On the comments about drilling stove
exhausts & adding sheet metal screws to them. By doing so I would think that you're introducing leaks
into what (ideally) would be an airtight system, which could result in toxic exhaust
gases in the boat's cabin
. And since the air turn over rate inside of a boat
isn't that high, this might be problematic, non? As opposed to doing so in a home installation
, where the huge volume of air inside of the building as compared to a boat
might mitigate this, slightly. Though I'm still not in love with the idea, given how some homes are damn near airtight.
Why add CO & other non-breathable gases into your living space?
