Custom Bimini Tops

Let us make quality a top or cover for your boat

You can’t just order a replacement boat canvas online and expect it to fit your bimini perfectly unless it’s directly from your boat’s manufacturer.

Generic bimini top canvases are often too short or too long, and even a few inches off can make installation impossible.

If you force an ill-fitting canvas onto your boat, it may sag, look unprofessional, or flap in the wind due to improper fitment. At Top Performance Marine, located on Norris Lake, we’ve heard from countless frustrated customers who ordered multiple replacement canvases—sometimes three or more—only to find they don’t fit their boat properly. Imagine ordering a canvas, unboxing it, struggling to fit it, sending it back, and then starting over. No, thank you!

Did you know your bimini frame was custom-designed for your specific boat? Manufacturers account for factors like height, width, shade coverage, and your boat’s unique layout, including door openings on pontoons, windshields, wake towers, and more. Ordering a generic replacement top is like buying a king-size sheet for a queen-size bed—our best analogy!

The most critical factor in replacing your bimini top is bow spacing. The key measurement is from the rear bow to the front bow, which determines the canvas length. Middle bows are also measured relative to the rear bow. Your bimini canvas is crafted with pockets that wrap around each bow, and if these pockets aren’t sewn in the exact right spots, the canvas won’t fit your boat.

When your factory canvas wears out, you have limited options. You can order a replacement from your boat’s manufacturer within the first 3–4 years of production, or you can rely on our expert team at Top Performance Marine, located directly on Norris Lake, to craft a custom replacement canvas or replace both the frame and canvas. Based on Norris Lake and proudly serving the greater Knoxville, TN area, we ensure your bimini top fits perfectly, enhancing your boating experience.

To ensure a perfect fit for your replacement bimini top, we need precise measurements and details about your boat. Here’s what to provide:

Length of your current bimini frame: Measure from the rear bow to the front bow in inches. This determines the canvas length.

Width of your current bimini frame: Measure from one mount point to the opposite mount point on your boat in inches.

Year, make, model, and HULL ID of your boat: The HULL ID is typically located on the right rear of your boat.

If your bimini frame is missing, measure the width from side to side between the old factory bimini mounting brackets. These details help us craft a custom canvas that fits your boat perfectly.

Sometimes in as little as 2-3 days. The lead time depends on our schedule, shop load and other factors. Just call or email us and provide the information outlined in "What Information Do We Need About Your Boat" listed above!

At Top Performance Marine, we can craft a custom bimini top for your boat, even if it’s never had one, the frame is missing, or it’s damaged beyond repair.

We specialize in bimini tops for houseboats, wake boats, cruisers, and fishing boats—if it floats, we can likely build a top for it! We can build or source frames from aluminum or stainless steel, offering both round and square bimini frames to suit your boat’s style and needs. Don’t worry—we’ve got you covered with a perfect fit.

If you’d like maximum sun coverage on your pontoon boat, a double top is the solution!

Can we add onto your existing frame and canvas? Yes, we can, but it’s often more expensive to pattern and fabricate an extension.

So, what are your options? We can create a second top to butt up against your rear top, or we can build a complete double top in various lengths tailored to your pontoon’s rail layout. Call us to discuss your project, and let’s find the perfect bimini top solution for you!

Can we make a bimini top for your wake tower? Yes, in most cases, we can! Call us, email us, or upload photos of your boat and project to get started. We’re here to help you find the perfect solution!

At Top Performance Marine, we craft bimini tops using premium materials like Sunbrella, Hydrofend, Weathermax, and Letom to ensure durability and style. Whether you’re looking for an affordable economy top, a mid-range option, or a premium-quality top, we tailor our work to fit your budget.

We use high quality UV-treated Solarfix and Sunguard thread for long-lasting stitching, unlike some shops that cut corners with cheap thread to save costs.

Poor-quality thread may fail within a year or two, leaving your bimini top’s stitching unraveling. That’s why choosing an established shop like Top Performance Marine, with a proven track record of delivering high-quality, long-lasting products, is the smart choice for your boat.
