I have a Zodiac Cadet 260 (I'm sure that means 2.6 meters) but it's small 8' or so. I have a Honda 2hp 4stroke, I can get it to plane pretty easily and I'm over 150 lbs. It 's hard to keep it going strait though.
BUT, it rolls up nicely on the bow of the boat (26' capri).
It works for going boat to boat, or boat to shore so I'm pleased with it. Not to heavy, easy to roll up and fill up. etc.
