4.5 - Cruising Spinnakers
The Cruising Spinnaker is an asymmetrical pole-less spinnaker that combines the ease of handling of a jib or genoa with the pulling power of a spinnaker. Because the generic name is so long, and because it improves a boat's light-air downwind speed so much, we named the sail The UK Cruising Spinnaker.
The Cruising Spinnaker looks and performs like a spinnaker, but it requires none of the expensive extra gear needed for a spinnaker — no pole, no track on the mast, no pole lift, no foreguy and no afterguys.
In short, with the addition of a spinnaker halyard, a Cruising Spinnaker can be set and used on any boat equipped to set a jib. UK's Cruising Spinnaker is made of lightweight nylon spinnaker cloth that comes in many different colors which you can use to create your own color scheme.
