Marine Event Permits

Depending on where you sail, you may be required by the US Coast Guard to have a Marine Event Permit.   As a rule of thumb, if there is commercial travel or protected species, it is probable that you will need a permit; however US Sailing recommends that you always check with your local Coast Guard.

Applications for a marine permit must be submitted for all marine events which, by their nature, circumstance or location, will introduce extra or unusual hazards to the safety of life on the navigable waterways of the U.S. The requirements for the submission of marine event permit applications can be found in Title 33 or the Code of Federal Regulations, Part 100 (33 CFR 100).

Marine event permit applications must be submitted either electronically or on form CG-4423 to the cognizant Captain of the Port no less than 135 days prior to the event; or 60 days prior for events where the sponsor submitted a permit application in the year immediately preceding if the date, time, and location are essentially the same.

Due to the requirements involved with processing a permit, failure to submit applications within this time may be cause for the permit application to be denied. In addition, failure to submit a permit application can result in termination or cancellation of the event and a civil penalty of up to $32,500.
