Sail on Sea Kayak

After making my new rig for my Capella Sea kayak, I set everything up in the garden to try it out in a light breeze.
The mast needed supported with bunji straps to take the strain fore and aft; also I noticed a block needed to be fixed in the center of the hull so the paddle will not hit the sheet.
The poly tarp sail is of a Bermudan style, and may need battens to help it have maximum efficiency.
In general, it worked well, probably not good to windward, but on a run, I think it will be enough to rest the arms and use the oar as a rudder. I will be using ‘sponsons’ either side of the cockpit for stability, and I may even fix a lee-board for upwind use.
