At other times, recreational vessels may be allowed to lock through with commercial craft at the discretion of the lockmaster.
Lockages outside the scheduled times will be considered for flotillas or other organized events sponsored by yacht clubs, marinas and other groups, provided 24-hour advance arrangements are made with the appropriate location.
Everyone in the vessel must be wearing a personal floatation device throughout the duration of the lockage. All vessel owners and operators lock through at their own risk and must comply with the Corps’ safe-lockage policy.
