Description

The RIB04S kit is a complete solution designed to optimize comfort and safety during your boat journey.
Specially designed for RIB boats and open hulls, it incorporates a sophisticated suspension system, an ergonomic jockey seat and a practical storage box.

Specifications

  • Advanced suspension technology: The suspension system reduces vertical acceleration caused by navigation, thus reducing G-forces and impacts on occupants’ spines.
  • High-quality materials: 6 mm and 8 mm thick 6061T6 aluminum structure, with marine powder coating for enhanced corrosion resistance. Components in AISI/SUS 316/316L stainless steel and plastic parts in POM or 30% glass-fibre reinforced polyamide 6.6 ensure durability and robustness.
  • Optimum comfort: Seat padded with marine memory foam and upholstered in high-quality marine vinyl, offering comfortable, long-lasting seating. The textured coating guarantees excellent grip.
  • Preload adjustment: Suitable for people weighing between 50 and 130 kg, with easy adjustment via a front knob.
  • Integrated storage box: Over 30 liters of storage space under the seat for your gear.
  • Conformity to standards: Conforms to ABYC H-31 guidelines and recommendations for type AO, ensuring safe and certified use.

Installation / Maintenance

Installation of the RIB04S is quick and easy. Preload adjustment takes just a few seconds, thanks to a knob on the suspension. Maintenance is minimal: just rinse with fresh low-pressure water after each use and apply silicone spray to the pivot points once a year. A protective cover is also included to protect the seat from UV rays when the boat is not in use.

Dimensions

Weight: 18kg / 39lb
Seating Height: 650mm / 26″.
Adjustable preload : 50-130kg / 110-285lb
Bridge interface plate: 400x230mm / 15.5×9

Our Review

Pros :

  • Significant improvements in on-board comfort and safety.
  • High-quality materials guarantee durability and corrosion resistance.
  • Easy to install and adjust.
  • Integrated storage box for extra storage space.

Cons :

  • A design that may seem massive to some users(see RIB03S for a lighter look)
  • Front grab bar not included, optional GR4 grab bar available.

Conclusion

The RIB04S kit is a complete and effective solution for improving comfort and safety on your sea outings. Thanks to its advanced suspension, ergonomic jockey seat and integrated storage box, it meets the needs of boaters looking for quality, durability and practicality. Despite its rather massive design, its many advantages make it a wise choice for equipping your boat.
