Lalizas 20440 Life-Link M.O.B Throw Ring
The Lalizas Life-Link system is designed to be permanently mounted to the pushpit in its own soft, easy-clean PVC bag. It includes 118 feet (36 meters) of floating line connected to a buoyant PVC life-sling and a personal retaining clip for extra safety. Deployment involves removing the Life Link, attaching the line to a secure point, and throwing astern. The boat should circle the casualty to tow the sling in. Rescue is complete when the casualty is clipped into the Life Link and hauled aboard. Available in white and yellow; ISAF regulation compliant.
Best for: Boats that want a durable, permanently mounted MOB solution with a simple throw-ring approach. This kit is ideal for skippers who prefer a straightforward launch and tow method and need a clearly visible yellow option for quick recognition in daylight or spray.
Limitation: Requires secure mounting and a crew ready to throw and maneuver toward the casualty for retrieval. In rough seas, line management and visibility are critical to effective use.
Lalizas 73670 Life-Link White MOB Ring
This white variant mirrors the 20440 system with a durable, buoyant life-sling and floating line, designed for permanent pushpit mounting in a compact PVC bag. Deployment follows the same procedure: remove, attach the line, throw astern, circle and tow to the casualty, then secure on board. It’s a practical option when white color improves visibility against the sea. Meets ISAF regulation requirements.
Best for: Vessels that prefer a white MOB option for high-contrast visibility against blue water and a stable, permanent installation. Suitable for calm to moderate offshore and coastal operations where quick deployment matters.
Caution: As with any throw-line system, practice handling and line management are essential to minimize delays during a real MOB event.
Rock-N-Rescue Poseidon Side Opening Rescue Sling
The Poseidon rescue sling is designed for heavy lifting. It features a side-opening design with a spring closure, enabling the sling to be laid flat, slipped around the patient, and snapped shut. The harness uses 9,000 lbf (40.03 kN) webbing, with 5,000 lbf (22.24 kN) Mil-Spec hardware. This configuration makes it a robust option for more demanding MOB scenarios, such as rough seas or larger casualties, where a secure fit is critical.
Best for: Ski patrols, search-and-rescue teams, or larger small boats requiring a strong, side-opening rescue sling that can be applied quickly without fiddling with buckles. It’s better for heavy lifting and environments where durability is paramount.
Limitation: The side-opening design is highly effective, but practitioners should be familiar with the harness’s fit and ensure proper training to achieve a quick, secure closure in windy conditions.
Jon Buoy Inflatable Rescue Sling (Hard)
The Jon Buoy inflatable rescue sling employs automatic inflation, which can enhance buoyancy and visibility during an MOB event. Optional lighting and retro-reflective tape improve nighttime and low-visibility performance. This option is well-suited for crews seeking a fully self-contained response tool that activates with water contact and remains buoyant while awaiting retrieval.
Best for: Boats operating at night, in low-visibility conditions, or crews who value automatic inflation for rapid assist without manual inflation steps. It’s a robust pick for coastal and offshore operations where added visibility matters.
Caution: Dependent on functional inflation system; ensure regular maintenance and checks to prevent non-inflation in distress situations.
Lalizas Life Link Mini MOB 60′ Rope
This Lalizas Mini MOB uses a compact yellow bag and 60 feet (approximately 23 meters) of floating line. It is designed for versatile MOB retrieval, usable in hand or rail-mounted configurations. The shorter length makes it ideal for smaller boats, dinghies, or vessels with limited deck space where a longer line would be unwieldy.
Best for: Small boats, kayaks, canoes, or sailboats with limited deck space that still require a reliable MOB retrieval option. It’s a practical, portable alternative to larger, permanently mounted systems.
Limitation: The shorter line length reduces reach in larger vessels or wide-open water scenarios; consider pairing with other MOB equipment for broader coverage.
Buying Guide
What should I consider when choosing a man overboard rescue sling?
- Vessel size and mounting options: Permanent pushpit mounts suit larger boats; portable slings work well on smaller vessels.
- Deployment speed and training: Systems that deploy with a straightforward throw or quick-release are preferable for crews with limited MOB training.
- Visibility and buoyancy: High-visibility colors and buoyant lines improve recognition and floatation, aiding quick recovery.
- Durability and materials: Heavy-duty webbing and Mil-Spec hardware offer greater reliability in rough conditions.
- Night and low-visibility use: Consider inflatables with lights or retro-reflective features for nighttime rescues.
Should I prioritize one large system or multiple smaller options?
- For safety redundancy, having a primary MOB system plus a secondary lightweight sling provides coverage for different situations.
- On smaller boats, a portable 60′ rope sling may be more practical without sacrificing rescue capability.
How important is training and practice?
Regular drills improve response time and ensure the crew knows how to deploy, secure, and haul a casualty safely. Practice helps verify line tension, proper clipping, and boat handling during a MOB operation.
What about compliance and standards?
Look for systems that meet relevant maritime standards or ISAF/SOLAS requirements where applicable. Compliance helps ensure the rescue gear is designed to perform in regulated environments.
What is the right mix for a cruising boat?
- A permanent MOB throw-ring system for quick deployment, plus a portable sling for flexible use in various crew configurations.
- Consider adding an inflatable sling for nighttime or low-visibility rescues.
