As in I.K.'s you have to attack large waves to penetrate with momentum. Very easy to reboard by climbing up the stern using strategically placed hand holds. I love it for shallow streams, scouting, back channel exploring, anywhere pulling the skirt on a hardshell or rolling would be dangerous or a hassle. I added some thin foam padding to the seat and mounted some hooks to the underside of the hatch to hang bags rather than search for them in the hull. Excellent quality, tracks well and fast for its length.
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.
