What does that mean? Diameter is diameter.
With regard to the boat in question, I'd be very dubious of a boat of that size at that price. I suspect that if you were to calculate how much fabric a boat that size requires, and get a cost on that much fabric in a good quality PVC, it would probably be a fair bit more than the cost of this boat.
