Ships and boats have various design limitations, and going beyond certain speeds can result in increased fuel consumption, reduced efficiency, and safety concerns. While some ships can exceed 30 knots, they are often designed for specific purposes and may not be practical for all types of vessels.

Why is a knot called a knot? The term “knot” in the context of measuring speed on the water comes from the traditional practice of using knots tied in a rope to measure the speed of a ship. Sailors would let out a specific length of rope with knots tied at regular intervals, and they would count how many knots passed through their hands in a certain amount of time to calculate the ship’s speed.

Why do ships use knots instead of mph? Nautical miles and knots are commonly used in maritime navigation because they provide a consistent and easily calculable system for measuring distances and speeds at sea. Using nautical miles and knots ensures uniformity in international maritime communication and charts.
