To let any rope or line out under control. Often used as: “ease sheets” when bearing away to sail downwind
(see strobe light)
A device inserted through the hull – or sometimes permanently fitted – just ahead of the rudders or keel so that the leading edge can be inspected to see if anything that shouldn't be there such as snagged fish, weed or pieces of fishing net. Any debris that isn't too big can be swept off the keel by a flossing rope, usually a piece of rope attached to the end of a long rod that can be swept down the leading edge of the keel or rudder.
