I had a Do It Now when I became interested in whitewater paddling, and before I learned to roll. It's a great boat for class II with some class III downriver runs. It would probably surf with the right standing wave, and the right paddler, but, I never made that combo. The DIN paddles in a straight line better than some whitewater boats of similar length, yet still spins around easily with not much of a paddle stroke. I found getting back on board after a spill to be quick and easy, with handles apparently positioned for that purpose.
It has thigh straps, which are important to handling in whitewater. This also allowed some other paddlers to roll my boat, when they were trying it out of curiosity. The sitting position is very good, encouraging upright or slightly forward posture. There's no provision for a backband or seat, but, I never missed either item. In fact, the only potential comfort issue was that my outside ankle area touched the footbrace railing. I thought this would bother me, but, I rarely noticed it. The foot braces themselves are oversized, and very comfortable.
There's a large screw hatch that allows access to the inside hull, where you can stash extra water, sun screen, lunch, etc. Of course, you have to keep all this stuff from getting loose and out of reach. I tied a piece of rope around one of the scupper tubes under the seat, and clipped a drybag or mesh bag to the rope. The hatch on my boat was not water tight, due to imperfect installation. It never bothered me enough to re-install the hatch properly. I've seen the boat a few times since selling it. The hull is showing some mild oil-canning. It can't get too bad, due to the structure of the scupper tubes. But, I can see potential, depending on use/abuse, for wear to occur around the scupper holes possibly leading to leaks.
