Hey Negrini!
We have a Beneteau 43 currently being commissioned and are very familiar with some of the details (I even visited the factory in South Carolina in February). You can see some of the pictures in our SeaKnots profile.
To answer your questions, the
windlass is
Lewmar (don't know the power), the house batteries are 4Ds (200 Amp each) and the microwave should be easily run with the 3KW
inverter. The
radio is a Sony with remote control and an audio input in the front so you can connect your iPod and the speakers below are by the bulkheads (the ones in the cockpit are under the aft
seats). The shower is protectred by nice acrylic doors. You can see it for yourself if you search for CanDrac on Seaknots.com
And yes, Bennies care about the minor details because the essentials are so reliable that are simply unquestionable! ;-)
