Configurable Physical Actions From Alarms

Relay Module

The Relay module is where software alarms can become physical actions on the boat, under rules chosen by the skipper and wired for the vessel.

Suite Overview Safety + Prevention

Physical Output Layer

From Alarm To Action

Any supported alarm, sensor event or safety situation can be configured to trigger one or more relay outputs. The intent is not to replace seamanship or certified safety equipment, but to make important actions faster and more repeatable when seconds matter.

For example, a MOB event can trigger a relay that deploys a long floating rescue line, activates a deck light, starts an external alarm or releases a SAR/rescue buoy if the boat is fitted with suitable hardware. Other boats might use relay outputs for pumps, sirens, ventilation, warning lamps or custom safety equipment.

Typical Relay Uses

MOB or deadman event: deploy a floating rope, SAR buoy, light or other prepared recovery aid.
AIS/RADAR collision alarm: trigger an external warning sounder or cockpit light.
High-water or bilge alarm: activate a backup pump, warning lamp or voice-alarm escalation path.
Gas, smoke or air-quality alarm: start ventilation or isolate/alert external equipment where safe to do so.
Watchkeeping or security alarm: drive a louder external alarm for waking a sleeping crew.

Configuration Philosophy

Relay actions are configured explicitly; nothing important is hidden or automatic by default.
Each relay can be mapped to selected alarm classes, sensor inputs or emergency states.
Outputs should be wired through proper marine-rated protection, fusing and isolation.
Critical actions should be tested regularly, just like MOB gear and bilge pumps.
The skipper decides what the boat should physically do for each situation.

Safety Boundary

The Relay module is a control output, not the safety device itself. The attached rope-release, buoy-release, pump, siren, lamp or other hardware must be mechanically reliable, correctly fused and suitable for marine use. The autopilot suite can command the output, but the installation quality determines whether the physical action works when needed.

Feedback And Comments

This project is still in progress, and I would genuinely like feedback on what is missing, what feels unclear, and what would be most useful offshore. The first sea trial is planned for the 2026 sailing season, and every comment is reviewed by me before it appears publicly.

Built For Singlehanded Offshore Reality

These public pages focus on what the suite actually delivers offshore: steadier steering, fail-safe automation, and practical offshore support that reduces workload without taking control away from the skipper.
