<p>Multi-structure, sail vehicle or ice sailing vehicle whose supporting elements and rigging may adopt various configurations, capable of increasing stability, making better use of sail thrust and reducing resistance drag, and safety-steering device acting on the various manoevres. The sail angle is adjusted by varying on the structure's orientation. The linking structure is triangular and dismountable. The three articulated supports rotate at 90 degrees. The rigging may be inclined as with windsurfing boards. The rotating centre-board comprises a device for restricting the risk of capsizing and a head indicator.</p> |
