+1 for what Philstar says, having been a boatie all my life then taking up sea kayaking in the nineties, the more I did the more respect I had for Caffyn and one or two others, surfing is definitely to be recommended in a fully loaded condition for concentrating the mind.Often the ex was convinced that I was trying to drown her, on reflection would have been cheaper.
Its a great healthy sport suitable for anyone who has a real respect for the sea.
