Sail on Sea Kayak

I got round to fixing the existing sail onto the rig of the Capella sea kayak. I found the sail too small and I will make a bigger one, and use it with sponsons to give that extra stability, but I do not intend to use the sail in high winds, the sail is an aid to paddling only, not a substitute. I will be trying out out on the Solway quite soon and getting to channels and rivers that I can not get to by boat. The rigidity is good, the bindings are tight and I believe it is secured tightly.
