Crane Service on St Thomas

Can anyone recommend a crane service or a truck with a boom to lift a 700 pound marine generator into a 50 ft sailing catamaran. Reach would be around 20 - 25 ft.

Also an area to park the boat for the lift...?

Thanks....

Give Gene a call. They have the crane and the experience.
