Any vessel desiring a berth at the Port of Gulfport shall, not less than 48 hours prior to the time of docking, make application in writing on the prescribed form through a licensed agent to the Port Authority for a berth assignment specifying the dates and estimated hours of arrival and sailing, and the nature and quantity of cargo, if any, to be handled. Applications for berth assignments are made by agents of the vessel. Requests made by agents acting for the owners, shippers or receivers of the cargo and performance of any service under this tariff constitutes an agreement by said agents, as the case may be, to be held separately bound and ultimately liable for the payment of all or any part of the charges incurred by the vessel and/or its owners or by the cargo and/or its owners, shippers or receivers, as their respective interests may appear. Application for berth assignment or other facility constitutes an agreement between the applicant and the Port Authority that all charges will be promptly paid upon presentation of invoice therefor, and that applicant will comply with all rules and regulations of the Port Authority.
