that skiff stuff looks fucking dangerous, if you dont mind me saying so.

what doez the hull of your boat look like? these skiffs seem to be cut off square at the rear, although i cant make out the shape at the water. a square back might or might not cause a low pressure zone that would slow the boat, depending on the angle of closure. motorcyclez have a serious problem there.

are the shapes rwquired to be tge same by the rulez?

Yes well, all this isn't for you now, is it?
Have you considered taking up knitting?
Ouch. Truth hurts, Dude!
I always fancied the idea of green bowling when I'm too infirm to do anything fun. Past that, I'd never given thought to a seated activity. P'haps spend more quality time with my tropical fish???
Knitting isn't out of the question...

changing the shape of the aerofoil is an intriguing skill. in an aeroplane its fixed, all you can do is mess with the flaps, and thats a low speed thing.

but on a boat its all up to you. amazing.

do hi tech yacht racers use wind tunnelz to dezign their boats?
Mostly done with computer simulation these days. No expense spared though - these things are spacecraft!
Check out the new AC75 design for the 2021 America's Cup. Solid sail, foiling monohull yachts:


However, this below is the pinacle of racing for me - 18ft skiffs:

Got in a tangle while baring away and resetting

what does ^^this mean?
Got in a tangle = exactly as it sounds - got tangled up in my ropes.
Baring away = turning from an upwind heading to a more downwind heading. Boat is much less stable when travelling in the same direction as the wind. The transition during baring away can be dicey in a blow.
Resetting = adjusting the sail settings to make more efficient use of the new direction of wind incident on the sail. (mainsheet (adjusts angle of bottom of sail relative to wind), kicker (tightens the sail leech, increases mast bend, reduces sail twist at top of sail) cunningham (flattens the sail luff), outhaul (flattens the sail foot) and centreboard (keeps boat in a straight line, but sometimes just causes drag) need to be adjusted).

Sounds impressive, probably, but the reason I'm not a great sailor is that I don't fully understand the interrelationships between all of these settings in relation to wind direction, wind speed, my weight, body position, sail design, draft characteristics, pitch and roll angles etc...). I can follow the fundamentals and that keeps me in the game, at least.
