A four bow bimini top that covers 8 ft of deck length and adjusts across an 85 to 90 inch width at 54 inches of headroom, so it fits a range of beam measurements rather than one exact hull. Measure the deck length, width and height before ordering, because a bimini that is close but not right will not tension properly. The canopy is 600D yard dyed oxford, a fabric dyed at the yarn stage rather than printed on the surface, which is why it holds colour against sun and salt instead of chalking after a summer. It is built to take the long-term rigors of a marine environment, and the four bows supporting it are thick aluminum tube, rustproof and light enough not to load the gunwales. Mounting runs through deck mounts that bolt down quickly, and adjustable straps with hooks pull the canopy taut and keep it from flogging at speed. Two rear poles and two straps hold the aft edge, and releasing those straps is all it takes to fold the top down when a low bridge or a boat lift is coming. A dust-proof storage boot is included, wrapping the folded canopy so it stays clean through the off season. The whole top weighs 18.5 lbs and ships with 14 screws, 2 saddles, 4 deck mounts, crossbars and the bow tubes.
