Keep us all informed about establishing a National Center for Cold Water Safety. I'm sure many of the group here would be willing to help in at least getting the word out as your program develops.
I don't know if you've worked with BoatUS or not. They have had grant money for projects like this in the past and are certainly involved with safety issues regarding recreational boating. They have an insurance program and a vessel assist program already well in place and are now making loaner children's PFDs available at marinas across the country. They might be a good partner in your project. I have a contact with them if you'd like it.
