I occasionally run a suitcase generator on the bow of the boat when we are at anchor and don't worry in the slightest about fumes and CO poisoning.
The real answer is to be aware of the risk from exhaust fumes and take appropriate precautions to ensure that they don't enter the boat.
I would suggest that the bow isn't the best place for it when at anchor due to the boat most likely lying to the wind, and the CO from the genny being blown across the boat and cockpit. Certainly better to always have the exhaust downwind of your accommodation.
