I've just downloaded it, and had a look with a video editor. Woody does it much better than me (5kts this day), although the sequence looks similar.
I haven't got time now, but later I'll extract the Woody sequence, and post. And yes the nose does rise slightly, but only for a frame or two.

Figured out a while back that all my gybing issues are from PEBAB

Woody sequence.

You can see he's going faster than me by his rooster tail, (although I guess he's a fair bit heavier and displaces more water.

Sail is coming up prior to flip

Feet unchanged as sheeting in starts

Old front foot moving back, and I think new front foot is in it's strap.

Back foot now in, and a few seconds later, ------

hooking in

you can see the raised body to line hook up with line.

Then he's away!

Latest video from Albany Nov3/4. Initially I was just trying to get a few shots of Woody's Alphas as he is on mission to crack 30 but a few other sailors in there doing some nice Alpha's including Decrepits very tidy effort of 23.7 and Rondog (27.47), Stretch (25.66) very smooth turns. Somehow I completely missed Dodi who just beat Woody's Alpha of 28.441 and quite a few other sailors (Jay, Boz, Antman and probably others) pulling 25+ Alpha's I missed getting good/any shots of. My lowly efforts (the POV shots) were around 22 with top of 23.5 as my cross wind speed/speed in general is terrible. Despite checking the tune in this video prior to uploading it unfortunately blocked in the US so you will have to use VPN to watch there.

Thats great footage but what impressed me most is your flying skills, FPV? What drone do you use?

Drone is off the shelf DJI FPV with all footage in sport mode as too chicken to sail in manual mode yet over water.

Not up there withthefastest, but one of my fastest @ 27.75Kt Got it on the helmet cam with telemetry.

LG, 2022

?feature=shared

BTW. I also do a variation of the strap to strap Gybe where I flip the rig before switching my feet, but I put the back foot in first coming out of the gybe to keep the fin driving.

This one felt nicer but was slightly slower @27.4 and I have not found the telemetry to add yet. The look back before the gybe is line up my exit angle with something on the far shore:

I would get bored after a few runs sailing on such flat water.

Flat water is good but not all the time.

Depth of water looks shallow in the second video so i am guessing you were using a delta fin.

No grabbing the mast on sail rotation which is easier on flat water i think.

The 80 odd speed sailors ,who drive thousands of kilometres, to make the yearly pilgrimage to Lake George each January to March, might not agree

Nothing like planing and gybing in glass.

That is because, that Lake George exists in a different reality, where its Earth is round... so those sailors dont get bored.

The reality of which Pcdefender exists, the Earth is flat - its very boring in that reality.

Planing threshold in jibes is somewhere between 6 and 8 knots. 8 knots is clearly planed through on a slalom board; 6 knots means the board never really sank down, and it looks like a planed through jibe to observers. Small speed boards may have somewhat higher numbers. These numbers may seem low, but keep in mind that the lowest speeds in a decent jibe are usually just for a couple of seconds or less. Often, it's just a single point, with nearby points being 0.5 to 1 knot higher. Measuring at 5-10 hz instead of 1 hz will typically result in a 0.5 knot drop in reported minimum speed.

As Kato said, very good jibers often have minimum speeds around 15 knots. Here are the jibes from his 29 knot hour this year on Lake George:

The best windsurf jibes I have seen in GPS tracks are from Slowboat this spring in Albany, with a couple of jibes above 20 knots minimum speed:

In the data above, you can see keeping 50% of the entry speed in jibes is very good for windsurfers, and 60% is outstanding. With a foil, it's easy to keep a lot more of the entry speed, even in much tighter turns and chop. Here's and example of an average session from a good winger:

At my spot on the gear i'm on, they will never be fast fast and far from the fastest ever, but working toward 50% is a good goal for me now learning to jibe. That turn analysis feature is great.

Grabbing the mast ???? Not sure why you would do that. BTW LG is just one of the epic spots in Aus and yes I enjoyed the swell line of Safety Bay. The only way to improve your windsurfing is to get out of your pond and explore the world.

I don't get bored in the slightest little bit. Every day and run is different and there are always challenges. It's a big lake and there are always other places to explore.

For many years, year after year, I have spent up to two months sailing there, day after day, and loved every minute of it.

The water is not as shallow as it looks. Most of the places we are sailing it is a meter to 1.5m deep, but still very flat.
Minimum depth we usually sail in is around 30-40cm deep. The depth varies very gradually, so it is quite safe and we very rarely run aground if we are sensible.
And yes, we mainly use 50 degree deltas, or 40-45 degree rake weed fins, depending on the state of the weed each season.
I have no time to grab the mast in gybes. It's too slow to do that, and not that easy to do with a Cammed sail with a zippered boom cut-out either.
