your product,,Let me begin by talking about customer service,,I was served by the name of (KIT),,she is a doll,,unbelievable service,and the Quality of the cover was very nice which i would rate as a 5 however it was HUGE big enough to fit a 26-30 ft pontoon boat and we ordered for a 20 ft,,I sold the boat a few days ago and did not notify iboats to complain only because of the great service that (Kit ) provided,,and the return of such a huge cover would cost me another $150.00..then i recieved this customer review email and thought I would respond just for future customers to get the right size cover,,I'm sure we double checked when we ordered that we had the exact cover for a 20ft Sylvan Trinidad.. any way if you need more percise info feel free to contact me again Andy
