Forces on sails (3 m) = 5-m/s (≈10-knot) wind at 3 m above the water would be approximately "V" (15 m) = 6 m/s (≈12 knots) at 15 m above the water. In hurricane-force winds with "V" (3 m) = 40-m/s (≈78 knots) the speed at 15 m would be "V" (15 m) = 49 m/s (≈95 knots) with "p" = 0.128. This suggests that sails that reach higher above the surface can be subject to stronger wind forces that move the centre of effort ("CE" ) higher above the surface and increase the heeling moment. Additionally, apparent wind direction moves aft with
Man-of-war Man-of-war The man-of-war (pl. men-of-war; also man of war, man-o'-war, man o' war, or simply man) was a British Royal Navy expression for a powerful warship or frigate from the 16th to the 19th century. The term often refers to a ship armed with cannons and propelled primarily by sails, as opposed to a galley which is propelled primarily by oars. The man-of-war was developed in Portugal in the early 15th century from earlier roundships with the addition of a second mast to form the carrack. The 16th century saw the carrack evolve into the galleon and then the ship
