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 Webknot, in navigation, measure of speed at sea, equal to one nautical mile per hour (approximately 1.15 statute miles per hour).
