Some of the best memories are of days spent on the water.

The Neptunus 650F is designed and built to meet the CE Category A – Ocean standard, delivering exceptional performance, seakeeping ability, and ease of handling. She cruises comfortably at 26 knots, and handles the seas with ease.

Neptunus Yachts is proud to introduce an exciting new layout for the Neptunus 650F. This is our most open, spacious and bright interior yet. The fully-equipped galley aft has a centre island, that will quickly become your favorite space for relaxing. The entertainment centre includes an automatic espresso maker for morning coffee, and a beverage fridge for afternoon or sunset drinks. Forward are an inviting salon and a dinette which offers 360 degree views.
