Shakespeare 4365 Marine Straight Mount
The Shakespeare 4365 is a straightforward 4-inch high, straight-mount option designed for ease of installation on deck surfaces. It is best for smaller radar units or compact boat setups where a simple, stable vertical mount is sufficient. The 1″-14 thread provides compatibility with common antenna bases. Best for small to midsize boats where space is limited and a clean, direct mounting point is available. A practical caution: ensure the mounting surface is sturdy enough to support the radar weight and wind loads without flexing.
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 to provide a clear horizon view and reduces shifting in high-speed conditions. It is described as easy to install with pre-drilled mounting holes, enabling direct bolts without modifying radar connectors. Best for boats needing a stable, raised installation with wide radar compatibility. Choose this if you want quick install with a robust, marine-grade base. Caution: ensure the pre-drilled holes align with your cabin roof or radar arch structure to avoid misalignment.
ZOMCHAIN Marine VHF Antenna Mounts (316 SS)
Though marketed for VHF antennas, this 316 stainless steel base is suitable for rugged marine antenna mounts where corrosion resistance is critical. The base measures a compact footprint with a 0.87″ – 10 thread male and a 3/8″ cable pass-through hole. It’s best for boats operating in saltwater environments seeking a durable, mirror-finished finish and multiple fastener options. Best for installations where stainless steel corrosion resistance is a priority. Limitation: it’s a base mount, so you’ll pair it with an appropriate antenna or radar apparatus designed for base mounting.
Boat T-top Clamp On Mounting Plate
This clamp-on mounting plate is CNC machined from high-grade aluminum with an anodized finish for added protection. Its large 4.5″ x 3″ base plate adds stability for radar or VHF antennas on T-tops or radar arches. Best for boats with T-top or arch configurations that require a clamp-style base rather than through-bolting. A potential limitation is the need for a compatible T-top or radar arch shape to anchor securely; verify tubing dimensions before purchasing.
MTAA APT-150-01 Aluminum Radar Mount
This APT-150-01 is a 6-inch high aluminum radar mount designed for wide compatibility with Garmin, B&G, Lowrance, Raymarine, and Simrad radars. It elevates the radar setup to reduce interference from structure and offers a modern aft-leaning design with a 25-degree rake for a contemporary look. Best for larger boats needing a taller, stable mount that improves horizon visibility. Limitation: ensure there is enough aft space on the cabin or arch to accommodate the lean without obstruction.
Buying Guide
What mounting location best fits your radar and boat type? Deck space, cabin roof, radar arch, and flybridge all influence the ideal mount. Consider the following:
- Radar compatibility: Check thread size (commonly 1″-14) and mounting pattern on your radar unit. Choose mounts with matching bases.
- Elevation and rake: A higher mount improves horizon visibility, while an aft-leaning design can reduce wind load and present a modern look; forward-leaning designs may suit forward deck visibility.
- Material and corrosion resistance: Marine-grade aluminum and 316 stainless steel offer different balances of weight, strength, and seawater resistance. Stainless is favored in saltwater environments.
- Installation complexity: Pre-drilled holes and clear mounting procedures save time and reduce modification risk. Some mounts require through-bolting or clamp-based solutions—choose based on deck structure.
- Maintenance and accessibility: Select a mount with accessible bolts, easy-to-clean surfaces, and space for wiring connections without strain.
FAQ
- What is the best mount for a small boat with limited deck space?
A compact straight mount like the Shakespeare 4365 is typically easier to install on tight decks and provides reliable support for small radars. - Do I need a stainless steel or aluminum radar mount?
Stainless steel offers superior corrosion resistance in saltwater, while aluminum is lighter and generally easier to weld or bolt to structures. Choose based on environment and weight considerations. - Can I mount a radar on a T-top or radar arch?
Yes. Mounts like the Boat T-top Clamp On Mounting Plate are designed for arches and T-tops, providing a stable base for elevated radar positions. - Is an aft-leaning radar mount better than a forward-leaning one?
It depends on deck layout and visibility preferences. Aft-leaning mounts can improve balance and appearance on certain boats, while forward-leaning designs may enhance forward visibility and wind clearance. - What installation challenges should I expect?
Common issues include misaligned holes, insufficient deck support, and wiring strain. Choose mounts with clear drilling patterns and plan routing before installation. - Are there mounting options that fit multiple radar brands?
Several aluminum mounts advertise wide compatibility with Garmin, Raymarine, Lowrance, B&G, and Simrad radars. Verify the mounting pattern and thread size before ordering.
