I was just thinking that 80-85mph was achieved by nick barsh in a p18 with 200 hp, but point taken, it alot heavier and a p18 would be dust in the chop

Yeah, the 18 really is an ironing board compared to a V24. not sure of the exact weight of one, sure tricky could tell though.
They really are supernatural when it roughs up, never underestimate their capability, you could embarass yourself (I mean by trying to race one, going back to my original post)

There not to bad in the calm either, the race last year at Bournemouth had tricky holding off all maner of boats including a P1 style Sunseeker/Buzzi 2000xs, now that was a good race don't know what his average speed for that race was but it must have been good for a V24

On Sunday the v24's seemed to punch there through the rough water, they are just brutal in the rough, looked excellent.
They dont seem to back off in the rough.
Why did they stop running, i know one had a g/box problem.?

What about a v24 vs a p25? apperently p25's are pretty good in the chop?

As much as I love the Phantom brand, the V24 would wipe the floor with a P25 given the power to do the same speed, ie, V24 as is, P25 175/200s similar top speed, but in the shitty stuff, the V24 would be off. They are phenominal.

When did Nick do 80 - 85? We did 76 max with a Raker in the 2000 championship winning boat - of course Nick wasn't racing then! The only time it did anything like those speeds was with a 2.5EFI (260hp) on the back!

The V24 hits the water at about 1580kg and leaves the water at about 1495kg if the math was done correctly.
It burns about 1.6 litres per mile.
It does not really matter too much the conditions impacting the speed, You loose about 2 miles an hour in the rough.
I left the second race at Torquay after the second lap, as we had petrol coming into the canopy cockpit, and that was disturbing us. We were the 'second start' in the two start race, the class 3C boats leaving about 2 minutes before us. Due to the specific type of rough, I had passed every single boat before the halfway point of the first lap ( excluding the start run ). The V24 specifically likes that type of rough in relation to other boats.
On some sections of the second race we were doing 74mph, averaging 73mph, and peaked at 75mph. On the previous day, in 'flat' conditions, we were doing 75mph, averaging 74 and hit a peak speed of 76mph.
So the boat itself seems quite consistent, despite the sea state..

Correct.
They dont behave nicely at mooring speed, they sit too low in the water if not on the plane, and you get wet, they are very hot inside, the seats are bolted directly to the floor and you feel every single ripple, they are an odd shape and can not be tied up without bumping something, they get water up the exhausts and into the engines if someone looks at them, and basically it is quite cramped inside there.
I race with Ana, who is 5 foot nothing, 40kg and her seat is pushed right over to her side of the canopy. Two real grown men cant fit inside. I had Geoff inside the boat, and his bulk was getting in the way of driving all the time.
Not a pleasure boat at all.

I too would like to know when a P18 did 80-85 with a 200. I can only average 86.9 on Coniston with a 2.5 EFI 260 on a P18.

I'm pretty sure it was a P19 not an P18 and am sure nick told me he could achieve over 80mph with a XR2

To be honest, you need to get the speeds from an official timeed run like Pier to Pier or Conniston. The rest is not reliable, or 'thinked' speed.
When we race now we have a completely seperate GPS system ( actually two of them ) and they track our speed second by second, taking 60 measurements a second, and logging once a second. Part of the big gps is a 3 way inertial meter system that monitors stuff like drift etc when we corner as well as the GPS location ( taken from an F1 race teams test setup!!)
So we have a very accurate idea of our cornering speeds, flat out speeds and overall performance. We then review our race later to see where we messed up, and try to improve. There is an ability to link in the video feed as well, so we can see the reason why we did stuff that we did. It is a great learning tool.
However, from time to time the single speed measurement for a log places us at over 90mph for a single second, then at 60 something mph in the next second. Something to do with 'missing' the GPS signal or getting an incorrect reading. We know this occurs and if you average out a series of readings, you get a proper reliable speed, which matches what we see on the navigational GPS.
The point is our equipment reads 60 times a second and averages it out, and still gets it wrong. The typical GARMIN navigation GPS takes a reading once a second. So the chance for a GPS to 'overread' a speed is higher. All it takes is a small interfearance in the GPS sygnal and the boat is slower one second and aparently faster in the next second, due to the misreading.
We can download the last 60 measurements that the GPS takes, as they are still in the buffer, and we see - at standstill - up to 20 cm differential in that single second. GPS is not exact, it is very precise, but not exact. Being out by 5 meters is acceptable. But if you are using a GPS to determine your top speed, it is not reliable.
