Determine the width of the top by measuring from mounting point to mounting point (where you want the bimini to attach on one side of the boat to the same location on the opposite side of the boat).
Width selections below are given in 6" ranges. As long as your width measurement falls in the 6" range, your width selection will be correct.
Bimini frames can "flex" 3 inches out or in (i.e. a 54"-60" width frame assembled will measure approximately 57" in width but can be flexed in to 54" or out to 60").
Width is the most crucial measurement for finding a bimini top. While it is related to the width of your boat, this measurement is not the same as "beam" or boat width.
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 Center Console boat will need a taller bimini top, while a Ski Boat needs a shorter bimini for a sleeker look and ride.
A boat with 30" side rails and a 48" tall frame would provide 78" of clearance.
Determine how much of your boat you want covered by your top by choosing the length. Then select a manufacturer for your new bimini top made to your precise dimensions.
The mounting point is located approximately at the center of the bimini top. A 6 foot bimini covers 3 feet in front and 3 feet behind the mounting point.
If you are measuring your existing bimini, please note that some tops have a flap or overhang. Do not include this in the length measurement. Measure only from bow pocket to bow pocket.
