Snuffers would offer a lot of windage and add more
lines and chances of fouling them in busy mark-roundings. An idea I''ve thought about (but not used myself, yet) is a belly-button retriever
line, led from the center of the sail down to the
hatch you want the sail doused into. Like on a Fireball with a
spinnaker launching chute, the halyard, sheet and guy are released and the belly-button
line is pulled smartly in. The sail collapses and is drawn into the
hatch, where it is ready to hoist again whenever it''s needed.
