Attwood Bimini Tops

What Are Attwood Bimini Tops?

A bimini top is one of the most practical upgrades any boater can make. Attwood bimini tops — and the compatible replacement fabrics, frames, and components that make up this category — provide an overhead canopy that shields you, your crew, and your gear from the sun's harsh UV rays while out on the water. Whether you're fishing all day on a center console, cruising on a pontoon, or running a classic runabout, a quality bimini top dramatically extends your time on the water in comfort.

A typical bimini consists of two main components: the frame and the fabric canopy. Frames are most commonly built from anodized aluminum tubing or stainless steel tubing, both chosen specifically for their resistance to corrosion in marine environments. The canopy fabric is stretched over the frame and typically made from UV-resistant, water-repellent materials — from durable solution-dyed polyester to premium marine acrylic fabrics like Sunbrella — engineered to resist fading, mildew, and rot over years of open-air use.

Key Considerations When Choosing a Bimini Top

Selecting the right bimini top comes down to a few important measurements and material choices:

• Number of bows: Biminis typically come in 2-bow, 3-bow, or 4-bow configurations. More bows mean a longer top and greater coverage — 4-bow tops are popular on larger center console fishing boats, while 2- and 3-bow options suit runabouts and smaller vessels.
• Width: Match the width of your bimini to the beam (width) of your boat's seating or helm area. Widths typically range from 54" to 96" or more.
• Height: Height is measured from the mounting point up, not from the boat floor. A taller frame gives passengers more headroom, though this can reduce the overall shade coverage footprint.
• Frame material: Aluminum is lighter and more affordable, while stainless steel offers superior corrosion resistance — an especially important factor for saltwater boating.
• Fabric material: Premium acrylic fabrics offer excellent UV blockage, breathability, and mildew resistance, while heavy-duty polyester options deliver strong tear resistance and water repellency at a competitive value.

Top Brands in Attwood Bimini Tops

Carver Covers is the dominant name in this category and for good reason. Carver designs and manufactures its bimini tops in Landrum, South Carolina, offering an impressive range of frame styles — round tube, square tube, stainless steel, and tower-mount — paired with canopy fabrics including their proprietary Sun-DURA® and premium Sunbrella®/Outdura® options. Their double-walled main bows add structural rigidity, and stainless steel snap hooks and eye straps at key stress points further enhance durability.

Taylor Made is a long-respected marine brand known for quality boat tops and accessories, offering bimini solutions built with the same attention to marine-grade construction that has made them a trusted name on the water for decades.

Replacement Fabrics & Frames

Not every bimini top purchase has to be a full system. If your frame is still structurally sound, a replacement canopy fabric can breathe new life into your setup. Attwood bimini top fabrics are available in multiple UV-resistant colors, allowing you to match your boat's color scheme while restoring the shade and weather protection your top was designed to provide. Conversely, if the fabric is intact but your frame has corroded or bent, replacement bimini frames are available separately as well, making it easy to keep your setup in top condition without a full replacement.
