Agree with Catmaster, you'll love yourself, the boat, and fishing more if you save up for a nice kayak. I loved fishing out of a canoe though, and they're cheaper. Used to fish every weekend in the Gulf in a canoe, held the GF, cooler, and gear no problem.
Ever thought about getting a wall mount system catmaster to free up some room?
At not to be a worry-monger, but I've heard that it's not good for the hull to store kayaks hull-down. Heard it can warp the hull and mess with the tracking of the boat, and it's better to store them upside-down or on their side, but hull-down on some open cell foam is fine too. Out of paranoia, I store mine (tarpon 140) upside-down on some sawhorses
