Step 1 - Determine the mounting point for your top. The mounting point is where you want the frame to attach on the side of the boat. (The bimini top frame will mount at the same location on both sides of the boat.)
Step 2 - Determine the height of the top by measuring from the mounting point straight up with a tape measure.
Choose the ideal height to fit your needs:
A taller bimini provides more head clearance & room for a spotter or for boats with no or low side rails. A shorter bimini provides a sleeker look & ride and works well for boats with high side rails. A Pontoon Boat with 30" side rails and a 56" tall frame would provide 86" of clearance.
Step 3 - Determine the width of the top by measuring from mounting point to mounting point. Select the width that closest matches the width between your mounting points.
Pontoon boats are usually either 96" wide or 102" wide. Select the bimini width accordingly. Note: Bimini frames can "flex" out or in.
Note: 1 1/4" square tubing is available for 56" high pontoon bimini tops. This tubing matches the 1 1/4" OEM rail tubing available on most pontoons.
