APT-F-150-01 Aluminum Radar Mount 6″ Forward Leaning
This aluminum radar mount provides a compact, forward-leaning 6-inch elevation designed for marine-grade durability. It is compatible with Garmin, B&G, Lowrance, Raymarine, and Simrad radars, allowing for flexible integration across popular brands. Its lightweight build helps reduce overall mass while preserving strength for high-speed sailing and rough seas. Pre-drilled mounting holes enable straightforward installation without modifying radar connectors, making this option suitable for vessels that require a clean, quickly deployable setup.
Key considerations
- Compatibility with multiple radar brands ensures broad applicability aboard mixed-brand fleets.
- 6″ elevation offers a balance between horizon clarity and windage impact.
- Pre-drilled holes simplify installation and reduce the need for modifications.
APT-F-250-01 Aluminium PowerTower Forward Leaning 250mm
The PowerTower offers a forward-leaning, higher 250mm (10″) stance designed to maximize radar horizon visibility on larger boats. This solution is built by Scanstrut and features an internally mounted DS30 cable seal for a clean, weatherproof installation. Its design emphasizes minimal need for sealant, enabling simple setup on cabin roofs, flybridges, or radar arches. The PowerTower’s durability makes it well-suited for offshore or highly dynamic conditions where antenna performance relies on stable mounting and reliable cabling.
Key considerations
- Higher elevation improves radar range and horizon line in open-water scenarios.
- Internal DS30 cable seal reduces water intrusion risk without complicated sealing.
- Compatibility with a range of mast and arch configurations.
Scanstrut APT-150-01 Aluminum Powertower
This power tower variant provides a versatile mounting solution for radomes, open arrays, and compact satellite or TV antennas. Pre-drilled mounting holes facilitate fast installation, and the design includes a split bung system to prevent cutting the radar’s plugs during mounting. A key strength is its flexibility: multiple accessorized light bars can be bolted to the back of the PowerTower to support GPS, VHF, and navigation lights, enabling a consolidated, clean radar and electronics setup on a single mast or arch.
Key considerations
- Pre-drilled holes enable quick, precise mounting with minimal wiring alterations.
- Support for various accessories improves overall vessel electronics integration.
- Split bungs help maintain weatherproofing without modifying radar connectors.
SEAVIEW Modular Top Plate
The SEAVIEW Modular Top Plate is designed for compatibility with Seaview’s modular mounting systems, enabling the attachment of a wide array of radar, satellite domes, and antennas. The top plates are crafted in durable marine-grade high-density polyethylene and manufactured in the USA, ensuring robust performance in challenging marine environments. This option shines for boaters who want a highly adaptable platform that supports future upgrades, such as Starlink kits, additional radars, or security cameras, with a consistent, reliable mounting interface.
Key considerations
- Designed to work specifically with Seaview modular mounts for a seamless ecosystem.
- Durable, plastic-based construction resists marine wear while remaining lightweight.
- Wide compatibility supports evolving onboard equipment needs.
SEAWORTHY INNOVATIONS 6″ Tall Radar Mount
This 6″ tall radar mount from SEAWORTHY INNOVATIONS emphasizes true marine-grade construction with a 316 stainless steel body finished in a mirror-polished Electropolish. The design emphasizes durability by avoiding plastic parts that may crack and using welded metal components to resist corrosion and wear. The reversible forward or aft lean option increases installation flexibility on various hull configurations, allowing crew to optimize radar positioning for optimal horizon visibility and minimal interference with deck operations.
Key considerations
- 316 stainless steel construction offers top-tier corrosion resistance.
- Reversible forward/aft lean allows custom alignment to boat layout.
- Premium finish provides long-term aesthetic and functional durability.
Krypt Towers Radar Arch for Boat
The Krypt Towers Radar Arch is a robust, anodized aluminum system designed to fit boats with widest possible ranges, featuring adjustable width from 82″ to 109″. It ships with a transom fishing tower design option and heights of 54″ or 74″ for the radar arch. The arch is engineered for easy folding and storage, which is especially helpful on smaller boats or when transporting the vessel. This solution addresses both radar stability and space-saving needs without sacrificing strength or visibility.
Key considerations
- Adjustable width accommodates a wide range of hulls and configurations.
- Multiple height options help tailor clearance for sightlines, soffits, and antennas.
- Solid aluminum construction supports durable, long-term use at sea.
Buying Guide: Key Purchase Considerations For Boat Radar Mounts
Selecting the best radar mount depends on vessel size, radar type, and mounting location. Consider the following perspectives to ensure a durable, reliable setup:
- Compatibility: Verify radar brand compatibility and whether the mount supports both radars and accessories like GPS or VHF antennas. Modular systems like the SEAVIEW Top Plate offer broad future-proofing, while dedicated power towers emphasize single-purpose strength.
- Elevation and Lean: Forward-leaning mounts often improve horizon visibility on open water, but taller mounts can add windage and height clearance concerns in low-clearance areas. Reversibility (forward/aft lean) provides installation flexibility.
- Material and Corrosion Resistance: Stainless steel and marine-grade aluminum are common; pick units with corrosion-resistant finishes for saltwater environments. Avoid plastic-dominated constructs in harsh seaways.
- Installation and Cabling: Look for pre-drilled holes, integrated cable seals, and minimal wiring modifications. Sealed, weatherproof cabling reduces maintenance and failure risks at sea.
- Storage and Mobility: Some arch systems offer foldable designs to ease transport or shore storage. This is valuable for boats with limited dock space or coastal transport needs.
- Weight and Load: Ensure mounting hardware supports the radar’s weight and wind load, especially on high-speed boats and larger radars. Heavier builds are typically more robust but may affect sailing dynamics if not properly reinforced.
When evaluating options, balance the need for horizon clarity, ease of installation, and long-term durability. For fleets with diverse electronics, modular top plates and adaptable arches may provide the most future-ready foundation, while dedicated towers offer maximum rigidity for demanding offshore use.
