A boat is said to be turtling or to turn turtle when it is fully inverted.[1][2] The name stems from the appearance of the upside-down boat, similar to the carapace (top shell) of a sea turtle.[3][A][B] The term can be applied to any vessel; turning turtle is less frequent but more dangerous on ships than on smaller boats.[C][4] It is rarer but more hazardous for multihulls than for monohulls, because multihulls are harder to flip in both directions. Measures can be taken to prevent a capsize (where the boat is knocked over on its beam-ends but not yet inverted) from becoming a turtle (with bottom up).[5][6][7][8]
