4.6 - Dousing Sock (The UK Stasher)
The simplicity of the UK Sailmakers cruising spinnaker is further enhanced by the addition of the UK Stasher. The UK Stasher is a sleeve that gives you complete control over the cruising spinnaker when setting or dousing the sail. The unique design of UK's Stasher offers advantages over all other manufactured dousing socks (see drawing for construction details).
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 cruising spinnaker 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.
