Caution: The larger dome may require more secure mounting and electrical considerations on smaller pilothouse setups.
Buying Guide: Radar For Small Boats
What should you consider when selecting a radar for a small boat?
- Power and range: Higher kilowatt output and longer range help detect far hazards, but smaller boats may prioritize 24–36 NM ranges for practical navigation near shore.
- Deck footprint: Dome size and display visibility affect installation. Compact domes and accessible screens fit better on smaller boats.
- Integration: Do you want radar with chartplotter, sonar, or fishfinder in a single display? Consider GO or HALO series for integrated systems.
- Update speed: Fast refresh (60 RPM) improves collision avoidance in busy traffic. VelocityTrack or Doppler helps identify moving targets quickly.
- Ease of use: Clear interfaces and touchscreen options can reduce training time for crews unfamiliar with radar.
- Power and electrical load: Ensure your vessel’s electrical system can handle the radar’s power requirements and mount needs.

Frequently asked questions
- What radar range is best for small boats? – Ranges around 24–36 NM cover near-to-mid coastal needs and harbor approaches, while 48 NM is advantageous for open-water days.
- Do I need a separate chartplotter if I buy radar? – Not necessarily. Some models include chartplotter features, which is convenient for integrated systems.
- Is velocity tracking important? – VelocityTrack Doppler helps identify whether targets are approaching or receding, aiding quick decisions in dense traffic.
- What installation considerations matter most? – Dome size, mounting location, screen readability, and electrical supply are key to performance.
- Should I prioritize speed over power? – Speed (RPM) improves update frequency; power (kW) improves detection in poor visibility. Choose based on typical conditions you encounter.
- Are these radars compatible with existing gear? – Most listed models offer compatibility with common marine electronics, but verify integration with your boat’s MFD and transducers.
For small-boat operators, selecting a radar involves balancing range, update speed, display quality, and how well it integrates with navigation gear. The options above each present a distinct blend of these attributes to fit different boating styles and environments.
