The design of this 4-deck behemoth was started in 2000. She's a beast. Just look at the beam. The boat is designed with a steel hull and aluminum superstructure.
Extensive powering studies were undertaken which included a single screw option. The final power train selected was to be twin Caterpillar 3508B A-Rated diesel engines generating 1,000 hp each for a top speed of 14.8 knots.
Here is the general arrangement plan.
Sadly, the project was stopped when the clients were tragically killed in a boating accident.
