The Negon is an autonomous polygonal floating mooring system for pleasure yachts, capable of providing modern mooring services.

"Niigon" (in Greek: Νηίγων) is a vessel with multiple angles. It derives from the ancient Greek word of «ναῦς» (in dative form: «τῇ νηί») and the geometrical term for polygons with n sides or angles, n-gonon.

Its purpose is to resolve the problems created during open-sea anchorage, since it can be used in suitable areas. It can be reliably applied to the operational space between open-sea anchoring, mooring on a buoy, and anchoring in a marina, by bridging the gap between them and combining the positive features of all three methods, without the necessity for port or terrestrial structures.
