Seago Sea Master Plus ISO 9650-1 TYPE 1 Life raft - Container

Seago Sea Master Plus ISO 9650-1 TYPE 1 Life raft 

Seago Sea Master Plus ISO 9650-1 TYPE 1 Life raft  are a flagship survival raft designed specifically for those who take their blue-water sailing seriously.

Whether you are a long-distance cruiser, a racing enthusiast meeting ISAF/RORC requirements, or operating a coded commercial vessel, the Sea Master Plus is engineered to provide the highest level of safety and stability in the harshest conditions.

Refined through years of collaboration with maritime professionals, the Sea Master Plus embodies the "Seago Spirit"—reliability when it matters most. This raft is built to the stringent ISO 9650-1 Type 1 standard, making it suitable for extended offshore voyages where high winds and significant wave heights may be encountered.

One of the standout upgrades for the latest model is the inclusion of a SOLAS-style inflatable boarding step. If you have ever tried a sea survival drill, you’ll know that hauling yourself into a raft from the water is the hardest part; this boarding step makes entry significantly faster and safer for all crew members

Seago Sea Master Plus ISO 9650-1 TYPE 1 Life raft Key Features

• Superior Stability: Features 4 x 55-litre lead-weighted, quick-filling ballast pockets (220 litres total) to prevent capsizing in heavy seas.
• Dual-Chamber Safety: Constructed with twin independent Butyl rubber tubes. Even if one chamber is punctured, the raft maintains full buoyancy for all occupants.
• Maximum Visibility: The high-visibility orange canopy is fitted with SOLAS-approved retro-reflective tape on both the top and the underside of the floor to aid rescue from the air or by sea.
• Thermal Protection: A thermo-insulated floor reduces the risk of hypothermia from the cold sea beneath you.
• Automatic Lighting: Equipped with an automatic SOLAS-approved flashing external light for night-time recovery and an internal light for crew comfort.
• Durable Materials: Made from 100% waterproof, "RipStop" Nylon for the canopy and ultra-robust Butyl rubber for the tubes.

Seago Sea Master Plus ISO 9650-1 TYPE 1 Life raft FAQs

What does "ISO 9650-1 Type 1" actually mean for me?

This is the "Gold Standard" for offshore sailing. Type 1 means the raft is designed for long-distance voyages where high winds and significant wave heights may be encountered. It is specifically engineered to be self-sufficient in harsh conditions.

Is this raft suitable for "Coded" vessels?

Yes, absolutely. The Sea Master Plus meets the requirements for ISAF, RORC, and other professional coding standards. Depending on your specific coding requirements, you may simply need to add an additional "over 24-hour" grab bag to supplement the internal pack.

What temperature range can this raft handle?

The Sea Master Plus is a "Group A" raft, meaning it is tested to inflate and function perfectly in temperatures ranging from -15°C to +65°C.

How does the raft stay stable in heavy seas?

The raft features 4 x 55-litre lead-weighted ballast pockets (the largest in its class). These fill instantly upon deployment to provide a low centre of gravity, significantly reducing the risk of capsizing in gusty winds or breaking waves.

What is the "Plus" in Sea Master Plus?

The "Plus" denotes several premium upgrades, most notably the inflatable boarding step. Unlike a simple webbing ladder, this step acts like a small ramp, making it much easier for a tired or cold person to pull themselves out of the water and into the raft.

What materials are used in construction?

Seago uses super-robust Butyl rubber for the twin independent buoyancy chambers. The canopy is made from 100% waterproof RipStop Nylon, which is incredibly tough and highly visible in the "High-Viz" orange.

Should I choose a Canister or a Valise? 

Canister: Best for permanent deck mounting (usually in a cradle). It offers the best protection against the elements and is ready for immediate deployment.

Valise: Better if you prefer to store the raft in a dedicated locker or below deck. It’s more portable but requires a clear path to the rail in an emergency.

What are the service intervals?

The Sea Master Plus has a 3-year service interval. This keeps your long-term maintenance costs down while ensuring the raft is always mission-ready.

What about the warranty?

Seago offers a massive 18-year warranty on this model. This is a testament to the build quality and provides peace of mind for nearly two decades, provided the 3-year service schedule is maintained by an authorised Seago service station.
