My buddies and I (all packrafters) scored a launch on April 20th. Most of us have Alpacas but a couple have the NRS packraft. There are six of us total so hopefully we split gear up enough. We have run up to class IV with A LOT of gear on those boats (think Coleman Stoves, cases of beer, steaks, small coolers, etc. Even survived a flip at the top of Squeeze Rapid in the Gunny Gorge, during which all of the afore mentioned gear stayed tied down to the Alpaca raft as it rode its way through the entire rapid upside down.
Or if enough flow we con someone with a raft into running support...
