It's now my second season with this kayak, it's my first and only, bought it on length (storage issues) and price (discounted) I use it on sea, but don't venture far from shore because I haven't learned rolling and can't self -rescue. I'm not sure if it's me or the kayak, but since I can hip snap it, just can't roll , it must be me. It edges well, except sometimes it won't turn on edge (me again, conditions?) It tracks well enough but is really not meant for rougher waters and windy conditions when it becomes a bit hard to handle and is very prone to weathercocking. The plastic seems to be softer than a typical rotomolded kayak usually is because it peels like wax on contact with hard rough rock. Also when overturned gets very heavy because the front also fills with water (no front bulkhead), fairly easy to overturn it back from the side, bit impossible to drain lifting the bow from the water if no bottom to push against.
As I haven't had any other kayak prior to this one, can't really say if all of the above is just standard behaviour of any sit-in.
Also spraydecks are not easy to find due to large cockpit, but Hiko Basic CL110 works, probably neoprene Camel of the same size (Czech-made as well as the kayak).
All in all a proper sit-in kayak with at least some enclosed storage to protect critical stuff from splashes. Wouldn't take it on more than a day or two of touring, and definitely coastal tours only.
