Why is this even being discussed? I know of many large cruisers that have 7.2kWh (600Ah x 12V) or larger house banks and nobody is suggesting that these batteries represent a clear and present danger. In any case, lead-acid batteies are obviously way too dangerous to put in a boat, so Lithiums are the only safe choice in powering an electric boat (just kidding, in case anyone thinks my last statement was serious)
Back when seatbelts were first being mandated, some people were worried that a seat belt might increase in-car drownings when a car went into a lake or canal. While theoretically possible, this has turned out to not be an issue.
In 20 years of coastal and off-shore sailing, I have never sunk any of my boats (well I did turtle a sabot, but I was trying to). I would think that you should be more concerned about what a lightning strike is going to cost you. (oops, this is going to start another thread that has no practical solution)
