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.

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.

Both shafts and propellers were removed and rebalanced.
