    Dubbed as the world's fastest diesel production yacht, the XSR48 certainly looks that and more. Seemingly to be used as a tender, this craft would propell its occupants to their destination in some form of a water-sizzling speed. They claim she has two 800 bhp engines that can zip her along at 90 mph.

    With this vessel in mind, speed is really the name of the game. The XSR48 has been compared to a super car that only thing, drives on water! Claiming if the engines are raced tuned that she will be capable of 100mph. Well..one would have to begin to think about the stability of this vessel at such high speed.

    The '70s-vintage Bertram 38 Race hulls would do just under 90 mph and some drivers experienced a condition known as 'chine-walking', a not particularly pleasant phenomenon.
    BTW, that XSR48 has a lot of ZX350 in her roofline (<<<--alphabet soup!).

    Yes TK, cool looks are one thing but it is the speed that is the issue. In fact My father and I got in a somewhat heated debate about whether thisXSR48 was faster than a Cigarette. He is a Cigarette lover..wonder if he is biased..lol.

    If it's just about speed you have a few Fountains which would do over 100mph and probably cost 1/6th of this XSR48. No idea what this XSR48 costs, but I am sure it would be around $1.5M, maybe I am mistaken. The Fountains would be around $250k-350k.

    You must be thinking of petrol engines, not diesel...?

    Sure, Fountains can't achieve these speeds except with the Mercury petrol engines.

    With petrol engines we enter a new discussion and I would rather have one of these http://www.skaterpowerboats.com/models/46rp/index.htm

    Rumours are that one that can make over 200 mph is on order...:eek:

    I wouldn't want to be sitting in one at that speed. I do it on the road, but I won't on water.

    With a Novitec Biturbo or the new Challenge Stradale you can possibly do it, but then you need the roads permitting it...;)

    I would rather fly in speeds over 200 mph...:cool:

    The XSR48 was presented as a model at the Monaco Yacht Show and I took a blurry picture of it. With this colour you will not be missed!

    I've done over 300km/h in my F430 and in my SL55 AMG. These cars are built for those speeds and I feel quite confident. Novitec F430s would do more. They can go upto 216 mph (345 km/h).
    200 mph in a powerboat is something else and would probably feel like 400 mph. I think I did 60 or 70 mph in a powerboat once and I swore never to do it again. It's mad :D.

    As AMG said, you surely wouldn't be missed. I just hope they do not paint her in that colour though. It is hideous for a boat..off course that is just my opinion.

    A couple of years ago I was thinking of building one of our smallest boats as a "crashtest" boat to run in a couple of offshore races...

    Just as a PR stunt, to be seen...maybe it is not too late :D

    Oh and as to that boat running 90mph with only 1600hp at a dry weight of 16,000lbs...show me the GPS recall and I'll believe it.

    I'm dubbing this one "G'tmo Action"

    AMG;

    Humor is one thing, but I'm out of my league on this one. So tell me, I notice lots of Dutch designs call for that downsloping windscreen at the helm. It's rather romantic in the context of high-speed, but I sure see the logic with the overhanging canopy. In this case, does this protrusion work like an automotive 'spoiler,' actually contributing to a downward force at the bow? What are the spray & wake characteristics of this hull as shown?

    On this boat the arch is part of the structural integrity and the top speed is just about 60 mph. With the original hull we were running 95 mph twenty years ago. But this boat was only 80 kg (!) plus engine, fuel and the two of us. The engine was an offshore version of the OMC 300, turning out some 375 hp they said! Scary when you think of it, but the monohull boat was the best I have ever raced with, like a laser beam...:)
