ABSTRACT:
An improved spinnaker sail for use with kayaks, canoes, or other small watercraft is disclosed. The spinnaker is designed with a free backstay feature which eliminates moment forces on the mast. A telescoping mast is also disclosed to allow for one person set up when on the ocean. The spinnaker is also controlled by a single sheet which attaches to the lower corners of the spinnaker, forming a loop. The loop can then be held under the arms to allow the hands to be free. The spinnaker can also be reefed to 50 percent of its total area by changing the sheet configuration.
