An explanation of names: Viking Yachts, Princess Yachts and Viking Sport Cruisers (VSC)

In 1995 Viking Yachts, legendary for building sport fishing boats, saw increasing U.S. demand for a sporty European motor yacht. Viking partnered with the high-end U.K. builder, Princess Yachts, to bring their boats into the U.S. under the Viking brand. It was named the Viking Sport Cruiser (VSC). Thus in 1996 the first Viking Sport Cruiser was imported into the U.S. By the later 1990’s this collaboration expanded to 13 models from 40′ to 84′. Beginning in model year 2011 Viking and Princess changed the Viking Sport Cruiser name back to Princess Yachts for all boats imported into the Western Hemisphere. As of 2017 Viking Sport Cruisers continues as the distributor under the Viking Yachts umbrella to import Princess Yachts.

Viking Motor Yachts share a unique lineage with legendary blue-water Viking Convertibles that are built for ocean fishing far offshore (List price of a similarly-sized 2018 Viking Convertible is $2,700,000). Therefore Viking Motor Yachts are built to higher construction standards and for better performance underway. This becomes particularly important to recreational boaters when sea conditions change for the worse. A lesser boat with a huge-volume interior and all the bells and whistles is more likely to take a beating. You will feel it too.

There are many benefits to owning a motor yacht intended for family cruising rather than a convertible intended for offshore fishing. These benefits include more comfortable living accommodations and half the fuel consumption per nautical mile. In conclusion, a motor yacht with “convertible DNA” offers the best of all worlds for recreational boating.

Length:  50 feet
Beam:  14 feet 5 inches
Maximum Draft:  3 ft 8 in
Deadrise at Transom:  19 degrees*
Dry Weight:  33,600 lbs (approx 40,000 lbs with fuel & water)
Gross Tonnage: 26.44
Fuel:  500 gallons diesel
Engines:  Twin turbocharged Volvo Penta 675 hp D-12’s with 1100 hours. (This is an upgrade from standard 450 hp engines. The larger engines make the boat 6 knots faster.).
Thrusters:  Side-Power SE95 24V in bow (new replacement in 2015) and Side-Power SE100 24V in stern (new addition in 2018) with twin joy stick controls. 
Transmissions:  Twin ZF 311A transmissions with a 1.501 ratio.
Generator:  Onan 11.5 Kw (upgraded replacement in 2015 from original Onan 9.5 Kw unit)
Cruising Speed:  28 knots (32 mph)
Maximum Speed:  30 knots (35 mph)
Accommodations:  Sleeps 6 people.  2 staterooms with Queen beds & 2 full heads. In addition the opposing sofas in the salon can be combined to form a King bed.

*Deadrise at Transom describes if the underwater part of a boat is shaped more like a sharp- or dull-knife. A sharp knife can cut through waves at higher speed with less pounding. However a dull knife will pound through a wave at higher speed. Pounding through waves is more likely to hurt your back, neck or knees. This is why a boat with a large interior volume and greater beam may be a bad choice if you plan to use your boat anywhere other than on a quiet lake. A Cigarette boat will typically have 24 degrees of deadrise at the transom. An express cruiser will typically have 17-20 degrees of deadrise at the transom. A flybridge motor yacht (typically with a large interior volume) will typically have 13-16 degrees of deadrise at the transom. A bulky heavy boat may have a deadrise below 10 degrees but it may not pound at all because it is built for slow speed. JAWS II is a flybridge motor yacht built upon an express cruiser hull. It is built for high speed performance.

ABOVE: 1) The Flybridge Deck comprises the area above the salon, galley and cockpit. There is a companion seat next to the driver, U-shaped seating around a large table and lounge pads aft where two or three people can sunbathe. The flybridge can comfortably accommodate a dozen people. 2) The Lower Deck includes two staterooms with Queen beds and two heads on either side of the hallway. The engine room is shown to the left of the middle stateroom. Not shown: The lazarette is below the cockpit seating. It is a generous storage area that instead could have been built to include a small bed and bathroom for a captain. 3) The Main Deck includes the salon with two opposing sofas that mate to form a King bed. The galley is to the right of the small sofa. The cockpit seating is shown on the left.
The flybridge comprises the area above the salon, galley and cockpit seating in the rear. It can comfortably accommodate a dozen people.

Many consider the 50 Viking Princess Yacht to offer an ideal balance between boat-like performance and flybridge motor yacht luxury*. This balance includes:

Length to Beam ratio* (excluding pulpit):  3.5
Horsepower to Dry Weight ratio:  0.04
Hull:  solid fiberglass non-cored hull (not balsa-cored)
Center of Gravity (COG)**:  moderate height above the waterline, moderate freeboard and a lightweight Bimini top
Windage**:  moderate freeboard and an open flybridge without a plastic window enclosure
Performance***:  seaworthy and fast Bernard Olesinski hull with excellent fuel economy

* Most boats have a length to beam ratio of 3.0. A slender boat with a ratio of 3.5 gives up interior volume to offer a gentler ride in bigger waves. For example a Cigarette-class boat will have a length to beam ratio of 4, 5 or even higher. Do you want a floating condo or a performance boat?

** Many new boats are built higher to accommodate a third full beam stateroom under the raised salon. This raises the Center of Gravity (COG) and causes greater Windage  A boat with a higher COG can rock more when traveling or at a dock. It will also be more likely to tip over in rough weather. A boat with greater windage will be blown more by the wind. This can decrease fuel economy and make docking difficult on a windy day.

Straight shaft propulsion vs pod drive propulsion
Straight shaft propulsion offers simpler & less costly long-term maintenance than pod drives like IPS or Zeus. In addition the repair costs for striking an underwater object are much higher for pod drives because much of the motor is exposed below the hull. For most boaters the high cost of pod drive maintenance is much greater than the fuel cost savings pod drives offer. Ask your mechanic.

Princess Yachts Viking Sport Cruiser lower helm visibility
The lower helm on JAWS II offers uncommonly excellent visibility.

Compare the visibility of this other boat brand to the lower helm visibility of JAWS II. The roof blocks forward and side views. Imagine driving at night or in rain. It is not uncommon for these boats to be driven while standing on the helm seat and steering with one’s feet. This boat owner has had to do just that driving friend’s boats.

* Replaced both Electronic Control Units that are the brains of the engines. The ECUs collect and process signals from various on-board sensors.
