For superyacht owners, captains, and yacht managers, regulatory compliance is as critical as performance, comfort, and design. One of the most important and often misunderstood requirements for large yachts is the need for a SOLAS-approved rescue tender.
For superyachts over 500 gross tonnes (GT), specifying the correct rescue tender is a fundamental safety and certification requirement that directly affects flag compliance, vessel operation and crew readiness. This guide explains what SOLAS rescue tenders are, which superyachts require them, and what to consider when specifying a compliant solution, with insight from RIB-X, a specialist manufacturer of SOLAS rescue tenders for the global superyacht industry.
What Is SOLAS?
SOLAS, or Safety of Life at Sea, is an international maritime convention established and maintained by the International Maritime Organisation (IMO). It sets minimum safety standards for vessels, covering construction, equipment and operational safety. The first SOLAS treaty was passed in 1914 in response to the sinking of RMS Titanic which prescribed numbers of lifeboats and other emergency equipment along with safety procedures. Since then, SOLAS has evolved through multiple revisions and updates, becoming the most important international convention governing maritime safety and the carriage of lifesaving equipment on vessels worldwide.
For superyachts, SOLAS regulations determine when a vessel must carry certified lifesaving and rescue equipment. This includes life rafts, lifejackets and critically, a SOLAS-certified rescue tender capable of performing recovery and emergency response operations in real-world conditions.

What Is A SOLAS Rescue Tender?
A SOLAS rescue tender is not a standard superyacht tender. It is a purpose-built rescue craft designed and certified for emergency response, personnel recovery and lifesaving operations.
To meet SOLAS standards, a rescue tender must comply with strict international certification requirements.
These typically include:
- Certified stability and buoyancy
- A self-righting system, usually a righting-frame
- SOLAS-approved propulsion
- Certified tubes or foam fenders
- Clearly defined crew and passenger capacity limits
- MED, Marine Equipment Directive, approval where applicable
Unlike leisure tenders, every component of a SOLAS rescue tender must be documented, tested and approved for lifesaving use.
Which Superyachts Require A SOLAS Rescue Tender?
In general, a SOLAS rescue tender is required for:
- Superyachts of 500GT and above
- Commercially operated yachts
- Vessels required to comply with SOLAS Chapter III regulations
Exact requirements can vary depending on flag state, yacht usage and area of operation. For this reason, many captains and yacht managers consult specialist manufacturers such as RIB-X early in the specification process.
Key SOLAS Requirements For Rescue Tenders
Certified Construction And Approval
SOLAS rescue tenders must be constructed in an approved manufacturing facility, with full inspection documentation and traceability.
RIB-X SOLAS rescue tenders are manufactured in a Lloyd’s-approved UK facility and are fully SOLAS and MED certified, ensuring acceptance by flag states and classification societies worldwide.
Self-Righting Capability
A SOLAS rescue tender must be capable of self-righting if capsized.
RIB-X incorporates low-profile righting frames that meet SOLAS requirements while remaining practical for superyacht storage, launch and recovery systems.
Safe And Reliable Propulsion
SOLAS-approved propulsion systems are mandatory. Reliability, control and safety around people in the water are essential during rescue operations.
RIB-X typically specifies:
- Yanmar or Volvo Penta inboard engines
- Paired with Hamilton jet drives
Jet propulsion is preferred for rescue operations due to:
- Safer operation around people in the water
- Shallow-water capability
- Excellent low-speed manoeuvrability
Certified Tubes And Fenders
All buoyancy components must be SOLAS certification standards.
RIB-X SOLAS rescue tenders use SOLAS-approved Hypalon tubes or foam fenders, engineered for durability, impact resistance and long service life in demanding marine environments.
Why Choose RIB-X For A SOLAS Rescue Tender?
RIB-X specialises in SOLAS rescue tenders specifically for superyachts, rather than adapted commercial craft. Every RIB-X SOLAS tender is engineered to meet international safety regulations while also delivering the performance, comfort and aesthetics expected of a modern superyacht tender.
Dual-Use Capability
A key advantage of RIB-X SOLAS rescue tenders is their dual-use design. Each craft is capable of operating as:
- A fully compliant SOLAS rescue craft
- A practical superyacht tender for guest transfers, crew movements and daily operations
This dual functionality allows owners and captains to:
- Maximise space onboard
- Reduce the numbers of tenders carried
- Improve overall operational efficiency
Key Advantages of RIB-X SOLAS Rescue Tenders
- Lloyds-approved UK manufacturing
- Proven SOLAS and MED compliance
- Jet-driven propulsion for enhanced safety
- Low-profile designs suitable for superyacht storage
- Dual-use capability for rescue and guest operations
- Customisation options within SOLAS limits
- Direct collaboration with captains and yacht managers
RIB-X SOLAS rescue tenders are currently operating on superyachts throughout the Mediterranean, the Caribbean and worldwide.
Final Thoughts: Why Early Specification Matters
SOLAS compliance should never be treated as an afterthought. Specifying the correct rescue tender early in a new build or refit project helps avoid:
- Costly redesigns
- Tender garage or storage conflicts
- Delays in certification
- Operational compromises
By working with an experienced specialist such as RIB-X, owners, build teams, refit yards and crew can ensure their SOLAS rescue tender is fully compliant, operationally efficient and seamlessly integrated into the yacht.
