Can a barge-mounted crane lift its full rated capacity over the water?

Barge-mounted cranes experience significant capacity reductions when operating over water due to the vessel's response to off-center loading. When lifting loads over the side or at extended radii, the barge will list (tilt sideways) and trim (tilt bow-to-stern), which shifts the crane's center of gravity and reduces its effective lifting capacity. Most barge crane operations are limited to 75-85% of the crane's land-based rated capacity.
