Oceansouth Freestanding Radar Arch
The Oceansouth radar arch is designed as a freestanding stainless steel frame, ideal for boats without a pre-existing hardtop or arch structure. It uses a 1 1/4-inch 316 stainless steel tube, offering corrosion resistance and robust support for radar domes and mast-mounted electronics. The arch is adjustable in height up to 43 inches and can be customized to fit boats with beam widths up to 87 inches. This flexibility helps ensure radar clearance and mounting stability on a variety of small- to mid-sized vessels.
Key features include stainless steel construction for marine environments, adjustable height to accommodate different radar antennas, and compatibility with boats of moderate beam width. Installation considerations involve securing the arch to the boat’s deck or rails and verifying radar clearance when turning or trimming at speed.
6″ Forward-Leaning Radar Mount
This forward-leaning radar mount measures 6 inches in height and uses an aluminum central light bar, increasing rigidity and reducing vibration at sea. It supports a wide range of radar domes from Garmin, B&G, Lowrance, Raymarine, and Simrad, making it a versatile choice for multiple systems. The 33-degree forward tilt helps target detection by presenting a clearer horizon view and minimizing blind spots, which enhances overall radar performance. The mount is designed to minimize movement in rough waters, maintaining steady radar alignment during high-speed voyages.
APT-F-150-01 Aluminum Radar Mount
This 6-inch high aluminum radar mount is designed for Garmin, B&G, Lowrance, Raymarine, and Simrad radars. It elevates the radar onto the cabin roof, radar arch, or flybridge to maintain a clear horizon view and prevent shifting in high-speed conditions. The installation is straightforward, with pre-drilled mounting holes that allow direct fixing without cutting radar connectors—a practical option for boat owners seeking a quick, stable setup.
Krypt Towers Radar Arch
Krypt Towers offers a tailless, transom-mounted radar arch with an adjustable width from 82 to 109 inches. The top bar is telescoping, enabling easy adjustment for different boat sizes and storage needs. Height options include 54 inches and 74 inches, making it suitable for small aluminum boats or larger craft. Construction features 2.25-inch 6063 aluminum tubing and anodized finishes in black or white. The design emphasizes a solid, rattle-free structure that supports radar mounting while allowing forward or rearward folding for space-conscious storage on deck or in a dockside slip.
APT-150-01 Aluminum Radar Mount (Aft Lean)
This 6-inch high aluminum radar mount features a 25-degree aft-leaning design for a modern look and improved radar positioning when mounted on the cabin roof, radar arch, or flybridge. It is broadly compatible with Garmin, B&G, Lowrance, Raymarine, and Simrad radars, aiming to minimize radar movement during rough seas. The aft-leaning setup can enhance visibility toward the horizon and help avoid interference with boat lines or cockpit hardware, while maintaining a clean, streamlined profile on small boats.
Buying Guide: Key considerations for small boat radar arches
- Boat size and beam width: Ensure the arch or mount supports your boat’s length and beam. Freestanding arches often require stern or bow deck anchoring, while arch-mounted options depend on existing rails or cabin structure.
- Material and corrosion resistance: Stainless steel offers excellent durability for saltwater use, while anodized aluminum provides a lighter option with solid corrosion resistance.
- Radar compatibility and mounting height: Confirm that the mount works with your radar model and choose a height that provides a clear horizon without obstruction from sails, antennas, or handrails.
- Forward vs. aft lean: Forward-leaning mounts can improve forward visibility and reduce blind spots; aft-leaning designs may help with radar stability and wind exposure patterns at the stern.
- Deployment and storage: Consider how easily the arch can be stored or folded for trailering or docking. Transom towers often offer foldable sections for compact storage.
- Installation effort: Look for mounts with pre-drilled holes and straightforward attachment methods to minimize drilling and wiring work on the vessel.
- Aesthetic integration: Select a finish and design that aligns with your boat’s color scheme and overall look to maintain a cohesive appearance.
- Weight and stability: Heavier stainless steel frames offer durability but require sturdy mounting points; lighter aluminum mounts reduce weight but still need solid installation to prevent vibration at speed.
