I am looking at a few different rafts now. one that has caught my attention is the maravia spider. I am also looking at the aire tributary 14.0 I am still having a hard time grasping the differences in the two boats. I know that I am looking to float the yak, methow, some of the coastal rivers and of course the sky and skagit. I am also hoping to go to montana in july and float a few rivers. I plan on doing the occasional overnight trip, but I am not sure the 3 or 4 day trips is in the cards for me anytime soon. I usually fish alone or with one other person and sometimes my 65lb lab. I am fairly experinced on the oars, but in no way a pro. all things being considered, would the spider be a better fit then the 14.0? I am concerned about the width of the spider at 5'6" possibly being too narrow to comfotably fish from. Also, is a narrow boat less laterally stable in whitewater? Would I have a higher chance of flipping it on its side? Any advice would be greatly appreciated.
