To put in perspective its faster than either a Tornado or a foiler Moth has ever been accurately timed over 500metres. Its also way faster than has ever been recorded by any means for a low rider Moth, and, delightful a boat as the 300 is, its not in that territory either...

I'm a big 300 fan and find that speed quite preposterous. There's no way I'd believe that speed without a full GPS trace to convince me. Recorded as a max its just got to be a glitch.

I'm quite sceptical about it myself although being fair to the guy who did record it, he may have just caught that right wave at the right time. I'm also quite sceptical about some of the yachtie results as I've whizzed past like sport boats in pretty extreme conditions and they have seemed to be standing still. I'm also a bit scepticle about this "catching the wave" theory, as when we're going fast, we're going well in excess of the wave speed. Possibly a wave generates a rapid rate of acceleration, which is recorded by the GPS, but whilst the boat reaches top end speed, the GPS is still reacting and therefore still reacting upon the assumption the boat is still in acceleration mode and records a higher untrue speed as there is a delay between when the boat actually stops accelerating and the GPS actually picking up upon that fact, hence spiking.

I'l be expecting 300's to be getting top results at all the big handicap competitions this year then.

After seeing it i did belive it i was watching from the shore after coming in
early i know i am a pansy but het he is lardyer then me. It looked very fast
and very scary well done Geg

I used to own an RS 300 and I'm over 13 stone in the kit. They cannot plane upwind in the proper meaning of the term. They can maybe go at 8 to 10 mph "upwind" at 80 degrees offwind; so can a Laser. But that's no good for Vmg.

I now sail an RS 600 and upwind while actually "beating" in the RS 600 I can easily make 7 to 8 mph on the tack while making nearly 5 mph Vmg. In the RS 300 the best I could make was 6 mph on a tack and V mg was under 4 mph. The best Vmg I could make in the RS 300 was about 4.2 mph and that was by pinching!

Sailing the RS6 the "max" speed on the GPS unit I have recorded on a broad reach in about F5/6 was 23.5 mph, and I believe that was a spike, although I have measured 21 mph "max" a few times. In my view all the "max" readings are spikes.

Have got to add my scepticism to that speed too- I've had 22 knots out of my 600 on peak speed on a Garmin, but having since sailed and checked the track logs i really don't trust it!!
The conditions at the nationals in Looe when this was recorded were pretty special- big long waves to surf and some monsterouse breeze, but still can't help feeling going that fast in a 300 would result in a mild case of death.....

I agree, at both the eurocup and the nationals I overtook 300's with relative ease on all legs in my 600 and the best i could manage was 20.8 knots.  From doing a lot of speed runs in my 600 i reckon a heavy person could maybe push 23 knots from it (any more i wouldnt believe to be anything other than a glitch) so for a 300 to get 24.7............im not even slightly convinced. 

sorry fizzicist. 

Doug
p.s though of course i've only come to this conclusion from what i see, not from any substantial evidence.
