We stepped and un-stepped our mast, 50ft above waterline and double spreaders, every year for about 5 yrs then we fabicated a "yard trailer", we never had any problems, id the wiring, we used quick conects in such a way that the black wire had to go to the correspoding black wire then reversed the connectors for the other black wire. Slow and easy is the secret. Good luck
Bring a friend along.
