Minimum requirements.

A private seaplane base will be granted a license when it has shown that it has met the minimum requirements of this part.

Subp. 3.


In case the body of water to be used for landing and taking off is under the jurisdiction of any federal, state, municipal port, or other authority, the operations on such body of water shall be in conformity with the marine traffic rules and regulations of such authority, to the extent such rules and regulations do not interfere with the safe operation of aircraft.

Subp. 4.

The body of water shall be of sufficient length, width, and depth to permit safe operation by the aircraft intended to use it. The approaches to the landing area shall be sufficiently clear of obstructions to permit a 20:1 glide angle to the nearest point of the usable landing area, provided that if any structure on the land is located within 300 feet of the centerline of the approach path, such glide angle shall be computed so as to provide a clearance of at least 100 feet above such structure.
