How do you sail a boat?

---- How to sail

The tiller

Push the tiller away to go away from the wind and pull it if you want to head towards the wind. You cannot head striaght towards the wind

The sail

Pull the mainsheet in if you are heading as close to the wind as you can - a beat

Let it half way out if you are heading side-on to the direction of the wind - a reach

Let it all the way out, so it is at a right angle to the boat, if the wind is behind you - a run
