In Australia (80+% of population living on the coastline) it's common to see schools providing the "Bronze Medallion" (http://www.royallifesaving.com.au/training/bronze-medallion) as a recommended course for students.
I'm not sure how applicable this would be to the USA, but I can't see that it would hurt (it also provides basic first-aid training and CPR practice which have saved some lives as an incidental side effect).
