A bimini boat cover is a type of partial covering that spans the deck of a boat, across where you would stand or sit when steering the craft. This type of cover can keep you more comfortable when you're on the water, as it blocks both harsh sunlight and water spray that might get in your eyes and on the boat's console. If you've never shopped for a bimini cover for a boat before, note a few important details to remember, so you know you get one that works for your boating needs in particular, and that lasts as long as possible.
