Mechanics
Wiebel is the fastest design in the world. It has a perfect design, in that all six equations of statics have been resolved in such a way that contact between the boat and the water is minimized. Thus, the drag forces are minimized and the speed is optimized.

The vessel comprises a left forward surfboard and a right forward surfboard. A horizontal frame is provided which connects the surfboards. A central surfboard is located on the aft side of the vessel. A mast is positioned at the rear of the vessel. The mast is configured as an A-frame and held upright via cables extending from the top of the mast to the left and right side of the frame. A curved rail extends along the front end of the frame. The sail assembly comprises a curved mast, a wishbone boom and a sail, which are comparable to a windsurfsail, but larger. The lower end is connected to the rail and can slide along the rail. The sail assembly is connected to the rail via a slider and a cardan joint. A left rudder and a right rudder are provided which are comparable to a catamaran rudder. In the basic version. the vessel has two sailors. One sailor operates the sail, one sailor operates the rudder.

In front view, the gray part of the Wiebel vessel can be likened to the windsurfer on the left. The body of the windsurfer forms a counter mass which prevents the sail from overturning to the leeside. In the same way, the frame, the sailors and the leeside board form a countermass which prevents the Wiebel vessel from overturning. Due to the orientation of the sail, i.e. due to the inclined orientationto the weatherside, the windforce is directed upward. Thus, a positive wind force component is created which lifts the entire sailing vessel from the water. This minimizes contact with the water and reduces the drag force.

In side view, the Wiebel vessel resembles a windsurfer. The sail is inclined backwards in the same way as a windsurfer. The backwards inclination further contributes to the upwards direction of the wind force and thus helps in lifting the vessel from the water.

When viewed from above, the Wiebel vessel also resembles a windsurfer. The same mechanics that result in high speeds for windsurfers are achieved in the Wiebel vessel.

When viewed from side-above, the Wiebel vessel also resembles a windsurfer.
 |
When the Wiebel vessel turns, the mastfoot slides along the rail from the left side to the right side or vice versa. The sailors move in the opposite direction.

The Wiebel vessel is scalable. The basic format is a two-seater, but the size of the vessel can be increased in order to create an ocean-going vessel. The two-seater is specifically designed to break the records on the short distances. The large vessel is capable of breaking the speed records on longer distances, including the record for the Transatlantic voyage and the non-stop around the world record

The Wiebel design resolves all six equations of statics in the correct way.
The Wiebel sailboat is configured to sail as a windsurfboard. In the Powerpoint presentation which is provided below, the fundamentals of the Wiebel boat are explained in more detail.
