Fished is a couple times in kayak tourneys. The stock it with rainbows and brown trout, both of which i have caught from my yak. I have also caught Large mouth and Small Mouth bass, but nothing of size. If you intend to target trout, trolling the middle area where it drops off is often a good way to start.
PS.. My offer for the Quabbin trip is still open if you want to save some $$.
