I wouldn't have thought of it, but it would give the helmsman of a kite-driven boat a look at the apparent wind.

Seems like a bit of overkill... sizewise... for that purpose. But I can't think of any other, offhand.

Helps transform the upward lift of the kite into horizontal pull.

Just so.

What was the thing Ben Franklin did with the key and the thunderstorm?

Didn't he show that Galvani's frogs were powered by the same stuff as thunder.

Ahhhh... then the size is important and necessary.

Like a sentinel on an anchor rode.

Edit: Probably damps out some of the herky-jerkies, too.

It's sorta the same reason your mom always told you to wear clean underwear, in case you get in an accident. Always bring a big sock for when you're dismasted.

Upward lift? What is that?...2 degrees? Not much help seems to me.
It does add more "pull" though I think.

Increased Viability!?!?!
All of the above!?!?!
I'm asking!

The sock is attached to a line that continues upward. Likely to a kite or para-thingie. But the angle of the line is high enough that a change in wind vector wouldn't be immediately obvious, hence the sock.

I can see the sock indicating wind direction, not much help with wind speed, and, it seems to me, not anymore helpful then the flag(french) or that other piece of cloth there, whatever IT is.
I don't understand what that boat is DOING! Start mark?
I guess that was the original question.
