The ram vang, pushing down on the boom, saves the mast from inverting and creates space forward under the boom.
A high boom allows an easy run from wing to wing in the tacks and gibes.
A solid wing makes for easy moving around the boat.
Wings slide inboard for storage and trailering.
The self-tacking jib runs on a curved traveler spanning the deck in front of the mast.
Pulling the halyard extends the carbon fiber spinnaker pole, pulls the tack and hoists the spinnaker.
Pulling the other end releases the halyard, pulls the spinnaker into its chute and retracts the pole.
Plexus, a tough Methacrylate adhesive, bonds the spinnaker throat to deck.
