Construction of the Air-Dock Boat Lift

Air-Dock boat lifts are constructed of a very tough Elvaloy, PVC, and Urethane blend. This material is used primarily for industrial applications such as membrane roofs, pond liners, oil spill booms, truck tarps, and some inflatable boats. This material is known to last over 30 years on membrane roofs exposed to UV light. The material is patchable and all Air-Docks come with a patch kit.

For Personal Watercraft, Jet Skis & Waverunners

Personal Watercraft (PWCs),
Jet Skis & Waverunners

Two Main Air Chambers
Our personal watercraft (PWC) boat lift models have two main air chambers connected with nylon ropes through stainless steel grommets. The overall width of the PWC model boat lift can be adjusted to match the width of the jetski by adjusting the length of this rope. Each main air chamber has an internal guide chamber which is inflated once during installation. These remain inflated to keep the outside edges of the PWC boat lift floating and to guide and center the PWC as it slides in.

We offer two sizes of personal watercraft (PWC) boat lifts: one for 2 seat PWCs and one for 3 seat PWCs.

 

For Small Boats

Small Boats

Two Main Air Chambers
Our small boat lifts have two main air chambers connected with acetal plastic rods through hinge type “knuckles” (like a piano hinge). Each main air chamber has an internal guide chamber which is inflated once during installation. These remain inflated to keep the outside edges of the boat lift floating and to guide and center of the boat as it slides in. These internal guide chambers can be size adjusted to match the width of the boat.

We offer 2 models of small boat lifts. The two main air chambers of a common A-Model lift, for example, weigh approximately 86 pounds together.

 

For Medium Boats

Medium Boats

Three Main Air Chambers
Our medium size boat lifts have three main air chambers. The two stern chambers are connected with acetal plastic rods through hinge type “knuckles” (like a piano hinge). The front chamber is connected with a shock cord through grommets (like a shoelace). Each stern main chamber has an internal guide chamber. Bow main chambers have two. These internal guide chambers are inflated once during installation and remain inflated to keep the outside edges of the boat lift floating and to center and stop the boat as it slides in. These internal chambers can be size adjusted to match the width of the boat.

We offer 14 models of medium size boat lifts. The three main air chambers of a common C/B-Model lift, for example, weigh approximately 118 pounds together.

 

For Large Boats

Large Boats

Four Main Air Chambers
Our large size boat lifts have four main air chambers. The port and starboard chambers are connected with acetal plastic rods through hinge type “knuckles” (like a piano hinge). The front pair is connected to the stern pair with a shock cord through grommets (like a shoelace). Each main air chamber has an internal guide chamber. These internal chambers are inflated once during installation and remain inflated to keep the outside edges of the boat lift floating and to center the boat as it slides in. These internal guide chambers can be size adjusted to match the width of the boat.

We offer 10 models of large size boat lifts. The four main air chambers of a D-W/D-W-Model lift, for example, weigh approximately 300 pounds together.

 

For Catamarans, Pontoons and Tritoon Boats

Catamaran, Pontoon and Tritoon Boats

Four Main Air Chambers
Our Catamaran, pontoon, and trimaran boats lift models have three main air chambers. The stern chambers, which are usually separated by “spreaders”, are connected with plastic rods through hinge type “knuckles” (like a piano hinge). The front chamber is connected with a shock cord through grommets (like a shoelace). Each stern main chamber has an internal guide chamber. Bow main chambers have two. These internal guide chambers are inflated once during installation and remain inflated to keep the outside edges of the boat lift floating and to center the boat as it slides in. These internal chambers can be size adjusted to match the width of the boat.

We offer 7 sizes of catamaran, pontoon, and tritoon lifts. The three main air chambers and spreaders of a typical C24/CAT11x9 boat lift weigh approximately 180 pounds.

 

Other Inflatables

Air-Dock's inflatable air chambers are constructed with techniques developed over fifty years on military boats and life saving devises.

Military proven field applications have provided invaluable data from products designed and used under the most adverse conditions. The Air-Dock boat lift requires much less pressure, however, than inflatable boats and is used under less stressful conditions. By comparison, the Air-Dock boat lift requires approximately 1/2 pounds per square inch while a typical inflatable boat requires 2 to 4 pounds per square inch.

Inflatable air chambers inherently have tremendous lifting power. Air-chambers like these are also used to lift commercial airliners for maintenance and repair.

Material
Air-Dock's inflatable air chambers utilize the latest materials and construction techniques. They are constructed from a Coast Guard approved Elvaloy® coated/polyester reinforced fabric. This fabric is chosen for it's high tear strength and puncture and abrasion resistance. All air-retaining seams are constructed with advanced high-frequency sealing techniques. Each one meticulously assembled, inspected and tested to meet or surpass military standards, including MIL-I-45208A.

The Air-Dock material has a polyester fabric base which gives it a tensile strength of 400 pounds per lineal inch. This strength makes it highly resistant to punctures and tears.

When it comes to inflatable boats, most are constructed of vinyl (PVC) or Hypolon®. Vinyl boats are much less expensive but do not hold up well to sunlight. Hypolon® boats have been known to last twenty years or more with exposure to sunlight. The Elvaloy® material has been tested in an accelerated weather chamber and has shown to be even more resistant to sunlight than Hypolon®. It has also been proven to be more abrasion resistant than vinyl or Hypolon®.

Elvaloy has been used for many years as membrane roofs on buildings, chemical tank covers, pond liners, oil spill containment booms, and more recently inflatable boats.
