We had this our freshman year of high school (NYC suburb, USA). Perhaps I'm biased from growing up in a coastal town where swimming was a very popular competitive sport and lots of people had boats, but teaching kids in middle or high school is WAY too late IMO, this stuff needs to be taught at a much younger age - like 4-5 years of age.
