Another thing to keep in mind is that sheeting angle is also determined by the position of the mast.
The clew might not move but if you pull the mast towards you, you are also effectively sheeting out. Even worse you have now directed the lift of the sail upwards and you take off, just like the guy in the youtube clip above.
Never let go of your equipment, that will just make things worse. Instead pull on you backhand and you either make a little jump and sail on, or you'll make a partial forward loop and land on your back without any issues.

Yes, it is tail walking. The early stages of tail walking is much as you describe, but the nose is lifting and with enough speed and wind (+ apparent wind), the board will take off. Almost all boards will do this in the right circumstances even with a small fin (wind speed, smooth water, wide board, sailor weight, size of sail, point of sail (beam reach or higher).
With enough skill to hold down a 7.5 on a beam reach on a 135 L board in 30 knots on flat water with a 40cm fin, a 90 kg sailor will probably stay on the water, but a 70 kg sailor will be in the air.

Is that tailwalking?
I tought tailwalking was more when the board starts to oscilate from right to left and lift you over the water and the fin. The board nose doesn't raise much more than the back. You will get the nose up if you open the sail tough. This is how I get out from this.
This is caused by too much lenght of fin and maybe by a flexible fin too. (7.5 sail, gust of 30kts on flat water, 46 cm fin on 135l freeride board). Switching to a 40 fixes it.

As PG said...........
On wide boards, hitting the "lift off mode" can be achieved pretty easily. Sheeting out is disaster, so it's counter intuitive to keep the power on, but you must keep powered plus downward pressure on the mast base (hang your weight in the harness). Yes, move the base further forward in the track, it will help too as well as a smaller fin.

No need to change anything. These things happen when you are on the limit, that is just a fact of life.
I did something similar the other day when a mega gust hit the sail, it probably opened the sail a fraction. The good thing was that I managed to unhook while going nose up, and then just let go of the gear. Less damage that way!

@markh: I was reaching, deck plate right in the middle, it's the carbon version that I have
@mcross and remi: could be that I had too much back foot pressure, I was going really fast. So you guys advice not to go smaller than a R13 56 ? What about a stiffer fin ?
@Unregistered: yes that are the classics, although I think that my boom was not that high

|Unregistered||reduce your fin size ,, lower your boom ,, bring the mast track a bit forward ,,|

For 8.8 is better to go to 56cm fin but this also can happen for different reasons.
In this case a big gust coming from more back in the video that make the guy open the sail and loose pressure on the mast foot, typical crash.
Difficult to give more coments with out seing the action but for sure small fin will help you.
All the best

Sounds like you just lost mast foot pressure?
If I am well powered up I now use a Drake R13 56cm fin with my 8.6 Severne Turbo and I weigh 86kg.

|mark h||Hi Bel, were you sailing up, across or down wind? Where do you have your deck plate in the mast track? Is your US147 carbon or wood?|
