Here's a preliminary design for a 141' trideck motoryacht. The yacht was to built with a steel hull and aluminum superstructure. Power was to be supplied by twin Caterpillar 3508B engines rated at 825hp each for a top speed of 14 knots. Range was to be 6,000 nautical miles.
Here are the plans.
A couple of points about the arrangement. Please note the owner's stateroom/suite located on the main deck forward and his private office which opens to the sea.
The actual stateroom is up a half-a-flight of stairs to bring the space up over the raised foredeck for unobstructed views through 180°.
Also note the tender garages that are accessed through the hull side, both port and starboard. This was necessitated by the lower lounge forward of the swim platform which contains some nice loose furniture, wet bar and day head.
Displacement 848,771 lbs (half load)
