    That supersized speed boat needs some shade areas.

    As it is, the canopy side glass is going to roast some skin like a magnifying glass.

    Is there a second bridge or control area for rough weather should the forecast change on the way back from a day jaunt?

    Looks like a fair weather tender for a real yacht.

    It's sexy looking though, just not that practical.

    Anyone want to explain how that anchor works when you're swinging on a 10:1 rode at high tide? It appears to drop out the bottom, how does it not chafe?

    Nothing but an over priced billionaires toy.

    Maybe the bow roller is on a firm sledge and so lowered to below the bottom when the anchor drops, only the centerline cut shows a bit of the anchor set up, the bottom pictures don't even show a anchor hatch . . . :eek:

    They don't tell the price, they'll only send the bill, maybe it's upfront paying nowadays . . :eek:

    Not I can afford to buy one or dream about owning one.. But it's just so interesting & got me all started with imaginations. I've always been fascinated by the Bugatti WR16, but also thought it doesn't quite seem to make sense to drive rubbers (/tires) with it. You can't just change the tires, you have to change the wheel! The entire wheel with the rim! That's probably a bit much by today's environment mindsets.

    No doubt the car is absolutely a masterpiece, but I'd say it should make much more sense to use the WR16 to drive propellers instead, like the Niniette 66.

    But the Niniette actually doesn't have the WR16, it's got two MAN V8 instead.. I can see why the marine V8 chosen, it's a boat after all. But that's also like the heart & soul taken out something branded a Bugatti. How much Bugatti can it be without the WR16? 30%??

    And that was where it all got started with me thinking how the WR16 can fit to the boat. This is pure shot in the dark, and probably totally nuts. But I'll certainly appreciate anyone willing to share more insights, or where it can go wrong. I'd love to learn more.

    This is how I'd (imagine) do it.

    I'll use the entire 4WD drivetrain with the WR16. The FDR at the wheel hubs will be about 2:1 at the 7th. Next I'll add a 0.71 reduction from there for driving each prop shaft (assuming prop driver 1:1). This will make the 5th as the gear with 2:1 FDR instead, so it'll be able to drive the full range 1000~3000rpm prop @ 2000~6000rpm engine. The 6th & 7th can still be used to cruise 1500~2000rpm prop range between 2000~3000rpm engine, so this can save fuel.

    The 4WD with all the original sophisticated top-rate differentials will enable a very good precision thrust vectoring with the 4 propellers! So this is conceptually the real Bugatti on water!

    The front and rear power split seem a bit different, so I'd fit maybe 16.75" props (positioned L/R stern near center line) driven by the 2 rear wheels; and one size smaller prop, maybe 16.5", further from L/R stern center line, and maybe a bit more forward & higher, driven from the front wheel hubs.

    Sound crazy?

    BTW, crunching some numbers with some online formulas and calculators, seems the 1000 or 1500 hp WR16 is more than powerful enough to push 10tons/20m to 48 knots.

    Also not to forget even the brakes can be kept! (making sure props fully stopped before reverse..!)

    Agree, but it would be nice at anchor, without wind, without fuel on board, without flammable items nearby, without alcohol.

    You get the picture. What could possibly go wrong? :rolleyes:

    Still might be good place to put the cooking stove or barbecue plate tho. It's 20m boat gotta have loads of stuff to balance the hull.

    40+knot planing hull with wave-piercing bow, and open cockpit (full of fancy people)?

    ain't reason speedboats have the types of bows they do is so when they hit an unexpected wave the boat defects up but the wave doesn't come crashing into the superstructure and people? And if you porpoise after smacking a small rogue the big speed boat bow will handle it for you. I'm thinking this thing porpoising at speed after hitting a wave could be a problem and it could nose-in for very sudden stop without seatbelts or airbags.

    I've had large boat wake waves sneak up on me across vast distance in other wise nice calm water.

    IIRC a water-ballon will take out a car's windshield at 40mph.

    I think it's just plain ugly.
