Thanks for the feedback, I think I will try https://www.onlineseakayaking.com/ for $12/month, the production values of their samples is quite good. I have a good paddle stroke, used to do 25mi flatwater paddles before kid, it's more the surf, rough seas, moving water techniques and rough water rescues I need to work on, which seems to be the forte of those videos. I just upgraded my old Dagger Magellan to an Eddyline Fathom, looking forward to getting back into it.
Are there ever pond sessions nearer the Chelmsford area?
Thanks!
Tim
