The present invention provides a vent mast, comprising: a fixed pipe connected to a fuel tank provided in a hull and disposed to be protruded from the upper part of the hull; an elevating pipe connected to communicate with the upper part of the fixed pipe and provided to be able to elevate from the fixed pipe; and a driving unit for raising the elevating pipe to discharge a boil-off gas in the fuel tank to the outside through the elevating pipe when the pressure in the fuel tank increases by more than a certain level. In the present invention, the vent mast, specifically, the upper pipe of the vent mast is configured to be able to elevate. When the boil-off gas is discharged, by raising the upper pipe of the vent mast to a predetermined height above a cabin, the boil-off gas can be discharged at a location spaced a predetermined height from the top of the cabin. Thus, the vent mast can promote the safety of crewmen in the cabin.
