(1) Upon the effective date of this paragraph and thereafter: All vessels shall pay eight dollars and eighty-six cents per pilotage unit; from January first, two thousand eighteen until January first, two thousand nineteen all vessels shall pay eight dollars and ninety-five cents per pilotage unit; from January first, two thousand nineteen until January first, two thousand twenty, all vessels shall pay nine dollars and four cents per pilotage unit; from January first, two thousand twenty until January first, two thousand twenty-one all vessels shall pay nine dollars and twenty-two cents per pilotage unit; from January first, two thousand twenty-one until January first, two thousand twenty-two all vessels shall pay nine dollars and forty cents per pilotage unit; on and after January first, two thousand twenty-two all vessels shall pay nine dollars and sixty-eight cents per pilotage unit.

(2) A minimum charge calculated on two hundred pilotage units shall apply to vessels of less than two hundred units of measurement. A maximum charge calculated on five hundred pilotage units shall apply to vessels of more than five hundred units of measurement.

(3) Pilotage units, as used in this subdivision, shall be determined by multiplying the overall length of the vessel by the extreme breadth by the depth to the uppermost continuous deck and dividing the total by ten thousand, as expressed in the following formula: Overall length X extreme breadth X depth ________________________________________________ 10,000 equals pilotage units

(4) After entering Long Island Sound or Block Island Sound or before departing therefrom, all vessels piloted for less than twenty-five miles shall pay a transporting charge equal to two-thirds of the statutory rate for registered vessels.

(5) A pilot detained on board a vessel at anchor or detained on board a vessel at berth for more than two hours shall be paid at the rate of twenty-five dollars per hour or fraction thereof.

(6) A pilot carried off on board a vessel by reason of bad weather or any other cause shall be paid two hundred dollars per day during the time of his detention. He shall also be awarded first class return transportation at the earliest possible time.

(c) Definitions. "Overall length" is the distance between the forward and after extremities of the vessel. "Extreme breadth" is the maximum breadth to the outside of the shell plating of the vessel. "Depth" is the vertical distance at amidships from the top of the keel plate to the uppermost continuous deck, fore and aft, and which extends to the sides of the vessel. The continuity of a deck shall not be considered to be affected by the existence of openings, including but not limited to tonnage openings, engine spaces, or a step in the deck. All measurements shall be in feet and inches (U.S.). The board of commissioners of pilots shall be the sole arbiter with respect to a question concerning these definitions. The decision by the board shall be final.

(d) The measurements of overall length, extreme breadth, and depth as previously defined, shall be made available to the pilot by the master or his agent for the computation of pilotage fees. Failure to provide the measurements so required shall subject the vessel to the maximum pilotage charge. 5. The board of commissioners of pilots is hereby authorized to execute an agreement with the appropriate state pilotage authority of any state for establishment of a rotation system for the assignment of pilots for the conduct of vessels in the ports and waters of the state, including the waters of Long Island Sound.
