It is shown that for fully developed random sea, if sea state is below certain critical value, ship will always tend to turn head to waves, but if above larger critical value, ship will always tend to turn beam to waves; for sea states between these values direction that ship will tend to turn can be determined from graph presented; numerical evaluation discloses that, for typical values of pitch natural frequency of full-scale ship, lower critical value corresponds roughly to upper sea state 5; as most sea states are below 6, ship will tend to head into waves.
