Oceansouth Boat Arch/Radar Arch – Free Standing Stainless Steel
What it is: A free-standing stainless steel radar arch designed to mount on boats with up to 87″ beam width. The frame uses a 1 1/4″ 316 stainless steel tube and offers adjustable height up to 43 inches. Best for boaters who want a durable, corrosion-resistant arch that can be customized to fit a mid-size to larger beam vessel without requiring a full top frame integration.
Who it’s best for: This arch suits boaters seeking a simple, robust solution for mounting radar equipment on boats with moderate to large beams. It’s ideal for anglers, day cruisers, and sport boat owners who prefer a minimalist, freestanding arch rather than a T-top integration.
Why selected: The corrosion-resistant stainless construction and adjustable height provide long-term stability in saltwater environments. Its compatibility with various radar setups makes it a flexible upgrade for many hull shapes. A potential limitation is the maximum height of 43″ which could be a constraint on taller vessels or very high radar units.
Caution: Ensure your vessel’s beam width remains within the 87″ limit and verify clearance for antenna rotation above the cockpit to avoid obstruction.
Dolphin T Top Radar Arch – Universal Fit
What it is: A universal-fit radar arch designed to reinforce Dolphin T-Tops, with adjustable mounting width and a heavy-duty anodized aluminum build. Includes a 20″x20″ aluminum plate and 2″ clamp, with U-shaped handles for added mounting security.
Who it’s best for: This option is best for boats that already feature a Dolphin T-Top frame seeking a reliable radar mounting solution without replacing the entire top structure. It’s also well-suited for lighter seas and standard cruising to maintain radar visibility.
Why selected: The universal fit and reinforced frame make it a practical upgrade for existing T-Tops, offering robust mounting points and corrosion resistance. A potential limitation is that the system is tailored to Dolphin T-Tops, which may not suit everything.
Caution: Check compatibility with your specific T-Top model and ensure the mounting plate aligns with the frame joints to avoid stress points on the top.
Lawaiʻa Dolphin Radar Arch Tower
What it is: A 54-inch tall radar arch tower with adjustable width spanning 82″ to 109″, crafted from anodized aluminum for marine durability. This tall, adjustable arch is designed to elevate radar and antenna equipment for improved range and visibility.
Who it’s best for: Suitable for larger boats or configurations needing substantial clearance and elevated radar mounting. Great for anglers or larger vessel owners who require more height and a broad mounting span.
Why selected: The height and width adjustability provide versatility across a wider range of boats. The anodized aluminum ensures resistance to corrosion and salt spray. A limitation is the need for precise boat width measurement to achieve an optimal fit.
Caution: Verify the required mounting height and ensure there is sufficient sea-room to rotate the radar without obstruction from rails or antennas on nearby structures.
Cruze Wakeboard Tower – Pontoon Boats
What it is: A wakeboard tower designed with pontoon boats in mind, capable of functioning as a radar arch. It offers universal fit for 80″–106″ beams and includes a mounting kit for immediate installation. Available in multiple colors for styling alignment with the boat.
Who it’s best for: Pontoon owners seeking a multi-use tower that supports wakeboarding and radar installation without specialized top structures. It’s particularly beneficial when a single platform serves sports and navigation needs.
Why selected: The universal fit and included mounting hardware simplify installation on pontoons. A limitation is that it is a wakeboard-focused tower, so it may require careful alignment to ensure radar clearance and balance on different pontoons.
Caution: Confirm your pontoon beam width and available mounting space to avoid interference with seating or railing components.
APT-F-150-01 Aluminum Radar Mount
What it is: A 6″ high aluminum radar mount designed for compatibility with Garmin, B&G, Lowrance, Raymarine, and Simrad radars. It is intended to be mounted on cabin roofs, radar arches, or flybridges for a stable, horizon-clear radar view.
Who it’s best for: This mount is ideal for boaters who want to upgrade or customize their radar setup without replacing an entire arch. It suits a wide range of vessels relying on a stable, centralized radar position.
Why selected: The broad radar compatibility and aft-leaning design (in some variants) can improve target visibility and reduce interference. Limitation: Some models specify aft-leaning designs and must be matched to the correct radar system and mounting location.
6″ Forward-Leaning Radar Mount – APT-F-LB Compatibility
What it is: A forward-leaning 6″ radar mount designed to fit APT-F-150-01, with an aluminum central light bar. Compatible with multiple radar brands including Garmin, Raymarine, Simrad, and more, offering flexible installation angles.
Who it’s best for: Boat owners who want an aft-leaning or forward-leaning option to optimize radar line-of-sight and reduce blind spots, particularly on vessels with shallow radar mounting angles.
Why selected: The 33-degree forward tilt helps improve target identification and horizon visibility. A potential limitation is that the forward-leaning design may not suit all radar layouts, so compatibility with your existing radar system matters.
Buying Guide: Key Considerations For Choosing A Radar Arch Or Mount
- Boat type and beam width: Ensure the arch or mount fits your vessel’s beam and mounting space. Freestanding arches work well on boats with sufficient open deck clearance; T-top replacements require compatible frames.
- Material and durability: Stainless steel offers excellent corrosion resistance for saltwater use; anodized aluminum reduces maintenance and weight while preserving strength.
- Radar compatibility and mounting style: Confirm radar model compatibility (Garmin, Simrad, Raymarine, B&G, etc.) and choose between roof/mast, arch, or tower mounting to optimize line-of-sight.
- Height and reach: Consider height to avoid interference with cockpit visibility and to ensure radar clearance when docking or passing under structures.
- Adjustability: Look for adjustable height, width, or tilt to tailor the arch to different boat layouts and radar units.
- Installation complexity: Some products come with comprehensive mounting kits; others may require professional installation for best results.
- Maintenance: Favor corrosion-resistant finishes and straightforward cleaning to extend the life of the arch and hardware.
FAQ
- What is the primary benefit of a radar arch on a boat? It elevates radar equipment to improve range, visibility, and target acquisition while keeping gear secure and accessible.
- Do radar arches fit all boat sizes? No, many arches are designed for specific beam widths and mounting configurations. Always verify compatibility with your hull size and deck layout.
- Is aluminum a good material for radar mounts? Yes, aluminum is lightweight, strong, and resistant to corrosion when properly finished, making it suitable for marine environments.
- Can I install a radar mount myself? Some mounts are DIY-friendly with pre-drilled holes and mounting kits; others may require professional installation for optimal alignment and safety.
- Which radar brands are commonly supported by these mounts? Typical compatibility includes Garmin, Raymarine, Simrad, B&G, and Lowrance, but always confirm the specific model compatibility before purchasing.
- What should I check before buying a radar arch? Check beam width compatibility, mounting surface, height clearance, and whether the arch needs to be freestanding or integrated with existing T-tops or wakeboard towers.
