I have some Army buddies that are coming back to Washington to get together in May. The plan is to do a kayak trip down a river. Probably a couple to three days. I don't have a kayak but a friend just gave me a sportsmans warehouse 9' pontoon. I think its the outcast ir-9 model. My question is if I took this would I be able to keep up decently with these guys in kayaks. They want to float the Chehalis which isn't really the top of my list. But it seems like an easy river to float. Just wondering if I should be looking for a kayak to buy as I don't want to be hours behind them. I don't believe anyone in the group is very experienced in kayaks except for one guy. Yes we will all be wearing pfds. Or at least I will.
