Description

Description

The RIB03S is a suspension kit with jockey seat designed to improve comfort and safety on board boats, particularly RIBs and open hulls.
This kit includes a technologically advanced suspension system and an ergonomic jockey seat, offering significant wave shock reduction and comfortable seating.

🔍 Features

  • Advanced suspension technology: The suspension system reduces the vertical acceleration generated by motor navigation, minimizing G-forces and impacts on the spine of passengers and crew.
  • High-quality materials: The structure is made of 6 mm and 8 mm thick 6061T6 aluminum, with a 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 guarantee durability and robustness.
  • Optimum comfort: The seat is padded with marine memory foam and covered with high-quality marine vinyl, providing comfortable, long-lasting seating.
    The textured coating ensures excellent grip on the seat. A GR3 front grab bar can be fitted as an option for additional safety.
  • Preload adjustment: The suspension can be adjusted for weights between 50 and 130 kg, enabling adaptation to individual passenger needs.
    Adjustment is easy, using the key supplied and attached to the suspension.
  • Compliance with standards: The kit complies with the guidelines and recommendations of ABYC H-31 for type AO, ensuring safe, certified use.

Dimensions

  • Seating Height: 650mm / 26″.
  • Adjustable pre-load: 50-130kg / 110-285lb
  • Weight: 16.5kg / 36lb
  • Deck mount plate: 290x225mm / 11.5×9″

Installation / Maintenance

Installing the RIB03S is quick and easy, using 8 M8 screws in your deck.
We can offer you watertight deck inserts and associated hardware, as well as extensions to adapt seat height and line of sight.

Shock absorber preload can be adjusted using a special 316L stainless steel wrench supplied and attached to the seat, for immediate availability.
A protective cover is also included to protect the seat from UV rays when the boat is not in use.

Maintenance is minimal: just rinse with fresh low-pressure water after each ride and apply lanolin spray to the shock absorber and spring.
Annually apply silicone spray to suspension pivot points and sliding parts.

  • High-quality materials guarantee durability and corrosion resistance.
