Portable, reconfigurable and resell-able. . . . LITTLE TO NO MAINTENANCE

Free-Floating boat lift designed for salt, brackish or freshwater

The Guardian Boat Lifts' TM boat lift is a hydro-pneumatic structure using advanced accelerometers to ensure a level lift. This Free-floating Level-lift can be tied to a boat dock or a standard mooring structure.
Marine-grade, UV-resistant low-density polyethylene tanks supporting a marine-grade, aluminum frame with stainless steel hardware and King Starboard® walkways
Our engineers and technicians have a complementary skill set that incorporates areas of expertise in manufacturing, engineering, quality and craftsmanship. We pride ourselves in capturing the “voice of the customers”, understanding one’s expectations, preferences and aversions.


Inboards, outboards, inboard-outboards, traditional “V” hull, pontoon, tritoon, catamaran, stepped hull, etc. Our engineers work with your boat’s manufacturer to create a support structure integrated into your Guardian Boat Lifts’ TM Free-floating Level-lift tailored to your boat hull’s needs. Dealers and staff study the conditions at the intended final location to ensure fit.


Can usually be reconfigured after initial purchase to fit larger or smaller boat as needs change. Will effortlessly moor alongside a double slip, L or U-shaped slip, floating dock, fixed dock, i.e. most any dock configuration.

No Metal Below the Waterline

When fully raised, all metal components are out of the water, minimizing corrosion and facilitating upgrades and resale of the lift. Your boat is securely dry-docked, hull and drives are safely above the water.

Automatic, Pneumatic, 120 Vac controller

Pedestal mounted controller is integral to the lift. Push of a button, puts your boat in the water for use or raises it out of the water for storage.


Raises and lowers the boat lift at no more than two degrees (2o) off level in automatic.

Rapid Launch™

Pneumatic system designed with the optimum tubing, fitting and valve openings to the time it takes to lower the boat into the water.

Remote Option

Greatly eases docking for a single person. Reduces stress on lift and dock when strong currents are present. Reduces corrosion while gone on long cruises. Water proof, fob allows for raising and lowering the lift at 100 feet or more.
