too. My boat had an Isomat mast and was a French-made boat. By the way, those exit sheaves never really worked great anyway. Anytime the pole was brought aft, it created an un-fair lead for the lift line and it would bind up.What year is your boat?Tim
