Hi all,
I just purchased a GB42, 1995 from a private party. He went over the systems and operation of the boat but even after that I have a few questions that he wasn't able to answer:
1. When he demonstrated the departure procedure, once shorepower was disconnected, he started the Onan and switched from short to generator. Then he started the main engines for departure. I asked him why the generator was necessary while underway and he couldn't explain. My thinking is that the alternators will keep the batteries charged. Am I wrong to think running the generator while underway is senseless?
2. When on shorepower, are the AC outlets powered directly by the shorepower or still off the inverter? In other words does the shorepower go solely to the battery charger?
Many thanks.....my guess is I'll get some great answers.
