I'd like to build a boat lift in my garage. My wooden rafter beams are strong enough (boat is 2000#, each of two beams are engineered to hold 3500#) but there are several outstanding questions. First, how to attach a strap to the beams? Second, do I need winches on both ends of the strap (to keep movement of the strap to a minimum while I lift) or can I get away with one fixed point and another point for a single winch? Hopefully there is someone on the forum that has done this and can shed some light.
