(1) Pilots shall observe rest period requirements as set out in RCW 88.16.103 as now or hereafter amended. Pilots shall have a mandatory rest period of at least ten hours with an opportunity for eight hours of uninterrupted sleep after completion of an assignment; excluding multiple assignments within a harbor area, provided the combined total duration of assignment time does not exceed thirteen hours.

(2) An assignment is a billable pilotage service, including cancellations and ship movements, regardless of duration

(3) An assignment begins at call time and ends at check-in time and includes preparation time and travel time to and from the ship in addition to bridge time. Call time allows one to two hours of preparation before the start of travel time to the ship. Check-in time occurs when travel time from the ship is completed. In the Puget Sound Pilotage district travel times are documented in the Puget Sound pilots operating rules and may be reviewed by the board from time to time.

(4) When there are multiple assignments within a harbor area (multiple harbor shifts), call time is before the first harbor shift and check-in time occurs when the travel time has been completed after the final harbor shift. Harbor area geographic definitions outlined by the utilities and transportation commission are used to distinguish harbor shifts from other ship moves.

(5) Pilots shall not complete more than three consecutive night assignments, a night assignment being one in which any part occurs between 0100 and 0459 hours. After three consecutive night assignments, pilots shall have a mandatory rest period of at least twelve hours, including at least one period between 2000 and 0800 hours.
