4-Bow Marine Shade Protection

The 5 Oceans Marine 4-Bow Bimini is a heavy-duty shading solution designed for open boats, center consoles, and runabouts. This 4-bow configuration provides an extended coverage area and superior structural stability compared to standard 3-bow tops, ensuring more of your deck remains shaded during peak Australian summer temperatures.

Constructed from 310gsm Polyester Canvas, this bimini is engineered to withstand harsh marine environments. The fabric is both waterproof and UV-resistant, offering a UPF 50+ rating. The reinforced 25mm bright-dipped aluminium frame provides the rigidity needed for transit, while the rear support poles eliminate the need for extra straps at the back, keeping your fishing area clear.

Key Features & Benefits

• Quick-Release Thumb Screws: Unlike standard kits that use permanent screws, this kit includes ergonomic thumb screws and nylon nuts. This means you can quickly install or remove the bimini from your tinny without needing a screwdriver once the mounts are fitted.
• Integrated Storage Sock: The canvas features a built-in storage boot. When you want to clear the deck for casting, the bimini collapses directly into its own protective sock, preventing the fabric from flapping or getting damaged.
• Rear Support Poles: This 4-bow model includes fixed rear support poles instead of straps. This creates a stable "M-shape" frame that stays upright even when collapsed, which is a significant advantage for fishers who need moveability.
• Tapered Mounting Brackets: The mounting brackets are specifically tapered to match the angle of a boat's gunnels. This ensures the frame points inward correctly, reducing unnecessary stress on the hardware.
• High-Speed Engineering: This bimini is rated for speeds up to 40 knots (approx. 75km/h) when fully deployed on the water, making it suitable for fast commutes to your favorite fishing spots.

To find the right fit, measure the width between your primary mounting points on the gunnels.

Frequently Asked Questions

How do I make sure the bimini isn't "twisted" during install?

As shown in our installation video, you should measure from the back of the boat to your mounting marker on both sides (e.g., 1550mm). Accuracy here ensures the canvas sits square and tensions evenly across the frame.

Can I tow my boat with the bimini up?

For highway speeds (exceeding 80km/h), we recommend undoing the thumb screws, laying the bimini flat (either forward or backward), and securing it with jockey straps. The 40-knot rating applies to on-water use.

What tools do I need for the DIY install?

While a Phillips head screwdriver is included for the saddles, you will need a cordless drill, a 1/4" drill bit, a tape measure, and a permanent marker to set your mounting points on the gunnels.
