I put this in the for sale section, as if you take the RNLI up on the free DVD offer you should make a donation.
Hopefully never need their help but good to know they exist
http://www.rnli.org.uk/how_to_support_us/give_money/give_regularly/seriousfun/seriousfun-trailerThe DVD is NOT ABOUT HOVERCRAFT but I guess most water safety tips apply to all modes of water going craft. Quote from their website "
The DVD is packed with great tips from top trainers and sports experts for staying safe on the water, whether you’re into sailing, power boating, windsurfing, kite surfing, diving, water skiing, angling, or canoeing. Whatever your passion, getting out on the water is about having Serious Fun!"
