It's a Wilderness Systems Ride 115 and I absolutely love it. It's super stable for standing and fishing. I stand and fish in it most of the time now. Actually almost every fish I caught and landed that day while standing. During colder months, I don't do that because I don't want to fall in. It's stable enough that it absolutely won't tip over but that doesn't mean I can't lean too far back while setting the hook and fall out. I've come close a couple times. I sometimes even sit on the edge of the yak, letting my legs hang in the water, and let the wind blow me parallel to the bank while casting.
Head up to Hendersonville and check out HOOK1 (
www.kayakfishinggear.com) and they will take great care of you. That's where I bought mine and there are several members of this forum who are kayak fishermen and bought their yaks from them. They'll even take you to Old Hickory to let you demo a kayak for free. I demoed this one for about 3 hours, fished out of it, and bought it as soon as I got back in the store. The staff are all avid kayak fishermen who know their stuff. They won't pressure you to buy the most expensive model, they'll get you in what fits your needs and budget best. I never once felt pressured.
