I am looking to cover my boat. I have been using the blue tarps which last about 3 months and then throw them away. Got a price of $3200 to cover a 27' center console and have looked online at boat covers direct, $800. The material they use is 6 oz. poly-guard acrylic coated marine-grade polyester. Anybody used these covers? Any input appreciated. $3200 is a bit pricey.
