Mob+ Wireless Man Overboard System
The Mob+ by FELL Marine is designed to automatically trigger an engine stop when an MOB event occurs, helping to prevent unintended movement and reduce risk. It also supports connecting up to four crew members, enabling crew safety and rapid response if someone falls overboard. The system emphasizes freedom of movement on deck while maintaining a rapid alert chain to the vessel’s control systems. Installers will appreciate straightforward integration with existing marine electronics and simple status indicators for quick verification during operations.
Ocean Signal RescueME MOB1
The rescueME MOB1 is a compact AIS man overboard device with automatic activation and a long 7-year battery life. It transmits location data to nearby AIS receivers and chart plotters, enabling nearby vessels and search teams to respond. With 24 hours of operational capability after activation, the MOB1 delivers rapid geolocation to assist rescuers during an MOB incident. Its integrated DSC transmitter enhances alert signaling across compatible marine electronics, improving coordination during emergencies.
EXPOSURE OLAS N2K
The EXPOSURE OLAS N2K integrates with NMEA 2000 networks to deliver a robust man overboard alarm system. Designed for engine kill switch compatibility and real-time alerting, this solution emphasizes crew safety on boats with multiple powertrains. The N2K functionality ensures seamless data sharing with existing networked devices, enabling quick cross-communication between MOB alerts and engine shutoff signals when needed.
Exposure OLAS T2
The OLAS T2 wearable tag provides wireless MOB alerts with real-time location tracking. This compact device is designed for crew reliability and ease of use, ensuring that a fall is immediately detected and communicated to the vessel’s MOB system. It is built to withstand marine conditions and includes waterproofing features to suit outdoor, saltwater environments. Real-time location updates support faster rescue operations and minimize response time on the water.
Exposure OLAS Multi Engine Connector
The OLAS Multi Engine Connector is designed for boats with up to three outboard engines. It enhances safety by coordinating MOB alerts with engine shutoff across multiple powerplants and integrates with the OLAS N2K system for streamlined data sharing. This solution is especially useful for larger, multi-engine vessels where synchronized actions are critical during emergencies.
Buying Guide: Key Purchase Considerations
When selecting a wireless MOB system, consider how it will fit your boat, crew, and typical operating conditions. Here are important factors and how they compare:
- Alert type and automation: Look for automatic engine kill or alert signaling. Systems like Mob+ emphasize automatic responses, while others prioritize quick-location sharing and DSC signaling.
- Communication network: AIS-based devices (MOB1) broadcast to nearby vessels, while NMEA 2000-integrated systems (N2K) ensure onboard compatibility with existing displays and controls.
- Battery life and maintenance: Long-lasting batteries reduce replacement frequency. Check standby versus active operation durations and whether devices support rechargeable options.
- Number of MOB tags or crew devices: Some setups support multiple crew members or tags, which is important for larger crews or family boats.
- Compatibility with engines: Multi-engine connectors allow automatic shutdown across several engines. Ensure compatibility with your boat’s make and model.
- Waterproofing and ruggedness: Marine environments require weatherproof designs and saltwater resistance for dependable performance.
- Ease of installation: Consider how invasive the installation is and whether it requires professional setup or can be done by an informed enthusiast.
- System integration: If you already use electronic charts or AIS receivers, prefer devices that integrate smoothly with existing equipment to minimize setup time.
- Plane of operation and portability: Wearable tags provide on-person detection, while fixed sensors focus on boat-based alerts and controls.
Choosing between a compact AIS MOB device and a multi-engine integration depends on vessel size, crew size, and typical voyage profiles. For smaller boats, a compact MOB1 or MOB-specific device may offer excellent coverage with straightforward installation. For larger, multi-engine boats, a system that coordinates engine shutoffs across multiple motors provides an added layer of safety by preventing drift after a MOB event. Assess your typical operating environment, electronics ecosystem, and crew training when deciding.
