SEA.AI 4.3 Cuts False Alarms and Adds RGB Detection for Yachts

SEA.AI has released Software 4.3 for its Sentry and Watchkeeper machine-vision systems, introducing changes aimed at improving detection reliability in difficult sea conditions. The update reduces nuisance alerts from breaking waves, improves tracking when several targets are close together and adds colour-camera AI detection to Sentry.

Fewer nuisance alerts in rough water

SEA.AI says Release 4.3 changes how its systems handle breaking wave crests in certain rough-water conditions, reducing the likelihood that they are incorrectly flagged as objects. The objective is to improve alert confidence while preserving detection of genuine floating hazards and other targets ahead of the vessel.

For yacht bridges, reducing repeated false alarms can be operationally important because excessive nuisance warnings may distract watchkeepers and undermine confidence in an automated aid. The release therefore focuses on making the alert stream more useful rather than simply increasing the number of detections presented to crew.

Tracking improves in crowded scenes

The software also refines target tracking when several objects are close together, such as small craft, buoys or floating debris. SEA.AI says the system is better able to maintain them as separate targets, reducing lost tracks or situations where identities are swapped as objects move through the camera view.

That capability is relevant in busy approaches, anchorages and coastal waters where conventional radar and AIS information may be incomplete. Machine vision does not replace those bridge sensors, but it can add another observation layer for objects that are unreported, visually difficult or positioned close to other traffic.

RGB camera joins thermal detection

On Sentry installations, RGB Fusion allows the colour camera to contribute its own AI detections alongside information from the thermal cameras. SEA.AI says this can provide another source of detection in circumstances where thermal contrast is reduced, including high humidity or conditions in which target temperatures approach the surrounding environment.

Existing Sentry systems require an obstruction mask to be created before RGB Fusion is enabled, while new installations running Release 4.3 are supplied with the feature configured. The update also adds a 50/50 dual-view option, adjustable display scale and control over joystick-light brightness for bridge use.

Streaming and integration changes

Release 4.3 is designed to recover live video automatically after short network interruptions and to maintain more stable streams through source restarts. The extended interface also gains REST-based settings control, giving integrators additional options when incorporating SEA.AI equipment into larger bridge and vessel-management environments.

Watchkeeper receives five new thermal-contrast profiles so operators can adapt the displayed image to different weather and lighting conditions. SEA.AI notes that these profiles can affect detection performance, meaning bridge teams should select them deliberately rather than treating the visual setting as a purely cosmetic preference.
