Abstract
Dampers for mounting on a dock to control landing a boat. The dampers may be used individually or in damper systems made up of a plurality of dampers. Each damper has a flexible body with one or more sidewalls defining an inner chambers, and orifices are provided in one of the sidewalls to allow the chamber to be filled with water when the damper is in an at-rest state. When the boat approaches the dock and contacts the damper or the outer set of dampers in a damper assembly/system, the collision or impact force applied by the boat against the outer surfaces of the damper(s) causes the damper body to be compressed, which causes the sidewalls of the chamber to collapse so as to expel water out of the inner chamber via the orifices so as to reduce the speed of the boat at a desired rate of deceleration.
