Green Cruising

JONATHAN’s energy system was designed to serve two purposes: Firstly, to produce environmentally friendly electricity by harnessing sun and wind energy; secondly, the objective was to use, and save, energy wisely, without losing comfort. 2.5 KW solar panels provide electricity on JONATHAN under standard conditions. The diesel generator is used only as a back-up. When the diesel engines are in operation, four large alternators feed the ship’s batteries.

To save electricity, JONATHAN is equipped with energy-saving, bright LED lamps. The navigation lights need as little as one tenth of the conventional filament lights – with a higher light output. The modern radar system can be switched electronically to energy-saving mode, without loss of security, thus reducing the power consumption by 70 percent. The freezers are well insulated and keep food and drinks cool with the lowest possible power consumption. We will never run out of ice for wonderful Caribbean cocktails.
