MALTESE Maltese Falcon logo FALCON

The Maltese Falcon is not a classic yacht, she's a new class of yacht. Her revolutionary sailing system - the Falcon Rig - sets a new milestone in yachting history: 3 self-standing and rotating masts hosting 15 sails for a total sail area of 2,400 square meters (25,791 ft square), handled by the ultimate in Perini Navi Sail Control for unrivalled performance with unmatched safety and manoeuvrability characteristics.
The iconic Maltese Falcon was built for the late Tom Perkins from whom it was purchased by Pleon Ltd, for the purpose of creating a unique chartering experience.

Prölss History by Heinz Otto

A porcelain plate from the year 1958 shows the first piece of evidence that William Prölss was involved with an automated Square-sail-system. This dish was a gift from his wife to the builder of the first model of the DynaRig.

The picture below shows Mr. Prölss and a “SPIEGEL” editor standing beside the model of a 6-masts-bulk vessel. Prölss presented his concept in detail at the 1967 Shipbuilding Society Congress under the title "On the question of the economics of wind-powered merchant ships." It will be available soon on my website: , but only in german.

Peter Schenzle created "artist impressions" of the DynaRig for Wilhelm Prölss. These were shown in the film by Wiel Verlinde about the Maltese Falcon.

In his older years, Prölss, founded with partners (Frank K. Schallenberger, Captain Jens Bloch), the Dynaship Corporation in Palo Alto, Copenhagen. After the death of W. Prölss the designs were preserved by Jens Bloch in Copenhagen. These documents were only to have consequences in this new millennium as the rig wasn't built until then. Oil was too cheap and the shipowners were focused only on the situation with their competitors, so the world had to wait for it.

On many occasions and at almost all of the Hamburg shipbuilding fairs (SMM) I presented the DynaRig to shipowners, the journalists and politicians. There was little interest which would have triggered the construction of such vessels in Germany.

History First Model

At "SMM 1992" Mrs. Prölss was the special guest at my panel discussion and was presented with a small model of this ship type by the author.

History Presentation

In 2003, Prölss' development was shown at an event at HWWA relating to " SHIP + CLIMATE " . A draft by the Dutch Dykstra Naval Architects was shown to Capt. Bloch. The wait was over, a U.S. tycoon Tom Perkins had made his dream come true and was going to build the yacht Maltese Falcon .

History Small Model

As the logbook for the ship shows all the results since the launch in the summer of 2006, William Prölss has had his theoretical work confirmed in the best manner.

Now it's up to the German shipowners to drive the idea of modern (Squaresail) Rahsegelsysteme.

Prölss's original ideas in the 60's were the birth of these systems but it is in the 80's that his ideas were taken to the next level. Designs developed by Bremer Vulkan, ordered by Capt. HB Schwarz were put through a wind tunnel and developed to check new patents.

The author is on a way to install in a Hamburg museum in create space for the life work of William Prölss.

The DynaRig owes its origin to work done in the sixties by Wilhelm Prölss , at the time he believed the system could provide additional propulsion for ships. The DynaRig is effectively a square rig, the mast is freestanding and the yards are connected rigidly to the mast, in this case each mast supports six yards. The yards, unlike a conventional square rigger, have built in camber of 12%. The sails set between the yards in such a way that when deployed there are no gaps to the sail plan enabling each spar's sail plan to work as a single sail. The sails, when not deployed, furl into the mast.

The sail is trimmed to the wind direction by rotating the mast. As there is no rigging the yards have no restriction on rotation and this taken together with the curved (shaped) yards, low windage and effective single piece sail combine to give the rig improved aerodynamic efficiency compared to a traditional square rigger.

The Masts are approximately 58m in height above the bottom bearing. The DynaRig concept calls for an elongated section (to reduce the drag) and this needs to be symmetrical as the rig can be tacked to allow flow in both directions. The mast rotates about deck and heel bearings.
