Since there was a thread about bringing dogs aboard, I have another question. We are looking at trading up to a 260 or 280 in 6-8 mos mostly to give us the freedom to travel the Tampa, St Pete, Sarasota coast. This would include overnighting in different marinas at times. Our issue is that we would bring our yellow lab with us and I question if it is safe to leave her on the boat if we went out for dinner, shopping, ect for a couple hours at a time. Of course we would most likely have shore power for the ac, but what precautions are needed in case of power failure? Do you leave the hatches open for air? She would be content to just snooze in the cabin, but I worry about CO2 from other boats, heat from power loss, ect? Do others leave their pets on board alone? I have left her on the boat a few times as we have eaten at local resturants, but we were only 20 yards from the boat and she was in sight.
