19.16.280 Speed of Vessels.

A.  All vessels and other watercraft during foggy or smoky weather, mist, falling snow, heavy rain, or other obscuring weather, shall proceed at a moderate speed, having due regard to the existing conditions and circumstances.

B.  All vessels and watercraft must keep clear of seaplanes while they are taking off or landing within any district set aside for that purpose.

C.  All motorboats shall proceed with caution while in the harbor and not try out for speed if other small boats are in the vicinity in numbers, except during permitted regattas, races, or demonstrations.

D.  All vessels when passing dredges, drydocks, vessels under repair, diving, or grappling operations, or other submarine work, shall slow down to not more than 6 statute miles per hour.  While passing over the mooring lines of any such activity, the propellers or other propelling machinery shall be stopped; and if their draft permits, the vessel shall keep on the outside of the buoys marking the ends of the mooring lines of floating plant that may be working within the channel area.

E.  No vessel shall be operated in the port at any speed whereby any damage may be done to the property of another or life may be endangered thereby by the suction of waves, swells, or wake caused by such speed.
