I believe that Sail Magazine, in the last few months published the number of boating fatalities in the US in one year. Sailboats , around 28. Power boats , in the hundreds
According to NOAA, in 1998, of the 16,824,000 boats in use, only 1,669,000 were sailboats. So when you say "in the hundreds" do you mean more or less than 252? If it's less than 252, then per boat, sailboats are associated with more deaths than powerboats.
I'm not saying this is the case; in fact I doubt that it is, but the number "28" is meaningless by itself, and comparing sailboat-deaths to powerboat-deaths is meaningless if we don't have any other information about the populations (sailboats and powerboats) themselves.
On a good boat in mid ocean is probably one of the safest places on the planet .
Perhaps, unless you happen to be sinking, or a terrible sailor, or in need of medical attention, or in a storm.
Being in a stationary car on a rarely used road far away from any population centers is probably just as safe. Does that mean that driving is just as safe as sailing?
