ELI5: How can sailboats travel faster than the wind?
gpt
Sailing boats do not always use the sails on a boat like a parachute that collects the wind and gets pushed along. It sometimes acts like wing from a plane.this means with the right trimming the force pushing the boat along can be greater than the force that the wind would push it along conventionally.
