EXAMPLES

Complete comfort on the water

Sailing profile

You normally go sailing for a weekend or midweek, sometimes anchored without access

to shore power so you need enough power to cruise for two days. You also desire a

range of comforts onboard, including a large refrigerator, microwave/oven combination

and high-end coffee/espresso machine. Internet and email facilities are on your wish

list as is (partial) navigation using your laptop, a good sound system and occasionally

watching your favourite TV show.
