Designed to be operated when the boat is hanging in the falls at a height of 2-4 metres above the water.
Designed to be operated when the load applied to them is completely removed – that is, when the boat has been lowered and is waterborne.
Designed to be operated when the boat has been lowered and is waterborne, whether or not a load is being applied to it by the action of the ship or the sea.
That can be released at any time from any height.
