I’ve taken the SKABC Currents course as well as the Chilliwack Centre for Excellence 6 session intro to whitewater. I did CCE’s first and then Currents the following year, but looking back I’d have done it in reverse. Currents teaches the techniques in friendlier waters in a sea kayak context.
Coming from CCE, which was super fun but a lot rougher, I was quite nervous going into Currents because I was expecting much rougher waters, but with my 17.5ft sea barge instead of a nimble little whitewater boat. I think it made me more cautious and tense than I needed to be which led me to take fewer risks and gain a little less experience. I think doing Currents first and then CCE would be a better skill progression both mentally and physically.
Highly recommend both courses either way.
