Oceansouth Boat Arch/Radar Arch
Features include a 1 1/4” 316 stainless steel tube frame, with adjustable height up to 43 inches and compatibility for boats up to 87 inches beam width. This freestanding arch is designed for small to mid-sized boats that need a rigid radar mounting option without drilling into the cockpit. Best for boaters who want a straightforward, corrosion-resistant frame that can be customized for radar, lights, or antennas.
Best for: Inline radar mounting on freestanding arch frames on compact hulls. Better for boats with moderate beam width and a need for adjustable height. Avoid if your boat requires a full-height, pencil-thin arch or has unusual beam constraints outside 87 inches.
Caution: Confirm the mounting points on your deck or gunwale to ensure a secure fit and avoid interference with existing rails or doors.
lawai’a Dolphin Radar Arch Fishing Tower
This 54-inch tall fishing tower elevates radar and antenna equipment for improved range and visibility. With adjustable width spanning 82 to 109 inches, it suits a wide range of boats and configurations. Polished stainless steel tubing provides robust durability in marine conditions, making it a strong choice for boats needing higher radar clearance without excessive weight.
Best for: Boaters with wide beam boats that need a tall arch to clear cabin structures or other deck equipment. Better for those who prioritize elevation and range. Choose this if your platform fits within the 82–109 inch width. Caution: Larger width range may require additional mounting hardware or structural reinforcement depending on hull design.
Seamax Cruze Wakeboard Tower (Radar Arch Ready)
Designed for pontoon boats, this wakeboard tower is engineered for stability and style, with flexible forward or backward installation to fit various layouts. It fits pontoon beams from 80 to 106 inches and includes a mounting kit for quick setup. The top bracket can act as a radar arch, enabling radar/antenna mounts without major modifications.
Best for: Pontoon boat owners who want a versatile, install-ready radar arch that also supports wakeboarding accessories. Better for those seeking a ready-to-install solution with universal fit. Avoid if your beam is outside 80–106 inches or if you require a dedicated, heavier radar arch instead of a multi-use tower.
ZJchao 316 Stainless Folding Mast Step
Made from 316 stainless steel, this folding mast step offers a polished finish for durability around radar arches, masts, and mirrors. Its versatile design supports a range of settings on ships, yachts, and cars, providing a compact mounting solution for radar arch integrations or mirror mounts.
Best for: Boaters who need a robust, corrosion-resistant connector piece for mounting components to arches or masts. Better for those seeking a versatile, compact steel step with reliable marine-grade construction. Caution: Folding features may require proper lubrication and periodic checks to maintain smooth operation.
Dolphin T Top Radar Arch Universal Fit
Designed for Dolphin T-Tops, this radar arch offers adjustable width for universal fit with 2 U-shaped handles and a 20″x20″ aluminum plate. Anodized aluminum construction provides durable corrosion resistance and long-term marine use. The clamp and mounting system work with a variety of T-Tops to secure radar equipment reliably.
Best for: Boats with Dolphin T-Tops looking for straightforward radar arch mounting and a sturdy, corrosion-resistant frame. Better for those who want easy adjustability. Caution: Ensure compatibility with your T-Top’s joint fittings and overall clearance around deck hardware to avoid interference with other equipment.
Buying Guide
Key considerations when choosing a small boat radar arch include material, mounting flexibility, and boat compatibility. The following questions help clarify options:
- What is the beam width of my boat, and can the arch accommodate it? Look for adjustable arches that specify compatible beam ranges.
- Do I need a freestanding arch or one that attaches to an existing T-Top or mast? Freestanding designs can be easier to install but may differ in stability from integrated options.
- Is the material corrosion resistance important for your water conditions (saltwater vs. freshwater)? Stainless steel and anodized aluminum are common choices.
- What radar or antenna sizes will you mount? Ensure the arch can support the weight and mounting hardware provided or required.
- Will installation require additional hardware or reinforcement on your boat? Some arches need extra brackets, backplates, or clamps for a secure fit.

FAQ
- What is the typical height range for small boat radar arches? Most adjustable arches offer height options from roughly 2 to 4 feet, with some models extending higher depending on design.
- Can I mount a radar arch on a pontoon boat? Yes, many arches are designed specifically for pontoon beams and include compatible mounting hardware.
- Are stainless steel arches better than aluminum? Stainless steel provides excellent strength and corrosion resistance, while aluminum is lighter and can resist corrosion when properly treated.
- Do radar arches affect boat stability? Properly installed arches should not significantly affect stability; however, additional weight aloft can change center of gravity slightly. Always follow weight limits and installation guidelines.
- What maintenance is needed for arches? Clean with fresh water to remove salt and grime, inspect for corrosion or wear, and tighten mounting hardware as needed.
