So far, my boats are car-top-able. I know both the Hyside paddle cat and the ST12 are less "flip prone" than the Hyside mini-max (10.5' x 5' with 18" tubes). Curious: what do y'all think between the paddlecat (frameless cat, 12' by 20" tubes, 1 inch shy of 5' wide) and the ST12 raft (12' x 2 inches shy of 6' wide; 19" tubes)???
