Mast (vertical, leading edge of sail), Boom (horizontal,bottom of sail), and a spinnaker pole if you use a spinnaker which is a sail type
A mast. Although it is attached to a mast the thing that holds a sail up is a halyard. a mast is something that pushes the boat with wind and the reason its called a mast is cause it holds the biggest sail, the thing your looking for is something that is on the bottom of the boat and runs vertical on the boat. if that gets ruined the boat is ruined, unrepairable
The vertical post to which a sail is attached is known as a mast. However, on the historical tall ships, the sail is attached to a horizontal beam known as a spar or boom. Some might say that the wind holds a sail. Or perhaps you are referring to the piece of rope (or line) that controls a particular sail. Please be more specifical.
