WHAT IS A 4-POST BOAT LIFT?

The Industry Standard for Piling-Mounted Boat Lifts

A 4-Post boat lift raises a vessel vertically between four pilings using a cradle and cable system powered by a drive motor.

This configuration is widely used for residential docks, canal homes, and marina slips because it provides stable lifting performance and straightforward operation.

4-Post lifts are ideal when your dock includes pilings surrounding the boat slip, allowing the vessel to be lifted straight up out of the water.

Common applications include:

  • Waterfront homes along Florida canals

  • Intracoastal waterway properties

  • Private marina slips

  • Open-water dock installations
