A boat shade canopy unit for a boat having a tubular frame disposed atop the boat comprising:

• a canopy support frame adapted to be disposed on the boat's tubular frame in a cantilevered fashion, said canopy support frame including two substantially parallel telescoping shade support members and a telescoping transverse support guide member disposed between said shade support members;
• a mounting system comprising at least two assemblies, each said assembly used to secure a respective part of said shade support members of said canopy support frame to a corresponding section of the boat's tubular frame, each said assembly comprising
• a grommet adapted to be placed between said respective part of said shade support member and said corresponding section of the boat's tubular frame, and
• a strap adapted to wrap around said section of the boat's tubular frame and said part of said shade support members such that said grommet is held in place snugly;
• a canopy disposed on said canopy support frame such that said canopy support frame can be extended such that at least a portion of said canopy extends outward from the boat's tubular frame.

A retrofit boat shade canopy unit for a boat having a tubular frame with at least two substantially parallel frame members disposed atop the boat, the retrofit boat shade canopy unit comprising:

• a canopy support frame adapted to be disposed adjacent the boat's tubular frame, said canopy support frame including two substantially parallel telescoping support members and a telescoping transverse compression member disposed between said shade support members to space apart said support members such that said support members substantially align with corresponding parallel frame members of the boat's tubular frame;
• at least two mounting assemblies, each said assembly used to secure a respective part of said support members of said canopy support frame to a corresponding section of the parallel frame members of the boat's tubular frame, each said assembly comprising
• a grommet adapted to be placed between said respective part of said support members and said corresponding section of the parallel frame members of the boat's tubular frame, and
• a strap adapted to wrap around said section of the boat's tubular frame and said part of said support members such that said grommet is held in place snugly;
• a canopy disposed on said canopy support frame such that said canopy support frame can be extended such that at least a portion of said canopy extends outward from the boat's tubular frame.
