You are quite right Mr Wolf, its was at the Nationals when on one of the reaches the fastest boats did the mark to mark 1.1nm in 3 minutes = 22 knts and the slower ones did it 4 minutes.

I think the dicsussion is about top speed. I have no doubt a PT is waaay faster round a track than a sunburst.
However, if a PT doesn't plane, and a sunburst surely does, you might find top speeds aren't much different?
thats like saying that georgia is faster than groupama 3 because georgia can plane but groupama cant.
No its not. Not even close. A PT is about 14ft, and for a multi, has relatively wider hulls. If it was lmiited to a hullspeed to due to length/width/shape etc, I was thinking it might be more limited in a possible top speed then an out of control sunburst on the burst.

Hmmmn, you waited 5 days to make a post like this on a Saturday night with no information that you didn't already know 5 days ago?
I know where you are coming from but that 1.1nm could be, well anything right. And the 3 minutes might be nearer 3 minutes and 10 seconds, or whatever.
All it takes is a photo of GPS max speed (done honestly of course) and it puts the issue to bed.
Hopefully the top speed is higher than 15 knots.
But 22 knots ? You have to be joking (where is the bullshit bell)
If this thread was about PTs vs Javelins or something similar it might be worthwhile, but having raced a PT around the same track as Sunbursts for nigh on 20 years I can't recall one going past me on any point of sailing, or even getting close.

You are a hard man Tim.
I met the guys on friday night at the club I asked about the speed, the distance and time was mentioned.
By the sound of things photographic evident will be the only thing you will believe.
I will take my gps out every race in the new season.
One thing for sure the PT is a lot faster than the sunbursts I used to sail.

What is the top speed you ever reached in your PT ?
It's not bullshit because of lack of photo's... It's bullshit because of the method used to calculate speed.
1.1nm in 3 minutes is indeed an average speed of 22 knots.... But, how do you know that the distance wasn't 0.9nm? Then the speed would only be 18 knots.
As for a motorboat running alongside.... Is it getting it's speed from GPS, or from the prop speed? If it is from the prop, then the speedo will be tuned in flat water. The conditions needed for a PT to do 22kts means that there will be "slip" so prop speed will be higher than actual speed. Even if it is GPS, it is the speed of the motorboat, not the PT.
I personally don't doubt the PT's can do 22 kts in the right conditions, so please let us know when it gets recorded on GPS.

All the marks at Napier are laid to and by gps co-ordinates, so the distance would be fairly close to the 1.1 nm.
The patrol boat was anchored at the top mark and timed the boats rounding it and when the boats gybed at the wing mark so the time would reasonably accurate.
As per SA..... "photo or it don't happen"
So we will have to wait for the next season and a good NWly.

I think a New Zealand bloke built all/most of the Rarotonga sunbursts. Can't remember what his name is but had something to do with the sailability at evan's bay YC a while back.
