In contrast, the latter can slow down the vessel due to the increased drag and the need for more frequent course corrections to avoid capsizing or damage.

Depth also impacts speed. In shallow waters, the boat's hull may experience increased resistance from the seabed, leading to a reduction in speed. This is particularly true for larger vessels like Stena Line ferries, which have a significant draft. In deeper waters, the boat has more room to move, reducing the impact of water resistance and allowing for higher speeds.

Weather conditions are another critical factor. Calm, fair weather facilitates faster travel, as the boat can maintain its speed without the need for additional measures to combat waves or strong winds. However, in stormy weather, the boat's speed is often significantly reduced. High winds and heavy rain can create challenging conditions, forcing the vessel to slow down to ensure the safety of both passengers and crew. During such weather, the boat may also need to alter its course to avoid dangerous situations, further impacting its speed.

In summary, the speed of a Stena Line boat is not a constant value but varies depending on the water type, depth, and weather. Operators must consider these factors to ensure the safety and efficiency of their vessels, providing a smooth and timely journey for their passengers.
