System features manual control of engines and thrusters with single joystick as well as automatic position keeping.
Despite having same functionality and operation philosophy, NavJP is not a full scale dynamic positioning system. It is designed to be operated by skipper offering much more simple control comparing to DP.

We delivered our first system to Christensen Shipyard in 2008 for 50m custom yacht Remember When, equipped with a traditional propulsion consisting of main fixed pitch propellers, rudders, bow tunnel and additional stern azimuth thruster.

Please use menu on the right to get more details on this product.


Since than we help to get the control over the intricate propulsion back to the captain on board of yachts and shadow vessels from 24m and up to 100m length, mono and multihulls. We have experience with controlled and fixed pitch propellers, direct diesel drive, hybrid and diesel-electric propulsion, tunnel and azimuth thrusters, water and pump jets.

«The Product: The NAVIS AP and JP system has a very user friendly appearance, its user interface is easy to learn, and the product operation and handling of the vessel is of outstanding quality. 

The Operation: The Autopilot enables operation in a number of modes of great usefulness for the daily operation of the ship.  Being harbor maneuvers, sailing in narrow channels, anchoring in areas with strong wind or current, it operates flawlessly.  Operations in JP modes are extraordinary and very convincing.

The Team: The NAVIS installation and service team is among the most efficient and the fastest handling we have experienced.  User interaction is friendly and expedient. Response time is very fast».
