Watch these videos if you are doing your BCU 1 star in a kayak
Take a look at each of these YOUTube videos. They take you through all the basic strokes you need to know as part of your BCU 1 star award, if you are in a kayak.
This basic video shows you how to hold a paddle.
Here is one for forward paddling
And the forward sweep stroke
And one you also need to look at reverse sweep stroke (like the one above but opposite direction)
Also reverse padding
And for stern rudder all we could find is someone's holiday video - see how she gets the kayak paddle low and puts the paddle in at the back of the boat and uses it there to turn the boat. She could really get he hands a bit lower.
