# SUPPLEMENTARY INFORMATION:

The Coast Guard will enforce Seattle Seafair Unlimited Hydroplane Race special local regulations in 33 CFR 100.1301 from 8 a.m. on July 31, 2018, through 8 p.m. on August 6, 2018.

Under the provisions of 33 CFR 100.1301, the Coast Guard will restrict general navigation in the following area: All waters of Lake Washington bounded by the Interstate 90 (Mercer Island/Lacey V. Murrow) Bridge, the western shore of Lake Washington, and the east/west line drawn tangent to Bailey Peninsula and along the shoreline of Mercer Island.

The regulated area has been 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. (Refer to NOAA Chart 18447).

The Coast Guard will maintain a patrol consisting of Coast Guard vessels, assisted by Coast Guard Auxiliary vessels, in Zone II. The Coast Guard patrol of this area is under the direction of the Coast Guard Patrol Commander (the “Patrol Commander”). The Patrol Commander is empowered to control the movement of vessels on the racecourse and in the adjoining waters during the periods this regulation is subject to enforcement. The Patrol Commander may be assisted by other federal, state and local law enforcement agencies.

Only vessels authorized by the Patrol Commander 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 the Patrol Commander.

During the times in which the regulation is subject to enforcement, the following rules shall apply:

(1) Swimming, wading, or otherwise entering the water in Zone I by any person is prohibited while hydroplane boats are on the racecourse. 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 10 feet of the log boom.

(2) Any person swimming or otherwise entering the water in Zone II shall remain within 10 feet of a vessel.

(3) Rafting to a log boom will be limited to groups of three vessels.

(4) Up to six vessels may raft together in Zone II if none of the vessels are secured to a log boom. Only vessels authorized by the Patrol Commander, other law enforcement agencies or event sponsors shall be permitted to tow other watercraft or inflatable devices.

(5) 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, 7 miles per hour or less. This maximum speed may be reduced at the discretion of the Patrol Commander.

(6) Upon completion of the daily racing activities, all vessels leaving either Zone I or Zone II shall proceed at speeds of 7 miles per hour or less. The maximum speed may be reduced at the discretion of the Patrol Commander.

(7) A succession of sharp, short signals by whistle or horn from vessels patrolling the areas under the direction of the Patrol Commander shall serve as signal to stop. Vessels signaled shall stop and shall comply with the orders of the patrol vessel; failure to do so may result in expulsion from the area, citation for failure to comply, or both.

The Captain of the Port may be assisted by other federal, state and local law enforcement agencies in enforcing this regulation.

This notice of enforcement is issued under authority of 33 CFR 100.1301 and 5 U.S.C. 552(a). If the Captain of the Port determines that the regulated area need not be enforced for the full duration stated in this notice of enforcement, he or she may use a Broadcast Notice to Mariners to grant general permission to enter the regulated area.

Dated: June 19, 2018.

M.M. Balding,

Captain, U.S. Coast Guard, Acting Captain of the Port, Puget Sound.
