The Maltese Falcon sailboat is a clipper sailing luxury yacht owned by American Tom Perkins, and is the largest privately-owned sailing yacht in the world at 289 feet (88 metres).

The Maltese Falcon was built after the Dynaship or Dyna-Rigg concept, a 1960 invention of the German engineer Wilhelm Prölss which was intended to operate commercial freight sailing ships with as few crew as possible. The ship has fifteen square sails (five per mast), stored inside the mast; they can fully unfurl into tracks along the yards in six minutes. The three carbon fiber masts, which are free-standing and able to rotate, were manufactured and assembled by a company financed by Perkins at the Perini Navi Istanbul Yildiz Gemi (star ship) yard in Tuzla, 50 miles south of Istanbul, Turkey, under the supervision of the English company Insensys and Dutch company Gerard Dijkstra & Partners. Other design was provided by Ken Freivokh Design. The Falcon was the third yacht built by Perini for Perkins.

The Maltese Falcon yacht is easily controlled and has been seen to sail off her anchor and away from berths within harbors. The yacht’s sophisticated computer detects parameters such as wind speed automatically and displays key data, however Kristenson does not permit the computer to actually sail the yacht. An operator must always activate the controls, yet it is possible for a single person to pilot the mega-yacht.

The Maltese Falcon has two 1800 horse-power Deutz engines running at 1800 rpm with a top speed of 20 knots with minimal wave-making and virtually no vibration or noise and with a smooth and non-turbulent wake.

The sailboat has a permanent crew of 18 to maintain the technical aspects including the rig and to operate the onboard “hotel”, which can accommodate twelve guests plus four guest staff. The boat also includes an onboard gourmet chef and stewards and stewardesses.

Maltese Falcon Dyna-Rigg Sailing System

Insensys Team, including Damon Roberts designed and manufactured the Maltese Falcon Dyna-Riggs in the Tuzla ship yard, Turkey. The design, testing and manufacturing of the rigs was completed over a three year period. All aspects of the rigs were incorporated and tested to ensure that the design and Finite element analysis matched the actual loads whilst sailing.

The DYNARIG owes its origin to work done in the sixties by Mr W. Prolls, 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.

Insensys have also incorporated their fiber optical strain monitoring system that monitors the loads on the rigs to ensure that the carbon structures are never overloaded whilst the yacht is sailing. The Fiber Bragg grating system was embedded within the rigs during manufacturing process of the carbon structure. The system monitors the strains in real time and transmits the loads to the bridge such that they are understood whilst sailing.

    Sounds like 22nd century already. What is the speed up wind and what does it have for engine power?
    Thank you
