How to Make a 4-Bow Bimini Top
If you find you need protection from the sun, rain and spray while boating, a bimini is a great choice for your vessel. A bimini top made with Sunbrella® Marine Grade Fabric is durable enough to combat these elements and serve as a lasting addition to your boat. In this video tutorial we will show you patterning on the frame, sewing, installing a backstay slit, sewing zippered pockets and more. By the end of this project, you will have a custom, high-performance bimini top!
Before you can get started on the bimini top, you’ll need a bimini frame to pattern on. If you need a new bimini frame, Sailrite carries 2-, 3- and 4- bow frame kits in both stainless steel and aluminum. If you have a new Bimini Frame Kit and want to learn how to assemble it, be sure to first watch the “How to Build a 4-Bow Bimini Frame” video (300197XHT). It’s crucial to understand what size of bimini frame you’re working with because the number of bows in the frame must match the number of bows in the Bimini Skin Kit. This bimini kit will fit on a frame with a maximum width of 106 inches and a maximum fore and aft spread of 126 inches.
If you find that our Bimini Skin Kits are missing something essential to your unique project, just let us know and we would be happy to customize a kit for you! Our Bimini Skin Kits are great for replacing the fabric top on an existing bimini frame or it can be paired with one of Sailrite’s Bimini Frame Kits to build a new bimini from start to finish. Choose from Standard Color or Premium Color Skin Kits to ensure that you will have a professional-looking bimini durable enough to last season after season.
A Bimini Frame Kit and Bimini Skin Kit together from Sailrite gives you the great opportunity to customize everything from the material of the frame to the color of the canvas. Our frame kits come with all the hardware and supplies needed to assemble and install the bimini frame, while a paired skin kit includes the fabric and supplies needed to sew the bimini top.
Go ahead and get sewing, we’d love to see the finished product when you’re done!
