The U.S. Coast Guard is implementing a 100-yard security zone to include passenger vessels operating in the Strait of Juan de Fuca and Puget Sound. This includes, but is not limited to, the Washington State Ferries. Post-Sept. 11 security zones prohibited boaters from approaching within 100 yards of U.S. military vessels and tankers; and operate at minimum speeds within 500 yards. The Coast Guard is now also imposing security zones in the vicinity of all passenger vessels more than 100 feet in length. “The U.S. Coast Guard is taking appropriate security measures consistent with the change in the Homeland Security Advisory System level,” said Capt. Danny Ellis, Commanding Officer, Marine Safety Office Puget Sound.
