recently created a frame for adding sail shades to my center console fishing boat. The T Top is nice for fishing but not ideal for snorkeling and site seeing trips. My prototype is on the front of the boat as shown in pictures. Was able to use four cleats on the boat and rods clamped to the t top to install without drilling holes in the boat. The frame is very sturdy thanks to installation of some 45 degree stiffeners. Maiden voyage is this weekend.
