Precision Marine Acoustic Monitoring

Listen to what your yacht is trying to tell you.

Designed for Boat Owners who want to focus on the adventure and have some extra assistance on board. Sentinel Sail continuously analyzes the acoustic and vibrational signatures of your vessel's critical systems, detecting anomalies before they become emergencies.

A Sixth Sense at the Helm

Installed into your dashboard console alongside your existing navigation suite, Sentinel Sail provides a real-time visual representation of your vessel's acoustic health.

Normal Operation

Acoustic signatures remain within the two defined safety thresholds, indicating all monitored systems are functioning optimally.

STATUS: NOMINAL

Anomaly Detected

When a performance signature spikes out of range, the system instantly alerts the helm, isolating the exact system requiring attention.

Anomaly Drill-Down

Shows the operator the specific acoustic frequency signature triggering the alert, comparing it to baselines to assist in finding the cause.

FREQ ANALYSIS

Comprehensive Vessel Monitoring

Our proprietary acoustic AI is trained to recognize the healthy "heartbeat" of your yacht, identifying subtle deviations long before traditional sensors trigger an alarm.

Drive & Propeller Health

Detects cavitation, imbalance, or entanglement from weeds and debris on the propeller before drivetrain damage occurs.

Hull Integrity

Monitors the hull's acoustic signature to detect excessive weed growth, barnacles, or impacts while underway.

Engine & Muffler

Analyzes normal engine operation and ensures muffler acoustics remain within safe ranges, preventing exhaust failures.

Fresh Water Systems

Identifies abnormal pressure pump acoustics or continuous running, instantly alerting you to low water levels or leaks.

Bilge Pump Usage

Tracks acoustic frequency of bilge pump operations, alerting you if usage falls outside of expected historical ranges.

Vital Equipment

Monitors the acoustic signatures of essential onboard equipment—generator, winches, and thrusters—to catch wear and faults before they leave you stranded.

This Is Not For Everyone (and we understand that): Optional remote health monitoring by sailboat and marine experts

Your privacy is important to you— and so is your time.

An optional feature is to enable remote monitoring of sailboat health by your selected Yacht Services and Repair organization. We provide them with a dashboard with which they can monitor the health of the fleet they support.

An Exclusive Invitation to Innovate

Sentinel Sail is a revolutionary technology currently in active development. We are actively onboarding dedicated sailboat owners (vessels 20 to 80 feet) into our Founding Captains Program to provide vital acoustic data from their boats. We are actively shaping the product details directly around your needs.

Our Philosophy

We believe in giving users the absolute benefit of the data and support they provide. Founding Captains will be the very first to benefit from the finalized technology.

Provide information about your interest. Space in the program is limited.
