TWR Dock and Marine

BOAT LIFTS

Quiet, durable lift systems that make launching your boat effortless. Poly Lift, Roto Lift, Hewitt and Wave Armor.

EFFORTLESS
LAUNCHING.

A good lift protects your boat from water, weather, and wear. We install four proven systems, pick the one that fits your boat size, your water depth, and how you use your waterfront.

A lift cycle, start to finish.

  1. 01

    Boat arrives

    Drive the boat into the slip like any normal dock. The lift waits underwater, out of sight until you need it.

  2. 02

    Settle over the cradle

    Position the boat above the lift tanks. On a Poly Lift, this is effortless because the HDPE tanks are wide and forgiving.

  3. 03

    Air fills the tanks

    Press the button. An air compressor displaces water from the sealed tanks through a one-way valve. The lift begins to rise.

  4. 04

    Boat clears the water

    In about a minute, the boat is fully above the waterline. No scraping, no electricity in the water, no moving parts underwater to corrode.
