Boat lift glossary

Displacement

The weight of water displaced by a floating boat, commonly used as a measure of the boat’s actual weight.

Why it matters

Displacement in boat lift planning

Loaded displacement is important when sizing equipment for larger cruisers and yachts.

How it connects to controller selection

A controller must work with the complete lift system. Record the lift type, tank count, valve configuration, motor setup, electrical requirements, capacity, and current controller before selecting replacement equipment. Photographs and equipment labels help Guardian verify the configuration.

What to check

Follow the lift and controller manuals, keep people clear during movement, and stop operation when equipment behaves unexpectedly. Electrical work around docks and water should be completed by qualified professionals under applicable codes.
