The commission may charge a reasonable fee to each vessel using the port facilities. It may also charge for each copy of any certificate issued by it or its deputies for inspecting hatches, surveying cargoes and the like in regard to vessels using the port facilities in the port area. The master of each vessel shall, however, be furnished free one copy of all surveys upon his vessel or cargo. The commission may, when authorized so to do by a vote of a majority in number and value of the property taxpayers of the district qualified to vote at an election held for the purpose in accordance with law, and for the period of time authorized in said elections, levy annually an ad valorem tax not to exceed two and one-half mills on the dollar on the property subject to taxation situated in the district.

The commission may likewise borrow money for the said purpose from time to time and issue certificates of indebtedness secured by any fees authorized under this section and by any taxes authorized under this section provided that such indebtedness shall in no year exceed the estimated revenues for such year.
