Wilhelm Prölss intended to operate cargo ships with a fuel-saving philosophy and as few crew as possible, met with Perkins' approval, and the project was signed into build in Tuzla. The three self-standing rotating carbonfiber masts were not a Perini Navi deliverable; they were manufactured and fitted to the yacht at the Perini Navi premises in Tuzla under the direct responsibility of Perkins and the supervision of Insensys, Ltd, a British carbonfiber specialist. Ken Freivokh designed the vessel's interior decoration, and Perini Navi fitted her out.
The 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. An operator must always activate the controls, yet it is possible for a single person to operate the yacht. In a radio interview for the

Damon Roberts of Insensys, Ltd. was responsible for designing and manufacturing the DynaRig of ''Maltese Falcon'' at the Perini Navi premises in Tuzla, Istanbul. The design, testing and manufacturing of the system was completed over a three-year period. Exhaustive
were carried out to ensure that the complete assembly would sustain the loads under sail.
The DynaRig owes its origin to Wilhelm Prölss' research in the 1960s. The DynaRig consists of freestanding rotating masts with rigid
. Each of ''Maltese Falcon''s masts supports six yards, which, unlike a conventional square rigger, have built-in camber of 12%. The fifteen square sails are set between the yards in such a way that when deployed there are no gaps in the sail plan of each mast, enabling them to act as a single airfoil. The furling sails are stored in the mast and can be deployed along tracks on the yards in 6 minutes. The sails are trimmed by rotating the masts. As there is no rigging, the masts and yards can be rotated without restriction for all points of sail, making ''Maltese Falcon'' a capable upwind clipper.
The length of the masts measures approximately above the bottom bearing. As the rig can be tacked to allow flow in both directions, the mast rotates about deck and keel bearings and have symmetrical elliptical sections for better aerodynamics in both flows.
Insensys also incorporated a
al strain monitoring system into the spars to analyse real time loads under sail. A
system was embedded during wet layup of the carbonfiber structure. The loads are transmitted to the bridge monitors.
''Maltese Falcon'' has received industry prizes from shipowners and the press. It has also won the Perini Navi Cup regattas on two occasions as well as the Palma Superyacht Cup in 2010.
