Foule-Water.
When a ship (under saile) comes into shallow wa∣ter, so that she raises the mud or sand with her way, (which she may doe, though she doe not touch the ground, but come very neere it) we say she makes foule-water. Note that a ship in Showle-water, when she sailes with her Keele neere the ground, cannot feele her Helme, as well as in deep water: The reason is, for that neere the ground, the water hath not that weight and force as it hath when it is deep: and also by reason of an Eddy, which is made betwixt the ground and the bottom of the ship, being so neere together, the water cannot come so swift to the Rudder, as it doth in deeper-waters: And note also, that the swifter the water comes to the Rudder, the better the ship doth steere, or feele her Helme.
