Ive got a wilderness systems 2 seater 13 and a half foot. Its a sit in kayak so i wouldnt take it in any swell, i have had it in the river and lakes when you get a few waves around a foot high and it is fine. Also done plenty of white water in it with no issues, never with fishing gear though. My old man has a perception 2 seater almost identical and i have grown up fishing out of it, probably 15 years old now if not older and no issues ever. I fish out of it all the time by myself, just have to put a big rock (5-10kg) right up the front to balance it out. Its great as you can throw fish gear etc in it with worry of anything slipping off. Perfect for rivers, estuaries and dams/lakes. Its also fast to paddle, with the missus in i can still out paddle mates in single seat sit on tops.
