I'm talking about a very simple thing, a map of the ratio between the height / period in cm / s, are data that you already have

height/period

These two waves have the same height but the one with the shorter period has a greater slope and a greater shaker effect, 0.528 cm/s against 0.336 cm/s

Good morning, considering that the shake effect on the boat depends on the slope of the wave and not on the height; Is it possible to insert a map with the slope of the waves in cm/s?
