Awesome Session MT Congrats on your PB!

MT your a freak, sensational U-Turn Happy Days  

Nice set of numbers MT and a super turn and burn pb

Wow. Smokin MT. Well done.

Thanks everyone. It was good to get a PB again.

Almost a 27nt alpha unbelievable, you must have been the only one out as the car park was empty when i left

Fantastic effort Mark. Nothing short of brilliant sailing mate.

Amazing PB Mark! - Congrats.

Real Speed calculated your 2 sec at 42.0 kts and alpha at 26.9 kts. Just mega!! Your acceleration on the 2sec run was phenomenal (but still believable!)

Thanks for checking it on Real Speed Bushy. Yes it was a quick burst of power before I had to gybe. It was getting shallow and the trees were approaching very rapidly.

Keef, only one car in the car park at 4:15pm,  Michael was just heading out, Detlev came down for a chat, and then two kiters turned up later.

Awsome sailing there Mark, well done.

Well done MT! Thats a smokin turn mate 

Great numbers MT. Both GPS Action Replay and GPSResults give you 42.57 knots for 2 seconds. But looking at the track and the data, this 2 second segment looks suspicious. You accelerated from 31.9 knots to 42.38 knots in just 3 seconds, and then dropped from 40.22 knots to 19.94 knots in 3 seconds. Your angle to the wind is very deep - 164 degrees, almost dead downwind. During your best alpha, your speed had dropped to 27.97 knots when you reached the same angle (which is much more realistic, unless you got hit by a killer gust just as you went into the jibe). Chances are that ka72.com invalidated the points due to an acceleration filter. Here's your 42.57 knot section:

The top alpha is close by:

For reference, here's the 41.57 knot 2 second section from your track:

Thanks Peter for having a very detailed look at that data. 

Just to explain the bearaway.

I did feel a very aggressive acceleration as I beared away into a black 35kt+ gust. The water was flat and I was using a 6.4 sail and a custom 4kg speedboard, so accelerating is something that board does very well. I was running out of room very rapidly and it was also getting very shallow so I went into a low laydown gybe. My boom and sail caught the water and stopped me very quickly so that may explain the quick decceleration.

Thanks again for the feed back.

Happy sailing.
