New Class Of Racing

[Admiral P. Brain]

nice old blue hp 500 in a extreme 26
or yanmar 480hp on bmax
which ones faster?

[Rockey]

i would think a 26 ft cat with a pair of 225 ho e/rudes would be very quick, raffshore ?? skater, or a good old 28 p for the rough,
right flights to malta




only kidding jon

I think the HP to weight idea is great. However their r lots of twin boats(especially inboards) that exceed 500hp. As discussed Gary,
I would be very interested in entering this type of series. However I would also like to run as a true super sport boat in P1 next year. As I knew and everybody saw at the weekend I am running 160hp under for my weight. I will be running twin 300 opti XS's next year. I know of a couple of other people thinking of doing the same. It would be a shame to exclude me & them.

Would be better if the new national series did not clash with P1 dates. The new series would be a great testing bed & skills sharpener for us Brits to beat the Italians.

Would the series be open to Uk teams only?

Just some thoughts.

Cheers Paul

What about V24 thats close to what you describe just need to up the power & add an outboard division

[flightracingteam]

In response to the people who it would seem would like to run even more H/p than 500, and theres quite a lot of you. we believe that we can add a larger class within the new concept this would be min boat lenght 28 ft max boat lenght 37 ft
Max H/P 1000 either inboard or outboard max 2 engines power to weight ratio 4.5 Kilos per H/P. This would be the hot boat 1000 class with the original Hotboat 500 class min boat length 23 feet max H/P 500 single or twin inboard or outboard Max boat lenght 29 feet power to weight ratio of 3 kilos per h/p. This is the minimum weight, but the boats can weigh more but not less so the min weight for a hot boat 1000 is 4500 kilos and the minimum weight for a hot boat 500 is 1500 kilos.

[flightracingteam]

POWER TO WEIGHT CHART FOR HOTBOAT 1000

500HP MIN WEIGHT AT 4.5 KILOS PER HP 2250

600HP MIN WEIGHT AT 4.5 KILOS PER HP 2700

700HP MIN WEIGHT AT 4.5 KILOS PER HP 3150

800HP MIN WEIGHT AT 4.5 KILOS PER HP 3600

900HP MIN WEIGHT AT 4.5 KILOS PER HP 4050

1000HP MIN WEIGHT AT 4.5 KILOS PER HP 4500

[KINPACIFIST]

This sounds good

[flightracingteam]

POWER TO WEIGHT FOR HOTBOAT 500

THERE IS NO MAX WEIGHT BUT THE MIN WEIGHT WILL BE 1500 KILOS

[KINPACIFIST]

surely HP to weight ratio stops the eggshell builds. or am I missing something.

[OCRDA]

What about a Smaller Class ?? Say 21 ft / 200hp ??

[flightracingteam]

MIN BOAT LENGHT FOR HOTBOAT 500 WILL BE 23 FEET MIN WEIGHT 1500 KILOS MAX 500 HP

sounds like 3C / Formula 200 to me

In response to your question IS THE SERIES OPEN TO UK TEAMS ONLY, the answer is no if they have the boat we have the water!!

[Cookee]

What about TV? IMVHO the best way of atracting entries is to offer TV coverage!

[verytricky]

Just a question...

Where did you get the 4.5kg per hp from for the minimum weight?


If I ran the V24 standard - as under existing class rules - I would have to add 200kg to the boat to meet your minimum standard for weight... If I used a 500 hp engine to get really competitive, I would have to add a ton!

Given that a 500hp engine would use ally heads, the engine weight would remain the same, I would prolly sink the boat adding one ton of weight.

The current V24's run on a power to weight ratio of 3.9kg to each HP. They can be powered up quite easily to where they run ( as in the USA ) 480hp at a power to weight ratio of around 2.75kg per HP.

A nice round number like 3kg per HP would be simple and IMO quite workable. This would mean that with 500Hp I would need to add 200Kg to the V24 to make the minimum 1500kg rule.

Or am I reading it wrong, and this only applies to the boats bigger than 500HP? So the minimum weight boat for the 500 class is 1500 and the maximum HP for the 500 class is 500Hp. Then if you want to go bigger than 500HP you need to apply the weight rules?

[OCRDA]

I think you will find that Power - Weight Ratio is a little difficult for the average Powerboat Racer to understand !!
Does your proposal inc crew weight ? Prior to Race ? or After a Race ?

[flightracingteam]

Verytricky the power to weight ratio is for the hotboat 1000 for the hotboats 500 it is just a min weight of 1500.

OCRDA the weight is for the boat engine and equipment ready to race no fuel.
Hope that answers your question Bob

Cool - thanks.

So if we upped the engine to 500Hp, we would add 200kg of leadshot, and thats it. Nice.

Possibly I would add 200kg of re-inforcing to the hull - given the breakup the boat seems to get in the rough... I delaminated the left front again at Cowes..

[flightracingteam]

Tricky

That is absolutely right

and oops about the delamination

[roofer]

My cat could make minimum weight, but I could not get below 520hp even when ive removed the engine mods, is the 500hp not flexible?

I also know of a p25 with twin 260 offshores that would be interested but again is over the max hp.
