Abstract
A spinnaker pole for controlling a spinnaker on a catamaran or other sailcraft has a cap on its fore end and a guy is reeved through a bore that extends axially through the cap and the fore end of said spinnaker pole to exit the pole through an opening in its central portion for belaying in a cam cleat fixed to the pole aft of such opening. A first line extends from the front surface of the cap for attachment to the front of the catamaran's port hull and a second line also extends from the front surface of the cap for attachment to the front of the starboard hull. The aft end of the spinnaker pole is attached to the catamaran's dolphin striker. The first and second lines serve to stabilize the pole's fore end and also prevent the spinnaker sheets from becoming entangled with the pole's fore end when the spinnaker is jibed.
