The problem is that it won't track at all, and the wind'll blow it around like a balloon. It's really more of a pool toy.
Have you considered a float tube? They are made for fishing, smaller and less expensive than the Sea Eagle.
As a reasonably experienced kayak fisherman I can say that I have never paddled a Sea Eagle. I have been on the Charles when two other guys were fishing out of them so I only know from what I saw -- that they had had little to no control in the wind and current on a nice day. God help them if they get caught on a lake when the weather turns bad.
I understand your space limitations and I'm not advising you to not purchase this. But I am trying to help you understand the risks and benefits. If you are only going to be paddling on warm, calm days then this boat is fine.
