I love my Jacks Plastic Welding Culebra, 11' and has thwarts, so all you need is a normal raft frame.
I can self support for 5 days in it, super fun, light, can be taken apart and
be packed as luggage on a plane, and can handle bigger white water then you would think from the size. I have the optional cargo slings which allows me to carry a lot of gear if I want to, least for a boat that size. Cargo slings are good for grabbing a swimmer to.
We can't always agree, but we can still be civil to each other.
