New arrival


This boat is the last of four Zefyr 43 Walker Wingsail trimarans designed by John Walker and built in the Royal Naval Dockyard in Davenport Plymouth.  She is a Category A Ocean going vessel and as such for compliance and CE Proofing this indicates she is able to operate in winds of up to force 10 (Beaufort scale) and to survive severe conditions. Should wind speeds exceed 30mph the wing is simply feathered in so much as a weathervane on a tall building with the result that the wing produces no resistance but is able to maintain thrust.  In turn this ensures that the wind and waves do not affect the stability of the craft.
Sisterships are trans-oceanic and one is engaged on multiple circumnavigations.
No sailcare or repairs, UV damage or reefing needed. No standing rigging ensures easy movement around the decks.

Wingsail rig

The wing area is 44 meters sq, with the main section providing thrust and the tail providing angle of attack.
The main wing and tail can be both manually and electronically controlled by the helmsman from the helm which is not exposed to the elements. For first time use approximately 30 minutes training is required for a novice and no complicated tuition is required enabling complete control.

The yacht is simply steered like a car turning the wheel steering to port or starboard and the yacht will respond accordingly, no booms sails or rigging to worry about.  All that is required is a slight shifting of the tail and flap to take account of the new direction.  This is done by merely engaging a few knobs as you would for flicking a few switches on your car dashboard whilst driving.
