It's a fantasy role-playing game.

DM: You are Jester Lavorre, a tiefling cleric . You are the member of the famous group of adventurers. Previously, Vera reveals herself to be a formidable mage, causing an Ice Storm which slows Nott, Caduceus, and Yasha and casting Mass Suggestion on the Guards to arrest them. Fjord, seeing the tide turning, summons a demon onto the ship to distract the crew while rushing himself to the aid of Caleb.
DM: Just so you know, this ship travels on an average pace of around 48 miles a day. Right now with the damage the sails have sustained, you're close to 20. You're less than half speed on the ship with the damage it's sustained at the sails. It's going to take you a while to get anywhere. But you have it.
Player: How big are the holes? Are they giant?
DM: They're beyond Mending.
Player: Okay.
DM: Mending can do little tears and things.
Player: No, I'm not talking Mending, I'm talking how big are the holes?
DM: For the ones that are damaged, the sails are mostly destroyed. They caught fire and burned.
