The Great Chesapeake Bay Swim, Inc. will sponsor the “Great Chesapeake Bay Swim” and the “Chesapeake Challenge One Mile Swim” on the waters of the Chesapeake Bay between and adjacent to the spans of the William P. Lane Jr. Memorial Bridge. Approximately 650 swimmers will start Great Chesapeake Bay Swim from Sandy Point State Park and swim between the spans of the William P. Lane Jr. Memorial Bridge to the Eastern Shore. Approximately 400 swimmers will start the Chesapeake Challenge One Mile Swim following a triangular shaped course beginning and ending at Hemingway's restaurant on the Eastern Shore adjacent to the William P. Lane Jr. Memorial Bridge. A large fleet of support vessels will be accompanying the swimmers. Therefore, to ensure the safety of participants and support vessels, 33 CFR 100.507 will be enforced for the duration of the event.

Vessel traffic will be allowed to transit the regulated area as the swim progresses, when the Patrol Commander determines it is safe to do so. 

In addition to this notice, the maritime community will be provided extensive advance notification via the Local Notice to Mariners and marine information broadcasts so mariners can adjust their plans accordingly.
