Been on one of those newer 47-footers out of the Station Golden Gate in San Francisco. (Before 9/11 prohibited any civilians aboard.)
Built like a tank / submarine with super heavy riveted and welded aluminum plate, weatherproof sealed hatches, strap down seating, etc. They will self-right themselves in 3-4 seconds, if I remember correctly.
Two 420 hp turbocharged diesels. Totally redundant electronics at the flying bridge and again at the lower interior helm. The instrumentation makes the stuff you can get at West Marine look like Cracker-Jack prizes. Fly-by-wire steering and other controls. Helmsman's chair looks more like the space shuttle than the everyday cruiser. Jumps big waves and swells with ease and the mass and power to take on the big rollers.
Awesome boat, all around. Won't see anything like it at the Seattle Boat Show, so the checkbook's safe and you won't need the Admiral along to give it her blessing and work it into the budget for the next 15 years.
Curious Note: Cost millions of $$$, but still has PORTA POTTI !!! But this may have more to do with containment issues during roll-overs than cost issues. Remember the rotating, centrifugal head from the movie "2001: A Space Odyssey"?
Too bad we can't borrow one and put it on a flatbed and see just whose one ton truck with 4wd and diesel burner could pull it uphill over a 6% grade in a snowstorm. Would have great entertainment value and put all the truck guys put it on the line for real!
See you at the SBS/CBC! Joe.
