    boat covers

    I have a 1972 Glastron V 166 bowrider with a Mercury 1150 outboard. Who makes the best boat covers? I previously had a Riptide cover with a sewn in motor cover, trailerable...it was a great cover, but it looks like they don't make covers anymore. I want a 600 denier cover, UV protection etc. Thanks
