Re: Portable Genny

It depends on your charging vs power draw differential after considering alternatives.

On our boat with electric refrigeration, soon to be installed 12V watermaker and lots of electrical gadgets and limited space for extensive solar panels and where we avoid using the motor as much as possible we run a Honda 1000 genset to a 50 amp charger for four hours every 3 or 4 days or so to keep the batteries topped up. We rarely use any AC powered equipment so the genset is essentially for charging purposes only. And. if you really do need one, buy the Honda or Yamaha. Most cheap copies are unreliable and NOISY. Noise levels double with every 3 dB increase, so keep that in mind when comparing specs. Our little Honda cannot be heard more than 10 metres from the boat in a breeze and we only ever run it between mid morning and mid afternoon.

As for Darwining oneself off using a portable genset on a boat I'd have to say that if one was that stupid, they'd most likely have Darwin'd themselves off long before being in a position to buy and own a boat in the first place. Not saying it doesn't happen, but I'd guess no more so than people blowing themselves up with gas appliances on board. It doesn't need much common sense to place the generator in a location that eliminates CO poisoning risk to the boat's occupants. If you're planning to run your genset overnight, however, do not run a portable unit.
