25. Whenever the territory of a municipality is bounded on any side by navigable or other waters or by the bank or beaches of such waters, the jurisdiction of the municipality for police purposes shall extend in front of the territory of the municipality to the middle of such waters and to the islands and shoals therein found, if such territory does not already form part of the territory of a municipality erected hereunder or under any other general law or special Act.
If, however, the waters fronting the territory of the municipality be wider than 3 kilometers, such jurisdiction shall not be exercised on more than 1.5 kilometers from the bank or shore.
