In a cantilevered watercraft canopy, a plurality of vertical supports provides support to a plurality of horizontal supports. First and second main struts are supported by the horizontal supports. First and second pluralities of arch members are affixed at a central attachment point to the first main strut and second main strut, respectively. The outer ends of the first and second pluralities of arch members support outer struts. In the first exemplary embodiment, the inner ends of the first and second pluralities of arch members are affixed to one another, and the main struts are affixed rigidly to the horizontal supports. In the second exemplary embodiment, first and second inner struts are affixed to the inner ends of the first and second pluralities of arch members, and the main struts are affixed rotatably to the horizontal supports. A canopy cover is affixed over the arch members and struts.
