What is the fastest board trim, is it trimming like pic below, or more flat than A2 below, or does it depend on board speed and water state??

Fair go though,it looks like A2 is under full acceleration there.

Obviously thes guys don't sail back to the start of the course Only one harness line.Wonder why they don't ditch the boom arm as well?

Yeah they only have one side of footstraps aswell.

I also thought that the flatter the board was the better becasue that meant that the board wasn't as deep in the water. But now that think i about it, you just skim accross the surface anyway so the less of the front of the board in the water the better aswell. As long as the tail isn't sinking deeper becasue i would think that would make more difference than more of the front of the board touching water. Least possible drag is the way to go obviousily.

Hit by a gust??
Cant see the wind coming??
AA is such a srong bugger that he is just gritting his teeth and going big.
If we saw the next couple of shots he would have mast foot pressure back and just going f********k Im in with a chance here!!
The guy is hardcore, ask the guys that watched him sail formula gear in Melbourne when it was out of control.
Or then again, he might just be a pussy and backing off

Yeah yoyo you are dead right, I've been watching vids of speed sailing and looking at angle of attack, I've noticed that fast sailors usually only make contact with the back part of the board, expecially when the water is not dead flat, and since speed / slalom boards have flat rocker at the back, this must mean that the board is angled up slightly. I dont know how this translates to board trim or stance exactly, but I think I have been sailing with my trim too far forward. Can some bleedingly more experienced and fast sailors comment on this

He has also got an overhand grip on his front hand....maybe thats why he is so fast.

Wide grip, front hand close to the mast, I suppose "overpowered" doesn't begin to describe where this guy was at, on the edge. No helmet, huge weight jacket, no lycra suit like Finian had, I think Finian did have a one sided boom when he broke the record but it had extra reinforcing.

lol i got an overhand front grip aswell, but i'm not fast. Hopefully will be though.

got a big i've been taught to straighten both arms but if you look at speedsailing photo's or vids most bend there front forearms? i can understand the backhand trying to sheet-in but the front..i'm guessing to help trim open the sail in gusts

straight front arm was 10 years ago, I think it is keep the elbows pointing down for mast base pressure these days, or maybe he was scared and adopting a begginer stance.

even in slalom hiwinds most sailors tend to do these..well i guess you're right

all depends on the board, the sail, the chop, the angle to the wind you are sailing... so many things. I sail front had either way depending on the conditions. Boom height also changes. AA looks *really* powered up in that pic. I'd kill for conditions like that Its been ages at SP since we got a proper steady 40-50...

I want a definitive answer........ and I want it now!!!!!!!!!!!!!

i am thinking harness line length may be governing which way the hand goes
imo- long lines= hand over,short lines=either way
bit like hanging from a monkey bar
i know i alternate all the time except for when gybing when i always go hand over...
personal choice

And don't forget it was 4 degrees.. my guess he is just trying to hang on and lost all feeling in his fingers 2 hours ago.

There was a thread last year about trim..... or planing angle

Apparently the US Navy spent millions $$$$$$ determining what was the ideal planing angle for a powered craft.

Answer: 7 degrees

Try & maintain that at 45+ knots , with the canal's 6 deg air temp & 8 deg water temp
(& that's without wind chill )

another one! why such long linesthat's about 15cm more than what i'd be using! o.k. i understand again for gusts and more of a sit-down posture rather than way outslowie me i'd kill for just 20kts. in 4cm chop and wouldn't mind if it was minus 4deg.
