Abstract
Abstract A pocket sewn into a spinnaker sail with the purpose in mind of creating a self contained receptacle from which the spinnaker may be launched. The pocket once sewn on is used for a place to store the spinnaker as an added benefit. The primary purpose of the pocket is to have a device from which to launch the sail which does not require devices separate from the sail itself and which eleminates the problems associated with launching this particularly cumbersome sail. The spinnaker is raised while contained in the pocket and while being raised is pulled from the pocket by the use of the lines attached to the feet of the sail.
