There are some brave, strong souls who roll their Sotars, RMRs, or Maravias, but it sucks to roll plastic boats. I think Aire is the exception on PVC/ Urethane boats being easy to roll up. I went with a buddy on the Deschutes last month. He rolled up his 14' Riken self bailer, set it on a receiver hitch cargo rack, along with the frame and oar blades. I could never do that with my Sotar. Mine is a trailer queen, all of the time.
Wishing I was on the river instead of surfing the web...
