Transferred forces on a sail

IMG_20250612_224608.jpg


1 wing constructed with 3 elements, very good for high angles of attack, nice air-craft

If the angle of attack is very small, then a single-piece wing is better.

OMG What's this?

Something very strange from an Aero-Nautical point of view.

This isn't 1 wing, but many sails: a ship-with-sails. Maybe it's 2 wings. I don't know.
 
knots x knots x 0,16 x m^2 =

m/s x m/s x 1/2 x 1,2 x m^2

Hmm missing bits of the equation, that is how they sink boats.
Thanks a lot teacher. I might need reading glasses or more focus

1 Sail

1 Wing built with 3 pieces (Jib + StaySail + MainSail)

My sail plan as posted is a main and jib on the same (wish bone boom) a so called Aerojunk. I guess you already know this?
So yes as you said one airfoil.

I thought I could use the tension of the sheet (after catastrophical wrong calculations) to adjust the camber of the main by automatically tightening/easing the leech.
So that has to be done manually under sailing. (Still same system)

Maybe it still could be auto, but for that I need to know what the real tension of the main sheet is under various wind forces.
