Lifting catamaran

When a catamaran needs to be lifted out of the water (for example, for maintenance on the floats), this can be done with one elevator cushion placed under the boat in the middle. The elevator cushion can then be filled with air and pressurized, lifting the catamaran out of the water and making the floats and other underwater parts accessible for inspection and maintenance.

We have several models, so depending on the type of catamaran the desired level above water the right float can be selected.
