Do you ever think about how you’d recover some who had had a heart attack? Or someone who has fallen critically unwell? Or someone who’s just blood knackered after a hard paddle and who can’t make it back safe?
If you paddle as part of an accredited SUP or paddleboard club, then you’ll almost certainly know all this already, so sorry for wasting your time. If you don’t, ask your club why not! But for everyone else who’s learning as they go along, these videos are a great safety aid. You just need to go out an practice them now.
