firefox - did you drive for Direct Transit or Circle B by any chance?
I agree with your V-8 gas engine on the brain remark here in the US - dead on!!!
Agreed - Multispeed gear boxes make a difference, look at old ski boats with B&M tranny's in them
I'll add that despite what anyone thinks we have all the peices here in the US to make fast diesel production boats and the manufacturers choose not too. Why don't they, I don't know why not - maybe they just don't want to risk building a slug???
I would have thought we would have seen a Cigarette recently with diesels in it. It seems they are sending lots of boats out of the country, I'm surprised no mention of diesels?
As usaull, I'm going to challange a few things here, makes life interesting:
Please add pollution from the early diesels was a big part in killing them as well, for awhile they were banned from racing - remember?
You can't use a boat that leaves a black trail in the water for hours afterwards, see pic below - Buzzi caught crap all the time for that.
You mention Buzzi as writing the book so to speak??? - when Gancia was first built she was powered by 4 small Ivecos/Fiat and the boat was a slug!!!!
There were plenty of faster European diesel boats back then that could stomp on Buzzi. Buzzi finished, but was not necessarily the fastest!!! Remember those boats ran 2 big engines not 4 small ones like Buzzi, many a race Buzzi lost an engine and could still keep running strong. A twin engine boat with one down was dead in the water so to speak!!!
Enter Bonomi & Ferrari (not the auto maker) with Seatek and Buzzi's slug was now a star!!!
High speed diesel being a key, we in the US had them? Early Seatek's were not that high speed, they ran 3,100 rpm's, after that the natural limits of the Bosch pump stopped the engine from making power higher in the RPM range. A stock Cummins B that could rev 2,800 from the factory back then, with nothing but stronger springs and a pump tweak you could run the Cummins at 3,100 also all day - Seatek wasn't all that different rpm wise?
The surface drive (I assume Tri-max style) being a key???? I think a Merc #6 is just as fast with better steering and a greater trim range. The Tri-max set-up may weigh less than a Merc set-up BUT again take the red & yellow Shell boat with Merc #3 drives, Sabre diesels and she could outrun the Buzzi boat with ease - it just broke too often.
A boat having to be built for diesels, except for engine room length???? Look at the Buzzi hulls, narrow, very deep V, very small strakes & the only think good about them was the two steps (lots of rocker) - there is nothing else about his hulls that said a diesel should work in them??? In fact it's just the opposite, they were not made to carry the weight hence a wing to make lift and keep the boat stable because the ass was too heavy!
But you put enough Hp in anything and it can go like hell!!!
Take almost any of today's multistepped hulls and they should work great. In fact I would tell you a Fountain should probably be the best hull around for a diesel with the pad bottom, it can carry the weight easier.
What Buzzi did was put together all the right peices that could be legal for racing and win. Buzzi was very smart in seeing if you took the rules to the edge with diesels he could have enough Hp to beat the gas engine boats. Buzzi was not about diesels, he was about winning and saw that if he could squeeze in 4 diesel engines that would give him the ability to win eventually.
The one thing I think is most overlooked about Buzzi is he was a great throttleman - he pushed a boat more than anyone I have ever seen. He told me, "Joe, you need to go full throttle from the start, never slow down, make the other boats chase you - they will break, my boats won't"
