A VSD lift is more superior to all others because it will raise and lower your boat in about one-half the time of most others. This means you can raise your boat to greater protection. The drivetrains on these lifts are very quiet with no clicking of the winch gears or pinging cables. It offers a low-maintenance gear head electric motor. With a VSD lift, it is environmentally friendly with no possibility of oil leaks. The industrial strength ball-screw is rated for 20,000 cycles at 10,000 lbs. And the best part is there is no winch cable to ever replace.
