It would probably go backwards, but the tidal flow would be stronger. The reason being is the fan accelerates the air towards the sail, but there is loss between the fan and the sail due to turbulance, hence the fan is the stronger force. The best you could hope for is to remain stationary.

If the fan was on the yacht, roughly opposite the direction of air flow from the fan. Little of the thrust imparted by the fan to the air is transferred to the sail.
If the fan is not on the yacht, then any direction it could sail if the resultant wind was natural.
If the yacht is aground or tied to the dock, nowhere.
If the yacht is being towed, whichever way it is being towed.
If tide or current is the dominant factor, then whichever way the water is moving.

The fan would pull the boat backwards as the the air would go forward and have a reaction in the opp. direction. Also the air thrown on the sails would try to move the boat forward but while reaching the sails much of the energy of the wing would get discipated and also due to elasticity of the sails the pull made by the reaction of fan would be greater than the action of wind on sails.....thus the boat would move in the direction opp. to the direction in ehich the fan is throwing air.........simple physics...aint it

Why don't you just lean against the mast and see if the boat moves? Same principles apply...
The boat will just stay where it was when you start the fan.
Take down the sail and blow the fan off the stern an you will go someplace.

enable's say you pour one thousand watts of potential into the fan. 2 hundred watts is misplaced as warmth, so 800 watts of potential is spent accelerating air forward, proposing an equivalent thrust to the boat rearward. The air mass donning that potential heads for the sails. perhaps a third of it particularly is converted to forward thrust to the boat. The opposite thrust wins definitely, and the boat is going backward.

Oh my, that's a doozie question. Just think of it being the wind on a windy day. If you can sail, you will understand.

Whichever way the tide was flowing.
