WebKnots Measuring the knot in the 17th century. Knots, on the other hand, are used to measure speed. One knot equals one nautical mile per hour, or roughly 1.15 statute mph. The term knot dates from the 17th century, when sailors measured the speed of their ship using a device called a “common log.” WebShip slip is the difference between the speed of the Engine and the actual observed speed of the ship. SLIP. Slip = 100% – Efficiency. Where, Efficiency = observed distance covered or engine speed. If the engine speed cannot be read due to rough weather, then observed speed in nautical miles/hour(NM/h) can be used. Apparent Slip
