    All the vessel surveys I have seen here for diesels, insist on co detection every seating or sleeping area.

    Good precaution Although all these years I ve never had one sound off. For example we have one just inside the transom door on the boat i run and sometimes we have both 27.5 Kw gens running in light or zero wind with the exhaust on each side of the transom, door open. Never got an alarm

    One thing to keep in mind is that CO builds up gradually in the body and doesn’t go away quickly. If someone is on a board very close to the boat for 30’, takes a break for and goes back on the board, the meter hasn’t reset. The CO level is still there ready to build up some more in the body. Repeat a few times and it is very possible that at the end of the day CO at built to lethal levels

    I have seen many wakeboard, ski boats etc pulling people VERY close to the stern right on the wake. Throw into the mix an older gas engines run on a heavy load to generate max wake and it s a recipe for disaster.

    This is just a completely freak accident. It's an open ski boat with low gunnels. The breeze must've been almost exactly the same speed and direction the boat was going in to cause this. It's very unfortunate.

    This. It could have been ultimately not riding around in the boat at idle, it could have been some swimming activities right around the swim platform for too long etc,,,, reading up on how it builds up in your bodies is an interesting read.

    Although it is more accelerated while diving under pressure (water depth. additional atmospheres), CO builds up in the blood and needs a long while to gas off. If the child was continuously hanging around the stern during the day, the CO build up would get to him.
    Again a shame.

    There were warning signs, all the young ones complained.
    Senseless and stupid deaths have to be accounted for one day.

    As stupid as all the people dying after every storm because of their gas gensets.

    The reason multiple exposures to CO lead to increasing levels has to do with the affinity of our oxygen carrying hemoglobin in our blood for CO is about 200-250 times it’s affinity for binding oxygen. It is more tightly bound to the hemoglobin and does not leave the hemoglobin very rapidly. It is more rapidly displaced by 100% oxygen which is a major treatment for CO poisoning as the higher level of oxygen effectively competes with the CO for the hemoglobin binding sites.
