Bimini tops offer protection from the sun when installed as a stand alone top.  These tops can be installed on nearly any type of boat from flybridge yachts and center consoles to sailboats.

A bimini can also be built with a camper back and removable curtains. This type of enclosure offers protection from the elements during foul weather.

A fishing top is basically a tall version of a convertible top designed for standing room on smaller runabouts used for fishing in inclement weather.  Clear vinyl is used in the forward section of the top for visibility and often includes a roll up section in the middle.
