Re: Running the Genny at night?
Fun story about carbon monoxide detectors, if you check the detectors ratings they almost always alarm much higher than the limits set by osha, I have no idea why, I stopped trusting those things years ago. You can look up the osha limits online for fun.

Re: Running the Genny at night?
The industry standard for CO alarm points is 35 ppm.......now I believe many of these marine units are using time weighted average alarms because of all the nuisance alarms....this could be what you are referring to.
FWIW.....The above is just my opinion.

Re: Running the Genny at night?
Between the 3 CO detectors that are hard wired and two portable ones I keep next to the beds , I’m confident enough that if there is a CO issue , one of them is alarming and they are loud! I have also trained my kids to go sit on the Aft Deck or Dock , if they ever hear an alarm , fire or CO. We live in North GA , so sleeping on the boat without AC is impossible. For tie ups, I never open any windows, everything is sealed up and closed. We just did a 14 boat tie up this weekend and everyone ran their generator. 90F outside and stagnant as hell. We all operate the same way. Windows closed up and AC on 68F!

Re: Running the Genny at night?
I just pulled up one that states it has an alarm point of 400ppm 4-15 minutes, a safe-t-alert 65 series, guess I was only saying I am pretty skeptical that these sensors would wake me up in time is all.

Re: Running the Genny at night?
Yea,.... in the hot, humid climate situations you really are caught between a rock and a hard place. It would be worrisome for sure. When I said industry standard, perhaps I should have said industrial standards for alarm points.
Knowledge is the best help for safe operation in these situations....IMO....

Re: Running the Genny at night?
It is unsafe and ruins the peacefulness of being on the water overnight for other boaters in the area, in my opinion.

Re: Running the Genny at night?
I agree it's not safe to run one when everyone's asleep. But, I will admit that I have done so on very rare occasion. My genset is, however, located outside the cabin and under the cockpit, so its not like some where it's located under the salon. Also, I double checked my CO2 monitors, and I stayed awake while the admiral slept. Being in the south it was just too hot and humid a night and you know, "Happy Wife, Happy Life!", loss of sleep was a small price to pay to ensure safety.
