Here's the new (to me) pontoon I'll be buying later this month...it's built on X-Stream ten foot pontoons, with a Skookum Steelheader frame. It's previous owner, besides buying a very quality frame and pontoons, did a lot of custom work on it, as you can see. I've got a few more modifications that I'll be making to it, as well.
I rarely fish lakes, but I'll use it when I do, at least if I have to paddle very far...I've got a couple U-boats and float tubes for that kind of fishing. This boat is rated for up Class IV+ rapids, will be very nice on the rivers I fish (Sauk, Sol Duc, etc.).
Finally, I think it will just fit in the back of my van without being taken down...but even if it doesn't, I can either put it on the 13 foot rack on the roof, or take the 'toons off and stick them and the frame in the van, if I'm travelling more than an hour or so.
