The Shallow Water Boat Lift incorporates a longer polyethylene tank with a lower profile to allow for operation in a water depth of at least three feet. Constructed of durable polyethylene, the tanks have an increased wall thickness that is impact and puncture resistant. Similar in design to the UltraLift-2, the Shallow Water Lift has been engineered to keep the galvanized steel components on the top side of the tank, minimizing corrosion and maximizing the life of your lift.
