(1) Any agency or political subdivision of this state may make application to the commission for special rules and regulations with reference to the operation, equipment or safety of vessels on any waters of this state within its territorial limits or authorized jurisdiction and shall set forth therein the reasons which make special rules or regulations necessary or appropriate. The commission is hereby authorized, after notice and a public hearing as provided in Section 59-21-117, to make special rules and regulations with reference to the operation, equipment or safety of vessels or motorboats on any waters of the state.

(2) The several counties and municipalities bordering the Mississippi Sound or the other coastal or tidal waters of this state are authorized and empowered to adopt ordinances setting out special rules and regulations with reference to the operation, equipment, or safety of vessels or motorboats on the Mississippi Sound or the other coastal or tidal waters of the state within their territorial limits, and shall set forth therein the reasons which make special rules and regulations necessary or appropriate. No ordinance shall conflict with the provisions of this chapter or with the regulations of any federal agency having jurisdiction over those waters. Notice shall be given of the proposed ordinance and a hearing shall be held thereon before the Commission on Marine Resources as provided in Section 59-21-117, and as a condition precedent, the Commission on Marine Resources shall recommend the adoption of the ordinance.

(3) It is the intent of this chapter that uniform regulations of general application to all the waters of this state shall be adopted and promulgated wherever practicable, and any special regulation or local ordinance, as authorized herein, shall be limited to the exigencies of local conditions which cannot be corrected by a regulation generally applicable to all the waters of the state.
