Bimini
With a bimini, also called 'bimini top' called, you create a solar roof on your motorboat. You can choose a stand-alone canopy with a stainless steel frame or a bimini with side pieces. This is also called a closed bimini. A bimini with sides increases the living space of your cruiser and is also very useful in lesser weather conditions.
The sides of the bimini are easily zipped off and can be windowed.
