Seaview 13.25 Inch Dual Mount Pre Drilled for Closed Dome Radars

Engineered for serious marine installations, the Seaview 13.25" Dual Mount is a robust, modular pedestal that positions your radar on a stable platform while leaving room above for additional electronics. With a height that optimizes dome clearance and line-of-sight, this mount keeps your radar dome steady in challenging conditions and provides a clean, professional look for your helm or flybridge setup.

Key features that set this mount apart

Pre-drilled bottom plate for fast, accurate installs — designed to fit most closed-dome radars, reducing drilling time and ensuring correct alignment without guesswork. This bottom plate is the foundation for a dependable, hobby-to-professional-grade installation.
13.25" tall modular design — tall enough to accommodate radar domes with above-mounted satellite domes or cameras, while keeping the radar at an optimal viewing height. The modular approach lets you stack electronics neatly while preserving access to cabling.
Top plate for satellite domes sold separately — the system is built to grow: mount your satdome or additional gear above the radar with a dedicated top plate (top plate required). This separation helps improve signal paths and cable management on open-water installations.
Designed for a wide range of closed-dome radars (up to 25") — the Seaview modular family is documented to support most closed-dome configurations, making this 13.25" mount a flexible choice for various radar sizes within the common 18"–25" dome category.
Part of Seaview’s trusted modular mounting ecosystem — built to integrate with other Seaview components for a clean, professional install on boat decks, pilothouses, or flybridges, with a focus on durability and long-term reliability.

Who this is ideal for

Boat owners upgrading to a closed-dome radar with an above-the-radar satellite dome or camera, seeking a tidy, durable mounting solution.
Installers pursuing a repeatable, scalable radar install on mid-sized to larger vessels where height, clearance, and cable routing matter.
Anyone who values a proven Seaview mounting system that can be expanded with optional top plates to accommodate additional gear as needs evolve.

Why this matters in the real world

Smooth, tool-reduced installation: pre-drilled bottom plates mean fewer pilot holes and a quicker, more accurate mounting process, which translates to a safer, more reliable radar setup at sea.
Clearance and accessibility: the 13.25" height is purpose-built to balance radar dome performance with convenient access for maintenance, wiring, and occasional adjustments without removing the dome.
Future-ready architecture: the modular top-plate option lets you rise above the radar with satellite domes or cameras, enabling enhanced situational awareness and easier upgrades down the line.

Practical installation tips

Plan cable routing through the pedestal to keep run lengths short and protect wiring from the elements. The modular design supports neat, unobtrusive cable paths as you add a satdome or camera above the radar.
Verify your radar size (within the 18"–25" closed-dome family) to ensure compatibility with the bottom mounting plate. If you’re adding a satellite dome, order the corresponding top plate to complete the stack.
Consider serviceability and future upgrades when choosing placement—mount in a location with easy access for routine maintenance and debris protection from spray or salt spray.

With the Seaview 13.25" Dual Mount, you’re choosing a proven, purpose-built solution for marine radar installations that emphasizes reliability, clean engineering, and scalable design. Built for the rigors of saltwater environments and backed by Seaview’s long-standing expertise in radar mounting, this mount helps you achieve a professional, durable installation that remains flexible as your gear evolves.
