Galvanic Voice

Description

What it is

Galvanic Voice is an intelligent voice alert system. It connects to your boat’s NMEA 2000 network and translates sensor data into clear, spoken warnings — by name — whenever traffic, environment, vessel or crew need attention.

One flush-mounted glass disc

A patent-pending glass-exciter resonator bonds a 20 W exciter directly to the back of the Gorilla Glass front face, turning the glass itself into the loudspeaker membrane. The same surface carries a 360° directional LED ring and a touchless gesture sensor. One sealed flush-mounted disc — no speaker holes, no grille, no separate display, no waterproof membrane to age. Designed for spray zones and washdowns.

Four domains, supervised in parallel, 24/7

• Traffic — AIS target tracking with context-sensitive collision-vector calculation; COLREGS-compliant crossing, head-on and overtaking classification; directional bearing alerts (“starboard bow”, “port quarter”) through the LED ring.
• Environment — wind shifts, gusts and rotations; sailing-polar refinement from your own trips; barometric pressure trends and storm warnings; coastal-proximity intelligence; sea-state aware fatigue and anchor logic; navigation-lights and day/night reminders.
• Vessel — engine health (temperature, oil pressure, fuel, RPM, hours); battery health and dropout prediction; depth and grounding prevention; anchor watch with drag detection, swing-circle analysis and neighbour monitoring; tanks; bilge; periodic maintenance reminders driven by NMEA 2000 hours.
• Crew — man-overboard detection via Galvanic Pulse bracelets; sleep, rest and BAC-equivalent fatigue index; watch management; periodic calls to action; emergency protocols using the IMO Bridge Alert Management escalation. On multi-unit installations, alerts addressed to the crew member nearest a Voice unit, on the unit nearest them.

All four run on roughly 1.1 W average power, escalating to spoken voice and visual indication only when the helm is being called to action. Alerts reach the crew within 500 ms of the triggering event.

Designed for two kinds of user

For the owner who reads the manual and exploits the system in all its power — and for the occasional crew member who has never seen it before and may never read a single page. Defaults are conservative, gestures are few, and the voice itself tells you what is happening and what to do about it.

Recognised alert convention

The alert grammar — four severity levels (Caution / Warning / Alarm / Emergency), the colour signatures, the single-gesture acknowledgement, the automatic escalation of unacknowledged alerts — is the one defined by the International Maritime Organization in Resolution MSC.302(87) (Bridge Alert Management, harmonised by IEC 62923). Anyone trained on a commercial bridge or a modern certified MFD already knows what red, amber and cyan mean here.

Multi-unit network

Install multiple Voice units across your vessel for full coverage. Any unit can be wired into NMEA 2000 — others receive NMEA data over WiFi. All units coordinate alerts automatically: acknowledging on one clears all.

What’s in the box

• 1 × Galvanic Voice main unit, flush-mount ring pre-assembled, with 1 m tinned-copper marine-grade power cable permanently attached (internal fuse — no separate fuse required).
• 2 × Galvanic Pulse bracelets, black, shipped in deep sleep mode — two as standard, six during pre-order (four extra free, €400 value).
• 1 × NMEA 2000 branch cable, 0.5 m, M12 5-pin Micro-C, with one male and one female connector.
• 1 × user card with serial number, secret code, and a QR code to the manual.

Installation

Typical install time about 10 minutes. Required: a 121 mm (4-3/4″) bi-metal hole saw — a globally standard size, stocked by marine chandleries and hardware stores worldwide — plus an electric drill. No screws, no sealant, no special tools. The unit uses a clamp-based flush mount; cut the hole, drop the unit in, tighten from below.

Free app — your phone or tablet becomes the MFD

Free iOS / Android app for phone and tablet — every device on board becomes a fully-featured MFD showing the same live vessel telemetry, charts, AIS traffic, weather, anchor watch and sailing performance as the Voice unit. No subscription, no in-app purchases. When the boat is online, the app continues to work as a remote MFD from anywhere in the world, end-to-end encrypted.
