Abstract: A combination radar arch and bimini top includes a radar arch securable on a boat deck over a boat cabin and a bimini top assembly secured to the radar arch. The bimini top assembly includes at least one bimini top base secured on the radar arch, a bimini arm pivotally connected to the bimini top base, and a spring-loaded roller assembly secured to the radar arch and including a canopy connected between the radar arch and the bimini arm. The bimini top base has a drive mechanism coupled with the bimini arm that is configured to displace the bimini arm between a retracted position and an extended position.

Abstract: A canopy extension system is cooperable with a support structure and includes a canopy arm securable pivotably to the support structure and a roller arm securable pivotably to the support structure. A roller is secured on the roller arm. A canopy is connected to the canopy arm at a distal end, is connected adjacent the support structure at a proximal end, and is connected to the roller between the distal end and the proximal end. A variation connects the canopy arm to a radar arch or the like with a spring-biased secondary canopy arm.
