Furl (sailing)

From SpottingWorld, the Hub for the SpottingWorld network...

Furling refers to stowing or dousing a boat's sail by flaking (folding), packing (like stuffing a spinnaker into a turtle), roller furling or just lowering it onto the deck. Nowadays, it is becoming more common to use the term "furling" to refer to reefing a sail that is part of a roller furling system.
