Interesting to look at the records over the past few years. Chip Romer has added 40 mph to the NC4P2 record (Cat 36 - 42'). 152 mph was the record before he showed up. More power in a better hull.

C4 cats with F2 engines (525EFI) remain in the 116-120 mph range since that engine hasn't changed and nobody puts 525s in 388 Skaters.

One thing I can't figure out is the PC4S2 record of 140 in 2009 by Dennis Hillhouse. S engines are defined as factory stock (less than 500 HP). Does anyone know the details on that boat?

Excellent thread guys.

Pro Cat 36-42 with stock twins running 140 does seem weird...
That would be a very efficient boat!

UPDATE::

Well what do you know here is his 2009 run,says 130 though:

In Super Cat 850 D&M Motorsports, a home town favorite running a MTI, With Brian Haupt (D) and Dennis Hillhouse.

Exactly. I asked last and this year with no answer. No difference in my opinion, just allows guys to choose less competition class and get a win.

Now, if Pete Hledin/Randy Scism/Dave Hemmingson/Mike Fiore ran brand new boats, I would call them Manufacturers class. Anyone else in an open cockpit is Non-Pro in my opinion.

140 mph makes sense with 850 HP. With nobody using "S" engines in 36 - 42 cats it was probably the easiest way to put him in a different class so that he wouldn't be competing with the power adder guys that had way more HP.

Thats what I was thinking,brand new stock boats as delivered from the manufacturer,,,shows what I know!

Maybe back in 2009 the S stood for Supercat engines?

That number came from Jerry Sabatino and it was a 28' Nordic with a big blower motor.

We have a 24' BatBoat with a rebuilt "stock" Merc Scorpion. We had never been in any kind of race or Shootout before (other than a mudrun when I was in high school). Since we had a canopy, we were put in the Professional Division automatically, so that started us with a "P". Of course we had a V bottom so that gives us a "V". 24 foot long gave us a "1". Since the motor was rebuilt (just .030 over, but stock besides that), we were modified, so we added an "F". We have just one engine, so we concluded the alphabet soup with a "1". PV1F1 was our class.

It did not matter to us one bit what class we were put in, as it was just a thrill and a privilege to get to go down the course with my son that some mighty fine race teams had gone down before. We hope to tee it up again next year.

Bingo! When you're floating about waiting to run it's hard not to notice the mile+ raft up of boats...and then you realize that with all those spectators that you better put up a good number! And then when it's your time to run you're so focused you forget all about it. It is a cool event, thanks to all those volunteers that make it possible!
