If your boat has good lateral resistance (a big keel or centerboard)
this force will be nearly equal to the sideways force.

I think that things are a bit more complicated than this.

The boats that have the best performance to windward usually have fin keels.
Fin keels have a smaller area than long keels, don't they?

I think that this conundrum demands an explanation from an extremely
intelligent engineer. Jax ... here's your opportunity!
