I've run a lot of big water in my skiff, it depends on your payload. If I have (3) of us all around 200 pounds that's about as big as I want going through standing 2' waves because you'll take on quite a bit of water. If it's a boat full of (3) above average sized humans you'll probably not like the Skiff. (2) people no problem IMO.
Would you feel confident in a skiff on a river on the OP/bigger water?
