A. No watercraft which has in tow or is otherwise assisting a person on water skis, aquaplane, surfboard, innertube, or similar contrivances, shall be operated unless such watercraft is occupied by at least two persons, one who is at least 16 years of age who shall be the operator, and one who is at least eight years of age who shall be an observer or ski tender; provided, that this prohibition shall not apply to watercraft used in duly authorized ski tournaments.

B. No person shall ride or manipulate any water skis, aquaplane, surfboard, innertube, or similar contrivance while in tow or being assisted by a watercraft when such person is under the influence of intoxicating liquor or drugs to a degree which renders the person incapable of safely riding or manipulating such a contrivance.

C. Except on safe takeoffs, watercraft with persons under tow on water skis, aquaplane, surfboard, innertube, or a similar contrivance must keep 300 feet or more from the dock, float, or shoreline. A takeoff will not be considered safe unless the person under tow is heading away from the shore and the takeoff can be accomplished without any risk to swimmers or watercraft. The person under tow, but not the watercraft, may come within 150 feet of the shoreline when in the process of landing; provided, that the return to the shore must be at an angle of 45 degrees or less to the shoreline.

D. No watercraft shall follow behind a skier closer than 300 feet, nor cross the towing boat bow by less than 300 feet, nor alongside a skier closer than 100 feet.

E. Any person on water skis, aquaplane, surfboard, innertube, or similar contrivance shall wear about his body a Type I, II, or III personal flotation device as defined in BMC 12.12.030(C), regarding lifesaving equipment.

F. Any person on water skis, aquaplane, surfboard, innertube, or similar contrivance shall conduct himself upon the same in a careful and prudent manner and shall remain at all times at least 100 feet from other persons and from the property of others.

G. No watercraft shall have in tow or shall otherwise assist a person on water skis, aquaplane, surfboard, innertube, or a similar contrivance from sunset to sunrise; provided, that this subsection shall not apply to watercraft engaged in duly authorized water ski competitions or expositions.

H. All boats towing skiers shall go in a counter-clockwise pattern. [Ord. 9681 § 1, 1987; Ord. 8655 § 3(I), 1978].
