I am interested in purchasing 2 kayaks to carry on top of my boat that I use in PWS. My main concern is that I want a VERY stabile craft. It will be used by teens and adults in calm water only, to go to and from shore and a little sightseeing close to shore. I would like to keep it close to 10 feet long. Also, I would like to keep it about $500 or less per craft. In this range, are most of them the same and it does not really matter what I get? Or does anyone have some advice for a rookie like me what to look for. Thanks for any input!
