    on sunday ken warby rang in on abc radio to announce that he and his son have almost finished a new boat and are fitting the jet engine this week . his son is going to pilot it and try to beat his dads best of 511 kmh. i thought this might be of interest to the speed freaks out there.

    i always wonder if jet powered boats like warbys and campbells truly qualify as boats. to me they are more like hybrid aircraft. should a boat attempting a water speed obtain its thrust in the water by propellor ?. if you put a long skeg under a jet fighter and fly it with the skeg touching the water you could claim a water speed attempt. i think this topic has been mentioned before but i would like to know what others think.

    I think it's still a boat, floats, starts & finishes in the water, rudder is in the water. hope all goes well for them.

    Usually it doesn't go so well.
    Statistically they have an 85% chance of pilot getting killed during the attempt: http://en.wikipedia.org/wiki/Water_speed_record.

    But, in spite of this bitter cynicism of mine, I truly hope Warby's son will make it.

    i see your point jeff but you could say that about an amphib aircraft as well. are there seperate records for water and jet propulsion. daq , ken warby mentioned the 85 percent mortality rate to. he knew a lot of the people who died . he does have a successful track record though and sounds pretty confident. the second time he broke his own record was by 29 mph which is a huge advance for a second attempt.

    "Ken bought a couple of Rolls Royce jet engines from Italy, some timber, and they were away. "

    Blokes like Warby are an inspiration. Hands on entrepreneurs. Might mention another recent hero who died the other day - the only guy ever to build his own car to win a Grand Prix, Jack Brabham.

    Warby ( the elder ) had some boffin in his camp who was a key man in the successful designs, if he is no longer involved ( wasn't a young man then, probably gone to eternity by now) I would not be so confident it will turn out the same way.

    Jack Brabham was a humorous man, he said he wanted to die without an enemy in the world, by outliving the ******** !

    What is it about the Aussies? They are either crazy or they have bigger balls than anyone else. Is it something in the water? I admire their courage and abandon greatly, but maybe not their absence of aversion to danger.

    Sir Jack Brabham was a legitimate hero. May he RIP along with Fangio, Nuvolari and the rest.

    I dont think we can say that they are crazy - in the case of Brabham, he was an experienced mechanic, and Warby had the help of some clever academics for the design.

    I note that neither of them have died from risky behaviour, unlike a few less forrtunate people.

    For determined men, you might like to get a copy of the film "worlds fastest Indian", New Zealander Burt Munro's world motorcycle speed record for an interesting story.

    That is a valid argument but it also comes into play on land speed records. At least on land, there seems to be more recognition of classes on whether the car is being driven by power to the wheels or by a jet with no connection to the ground. I don't place jet water speed records in the same category with propeller or any other water reaction driven record. Still, Ken Warby is a true hero in the waterspeed field.

    I also suspect that it would be no small task to build a prop driven float aircraft that could beat this record.
