Re: generator on a boat
If you are underway and the genny is downwind at all times, you have very little to worry about. Don't do anything boneheaded like put it in the engine room (no, the blower won't evacuate the CO) or put it in the cockpit or cabin. Strap it to the swimstep, keep the boat moving and all will be well. Good luck with your parade of lights, it sounds great!<br /><br />One last alternative to consider. Use strings of LED lights and a cheap 50 or 75W inverter plugged into a 12V socket. LED xmas lights were pricey 2 years ago, now they're almost giveaways.
