Full Power!

 is a ship ability in Sunless Sea.  allows the ship to move faster than its normal maximum speed for a short time, at the cost of additional fuel consumption and gaining the status effect Peculiar Noises. This effect has a chance to cause the Fire! event.

Upon pressing F or clicking the flame icon on the bottom of the interface, engine temperature will gradually increase, as though the crew of the ship had stoked the boiler. Over 200 Engine temperature generates additional engine power and consumes more Fuel. Engine temperature will both rise and return to normal in a gradual manner after the current barrel of Fuel is fully consumed, as if the captain had ordered crew to stoke the boiler, rather than toggling between two discrete binary states. To maintain Full Power! speeds, it is necessary to press F or click the flame icon again when engine temperature drops back down, either after depleting the current Fuel barrel or cooling naturally past 200 degrees.

Upon using the Full Power! command, the player gains the status effect Peculiar Noises. This status effect has a chance to cause the Fire! event while it is active and engine temperature is still hot. Equipping a Caminus Yards Avid Suppressor to your ship's aft slot will prevent the Fire! event from happening, but will not remove the status effect.

Full Power! is useful for reducing Supplies usage at the cost of increased Fuel consumption. Upon obtaining a Caminus Yards Avid Suppressor, Full Power! can be used without significant risk.
