The Modern Helm Station

The world of marine electronics has advanced dramatically over the past decade, and upgrading your onboard navigation systems can significantly enhance both safety and enjoyment on the water. Whether you are outfitting a new vessel or refreshing an aging helm station, knowing which upgrades deliver the greatest return on investment is essential for making smart purchasing decisions.

High-Impact Upgrades

A modern multifunction display (MFD) is the cornerstone of any well-equipped helm. Today's chartplotters from brands like Garmin, Raymarine, and Simrad offer stunning high-resolution screens, integrated sonar, and seamless connectivity with other onboard systems.

  • AIS Transponders: Pairing your MFD with a Class B AIS transponder is one of the most impactful safety upgrades you can make, as it allows other vessels to see your position on their displays while you can track traffic around you in real time.
  • Satellite Communication: For offshore passages, a dedicated SSB radio or a satellite communication device such as an Iridium GO! provides a critical lifeline when cellular coverage is unavailable.
  • The Fundamentals: Do not overlook the value of a quality VHF radio with DSC capability, a reliable depth sounder, and a wind instrument system for sailors. These fundamentals should be in excellent working order before investing in more advanced systems.

The Power of Integration

When planning your electronics upgrade, consider the integration between components — a fully networked NMEA 2000 system where all instruments communicate seamlessly is far more powerful than a collection of standalone devices.
