The Basics

An (electric) motor capacity of 7.5 kW gives a sailing time of around two hours at an average speed of seven knots. At a speed of five knots your cruising time is four hours.
The maximum AC capacity is 2000 Watt for the microwave/oven; however, you will only use this for a relatively short period of time.
Your navigation station includes GPS, plotter, wind meter, speedometer and depth gauge
You require optimum ease of operation; centrally located.
