Your sailing profile
You often make long trips and despite the luxury onboard facilities do not want to have to constantly depend on shore power. Ease and comfort are important and you like to have the same conveniences as you do at home while also being able to use a winch when moored in the harbour. Your comprehensive navigation system is spread across various indoors and outdoors screens, and you have a hydraulic, remote controlled passerelle. You also expect the components of the electric system to be seamlessly compatible with each other and provide a carefree system performance. Wherever you are, you also need complete security of service should there be a malfunction.

The Basics
- You charge your batteries with heavy alternators on the main engine while sailing so seldom need shore power.
- You use the generator for recharging while you are moored or anchored without having shore power available.
- You do not want to have to think about what to use or when. Everything at the same time is best.
- Your navigation station includes GPS, plotters, speedometer and depth gauge, and there is an onboard marine telephone.
- Your ship has several pumps for water, shower, toilet and bilges.
- You require optimum ease of operation; not only centrally located but also next to your bed or in the engine room.
