I have bought two of these boats for a 15 yr old and 13 yr old to have something to do on our camping trips to the lake. We have used them several times and it has been a lot of fun. They are tall boys and are able to stretch their legs out completely.  The boys had a hard time paddling at first although we have gone canoeing several times and they are accustomed to paddling. We figured out that the boat is much easier to maneuver if you sit in it backwards so that the front of the boat isn't so high out of the water. I recommend this product for a fun time on the lake.
