It could have been a very instructive session howevber it isn't as you do not dwell long enough on the earlier examples. The outcome of that mehod is almost invariably that
watchers think they understand...but soon afterward they forget. To assimilate knowledge takes time and true conciliation with all details.Even the explantion of 'lift on an
aircraft wing was truncated....the concept of lift frrom the keel was rushed through. That makes it seem like some religious spruiker rushing one to donation point by a
sort of mesmerisation.The proximity and shap of sails is also important in 'movement'...I wrote this at your 13:51 so now will see-out the rest.

When it comes to demonstrating the effect of the force created on the profile in a stream, I prefer an ordinary soup spoon with its convex surface close to the stream of running water coming out of the tap. You can see and feel it. No appealing to Bernoulli's law or looking at the wing of a jet-powered airplane.

Can you slow down please? Maybe telling people what they need to do first and explaining "why" later for people with very little physics experience.

The force vector ratio from width of the boats is the trimaran and catamaran design. A catamaran should be built in have a force vector ratio that is three to one. HtoV. The horizontal force you can capture before the boat heels and you lose wind power.

The surge of lift is greater than the power of jamming.

The keel is in the wrong place. The keel should be at the mast. The following edge of the keel matches the following edge of the mast. This on keeling.

When will not keel the mast and headsails to sail upright and faster? Stem to stern keel line or wing keel and blade keeled head sail. What if you keel the mast accurately at the mast and remove the unkeeled headsail?

Why is that sailboat model so beat up? and its got a wood screw for the front bearing lol
