This new cat (Called the SPX for "Sea Based X-Band Radar") currently on the way to North
Korea seems to have a lot of advantages as a potential cruising cat:
Plenty of bridge
deck clearance to avoid wave slap
Excellent stability - especially with ballast
tanks flooded to increase
draft from 10M to 30M. No rolling at
anchor - even in mid ocean.
Engine noise a long, long way from accommodations
Combination
dinghy davit and helipad
Good bracing between hulls
Fits on Dockwise transports
Dual hybrid drive provides cruising speed of 8 knots from 12 megawatt genset.
Charter layout sleeps 85
Excellent
radar - can track a baseball in
San Francisco from the Chesapeake (I'm not making this up!) so
tracking missiles over Pyongyang should be easy.
