The Ron Holland-designed explorer yacht Marco Polo achieves an innovative balance of East and West.


Yin & Yang

Article Specs  
During a visit to the Cheoy Lee yard in southern China last November,
ShowBoats International was fortunate to be the first to go aboard the 45-meter (148-foot) explorer vessel Marco Polo as workers added the finishing touches before the yacht’s delivery to her owner, Roland Sturm, director and founder of Maritime Concept and Construction Hong Kong Ltd. (MCC). The stylish yacht was moored alongside a rugged Z-Tech 6000 ocean-going tug, which provided a clear indication of Cheoy Lee’s core business. Although the contrast between the green-hulled superyacht and the bright orange workboat was striking, it was also enlightening because the yard’s century-old commercial experience proved invaluable during the build process. The two vessels have more in common than you might expect at first glance because Marco Polo, unlike many modern explorer yachts, represents a true blend of motor yacht and merchant ship in both concept and construction.

"This was a pioneering project in many respects, but two points deserve particular attention," says the yacht’s designer, Ron Holland. "First, the finished product has more than fulfilled the owner’s goal of creating a European-quality yacht in China. Marco Polo is a serious market contender on the basis of build standards, as well as price and delivery [time]. Second, sea trials have proven the value of the serious design and engineering effort invested in producing a truly efficient, reliable and long-range explorer yacht."

As far as the first point is concerned, Cheoy Lee is no stranger to superyachts. In 1977 the company built the 130-foot motor sailer Shango II, then the largest GRP yacht in the world, and in 2004 it launched the Frank Mulder-designed 172-foot SeaShaw. I was impressed with the company’s facilities, which include its own metal cutting and bending shed, a propeller tuning plant, a full-size lofting shop and the latest CNC five- and eight-axis milling machines. Cheoy Lee is able to build to any class in steel, aluminum or fiberglass. Marco Polo has a steel hull and composite superstructure and fulfills both Lloyd’s certification and MCA requirements for unrestricted commercial operation. After less than two years in construction, despite some late changes to the interior design, company director Martin Lo reckons that building in China meant a cost savings to the owner of 20 percent or more.

In terms of long-range performance, Marco Polo lives up to her explorer vocation. Like her tugboat neighbor, the yacht features Caterpillar and Schottel drive units, combining the reliability and savings of commercial shipbuilding with the fascination and freedom of yachting.

"A lot of thought went into the efficiency of the propeller," says Holland, "and both single- and twin-screw arrangements have been optimized for this design."

For Marco Polo, the first hull in a planned series, a single 1,700-kW Caterpillar engine and controllable pitch propeller was adopted because it offered at least a 30 percent fuel savings over conventional twin-screw systems. The maximum speed is 14.5 knots with a remarkable 6,000-nm range at 10.5 knots. But what happens if the main engine breaks down in some far-flung corner of the globe? Enter the Schottel vectoring bow thruster, which is powered by its own Cat C7 engine and housed in a separate forward compartment. The thruster can provide a "get home" speed of five to six knots if the main is disabled by fire or flooding in the engine room.

Cheoy Lee’s experience with commercial ships has shown that the Schottel Pump-Jet, combined with a stern thruster, provides better precision maneuverability than twin-screw systems. The single, large-diameter prop, chosen for its all-around operating efficiency, is in line with current shipbuilding practices. Taking into consideration the yacht’s remote and possibly poorly charted destinations, the propeller and twin rudders are protected by a deep keel and structural skegs in case of grounding. The configuration also offers better control at slow speeds or when running downwind in storm conditions.
