I saw that boat for sale in a community news letter. You would be best served to just pony up the cash and buy a decent paddle. There are two things I will not go cheap on in kayak fishing, a good seat and a paddle. Bending branch makes an Angler Slice paddle that retails for about $125. Just buy it. It comes in 240 and 230 cm. Don't buy a cheap paddle you will regret it.
Check out the Backpacker in Br or Lafayette, or pack and paddle. They both carry this paddle.
It also makes a good push pole.
