This is a 3 bow bimini top custom patterned off your existing stainless steel frame and boat for a perfect fit. We use quality Sunbrella canvas and Solarfix UV marine grade thread. This bimini also has zippered pockets all around for ease of installation and removal as well as a reinforced center bar pocket. This price assumes the boat is brought to Robie Canvas for the pattern and install. Additional fees apply if Robie needs to travel to the boat.
