Description: Up for auction is a Hydro-dock for Boats. Protect your boat for years of convenient, care-free storage, barnacle and algae free. Easy to relocate from one location to another due to its simple bracket attachments.
How it works: Utilizes the air-water displacement principal, whereby vacuum blower motors are used to produce high volume, low pressure air as a power source. No cables, pulleys, chains or high horsepower motors are required. The lift simply uses air to lift the boat.
