We have an 11.5 ft Saturn Boat from Boatstogo.com. No interest in company. It has done well in fresh water for four seasons but is made of heavy duty pvc (decitex). It is light and has an air floor. It holds six in a pinch. It is also very inexpensive to purchase. I think ours was around $900. They offer smaller models. We also have a 28 year old Achilles that still holds air. It is a testament to the other advice rightfully given here that hypalon is a much better material. For us, the weight was important.
