A convertible top canopy is pivotally attached to the hull of a multiple seat cruiser jet boat by a simple linkage system consisting of three U-shaped links each of which are attached at the base of the "U" to the canopy, the main link is pivotally and removably attached to the hull and another link is pivotally attached to the main link and the third link is pivotally attached to the second link and pivots to fold and lie against the deck on the stern of the watercraft. Tension straps at the stern and bow attach to the hull and forward and aft U-shaped links to position the canopy relative to the hull in the up position. The canopy is removable from the watercraft by releasing the main link and straps and usable as a cabana or umbrella on the ground by inserting a portion of the main link into the ground and tensioning the forward straps to stakes mounted in the ground.
