Everyone who has a sailboat literally learned nothing lol

As a sailor, I love to see this kind of stuff.
Another addition to this is that when a sailboat is moving at a certain speed, let's say five knots in 10 knots of wind then the sailboat is experiencing another 5 knots of wind against it because of the speed it's going. This is called apparent wind. So now that boat has 15knots of wind against it. When a sailboat does this and it happens on every sail on a boat if the boat is moving, then you have to pull the sail in to counter the apparent wind. This is because the apparent wind is coming from the direction that your boat is moving or the front of the boat while the real wind on a boat's preferred angle is usually about 120 degrees from the wind. Now your boat has its sail pulled in its wind angle is around 80 degrees even though the boat is pointing in the same direction. This can be repeated for a long while when you have the right sea conditions. This is also why you don't see the GP boats or the AC75s letting their sails out very far. They are trying to capture the apparent wind.

I'm fully convinced Derek is a smart enough man to understand that being deliberately slightly controversial, wrong, misleading, or incomplete about a critical piece of information sparks debate, which leads to his channel getting algorithm relevance as the source of it all.
It's my own little conspiracy theory as to why these "but actually…" videos keep showing up around correcting what was said.

Sorry, but this is the most confusing explanation I have ever heard.

A sailboat on a tack is running at an angle to the wind. The wind is always pushing on the sails. A sailboat never outruns its power source. That contraption is doing the same thing. It's running at an angle to the wind, otherwise it would be outrunning its power source. You cannot travel faster than the wind STRAIGHT DOWNWIND, only at an angle to the wind, otherwise there is nothing powering you. Forward momentum powering the wheels is not a power source.

Try making a fist instead of a palm.. will work much better. Maybe try the Vulcan shocker if only wan hand is available

It's just that the wind does not blow in parallel with the movement. The whole secret is that this is not shown on the video. And since it blows at an angle, the speed can be higher. The same with the model on the treadmill. At the beginning, the friction force is compensated by holding it with your hand. When the fan spins up, it creates additional thrust. Due to inertia, it spins. But over time it will stop.

It seems that you overachieved with the subscription count – it's currently running 1.73M.

Great video. Awesome explanation. No hand waving at all. I would argue that Your presentation was infinitely clearer than the similar video by the other author.
