Kayak
I just started boating a few years ago, and I've currently got a Big EZ (by Wavesport). I'm around 150 lbs and 6' and it's worked well for me so far. It's worked great as a river runner (I've done up to class IV+ in it), and it's also pretty decent for surfing and playing in holes. Although it's a little hard for me to throw ends, it would probably work fine for you since you're a little bigger than I am. Plus, since they've been around for a few years, you might be able to find a good deal on a used one. Good luck!
