I can only speak of those I have owned. Due to mobility issues and lack of interest from the grandkids, I have sold mine. If I fell out and could not touch bottom, I couldn't get back in and I live in Gator country. It was a 15' Grumman and it did everything I remember them doing from my younger days. Flat bottom, moderate weight and added a transom for a TM. Moved well with a 35 lb thrust. Carried it in the P/U mostly but did have a jet ski trailer for it, but had to get wet loading it up. I stayed dry when carrying it in the P/U. Stood and fly fished. With my bad knees and back that speaks for it's stability. Miss it but all good things come to an end.
