SUPPLEMENTARY INFORMATION: The Coast Guard will enforce the special

Hydroplane Race from 8 a.m. until 5 p.m., each day, on July 31, 2025 
through August 3, 2025. This action is being taken to provide for the 
safety of life on navigable waterways during this event. The regulation 
for this event, 33 CFR 100.1301(b), specifies the location of the 
regulated area for the Seattle Seafair Unlimited Hydroplane Race which 
encompasses portions of Lake Washington, Seattle, Washington. The 
regulated area is divided into two zones. The zones are separated by a 
line perpendicular from the I-90 Bridge to the northwest corner of the 
East log boom and a line extending from the southeast corner of the 
East log boom to the southeast corner of the hydroplane race-course and 
then to the northerly tip of Ohlers Island in Andrews Bay. The western 
zone is designated Zone I, the eastern zone, Zone II. The Coast Guard 
will maintain a patrol consisting of Coast Guard vessels, assisted by 
Auxiliary Coast Guard vessels in Zone II. The Coast Guard patrol of 
this area is under the direction of the Coast Guard Patrol Commander 
(Patrol Commander). The Patrol Commander is empowered to control the 
movement of vessels on the race-course and in the adjoining waters 
during the periods this regulation is in effect. The Patrol Commander 
may be assisted by other federal, state, and local law enforcement 
agencies.
    Only authorized vessels may be allowed to enter Zone I during the 
hours this regulation is in effect. Vessels in the vicinity of Zone I 
shall maneuver and anchor as directed by Coast Guard Officers or Petty 
Officers.
    During the times in which the regulation is in effect, swimming, 
wading, or otherwise entering the water in Zone I by any person is 
prohibited while hydroplane boats are on the race-course. At other 
times in Zone I, any person entering the water from the shoreline shall 
remain west of the swim line, denoted by buoys, and any person entering 
the water from the log boom shall remain within ten (10) feet of the 
log boom.
    During the times in which the regulation is in effect, any person 
swimming or otherwise entering the water in Zone II shall remain within 
ten (10) feet of a vessel.
    During the times this regulation is in effect, rafting to a log 
boom will be limited to groups of three (3) vessels.
    During the times this regulation is in effect, up to six (6) 
vessels may raft together in Zone II if none of the vessels are secured 
to a log boom.
    During the times this regulation is in effect, only vessels 
authorized by the Patrol Commander, other law enforcement agencies, or 
event sponsors shall be permitted to tow other watercraft of inflatable 
devices.
    Vessels proceeding in either Zone I or Zone II during the hours 
this regulation is in effect shall do so only at speeds which will 
create minimum wake, seven (7) miles per hour or less. This maximum 
speed may be reduced at the discretion of the Patrol Commander.
    Upon completion of the daily racing activities, all vessels leaving 
either Zone I or Zone II shall proceed at speeds of seven (7) miles per 
hour or less. The maximum speed may be reduced at the discretion of the 
Patrol Commander.
    A succession of sharp, short signals by whistle or horn from 
vessels controlling the areas under the direction of the Patrol 
Commander shall serve as signal to stop. Vessels signaled shall stop 
and shall comply with lawful orders of the patrol vessel; failure to do 
so may result in expulsion from the area, citation for failure to 
comply, or both.
    The Coast Guard may be assisted by other federal, state, and local 
law enforcement agencies, as well as official Seafair event craft.
    In addition to this notification of enforcement in the Federal 
Register, the Coast Guard plans to provide notification of this 
enforcement period via marine information broadcasts, and Local Notice 
to Mariners.
