I am looking to get a new boat cover. I have had Top Gun for over 23 years on my last 2 covers. One of the places i went to for estimate recommended Aqualon over Top Gun ? They said it was a better material as long as it was vented which they would install 2 vents using tent poles to keep cover from sagging. my boat is 16 foot Sylvan Pro Select fishing boat. Looking for opinions??
