The Stasher

The StasherThe Stasher is a sleeve that goes over the cruising spinnaker to give complete control over the Flasher when setting or dousing. Pulling on the control line raises the sleeve to the top of the sail, allowing it to fill and set. 

A pull in the other direction encases the Flasher in the sleeve, which permits trouble free lowering of the sail. Singlehanded ocean racers could not fly a spinnaker without a dousing sock like the Stasher because the Stasher takes the place of several long-armed crew members.
