If you are standing on a ship doing 20 knots, how fast would you have to move yourself forwards, to experience the water moving past you at the same speed as it does if you are standing still on a ship doing 28.5 knots
You're going to say 8.5 knots... which is 9.7mph.... so I think that is the equivalent to someone sprinting fast? So if you sprint forward and look down at the sea (not wise...) you'll experience the ocean going past at 28.5 knots.
