The Airdock boat lift uses four inflatable bags to lift a boat out of the water. Unlike other boat lifts, the Airdock has no permanent attachment to the seabed or to the dock, so it's permissible in marinas that do not allow boat lifts. It can lift a boat up to 34 feet long and 10,000 pounds. I've been using this Airdock for 6 years and it's in great working condition. I recently replaced the blowers on the air pump. Located at Shilshole Bay Marina. Great for multihulls and power boats. Saves thousands of dollars in haulouts and antifouling paint, which may be illegal in a few years.
Includes 4 air bags, PVC frame (approx 28' x 10', dismantles for trailering), hoses, blower, extra (new in box) size "D" bag, and patch/repair kit.
