As the heaviest and most robust 390 variant at 130 kg, the RIB390B is built for serious sea duty. It comes equipped with full front and rear cabins, a centre console, stainless steel backrest, bilge pump, and a 40-litre built-in fuel tank — the largest fuel capacity in the 390 range. Paired with 47 cm tubes and a 30 HP outboard rating, this is a true coastal workhorse ready for extended missions, commercial transport, and multi-day expeditions.

Technical Features

  • Hull: CE-certified deep-V fibreglass hull with a 1.85 m beam. The substantial 130 kg hull mass contributes to a planted, predictable ride in sea conditions, reducing the tendency to bounce in steep chop and delivering a reassuring feel at speed. Custom hull colours are available on request.
  • Tubes: 47 cm diameter Hypalon tubes — the largest in the 390 range — providing maximum buoyancy and impact absorption in challenging conditions. Three independent chambers for safety redundancy. Grab lines and lifting points are fitted as standard. Tube colour options available; PVC or Hypalon material can be specified on request.
  • Deck & Layout: Full front and rear cabins with cushions provide comfortable seating and dry storage. The centre console helm keeps controls within easy reach, and the stainless steel backrest adds durability. The 40-litre built-in fuel tank eliminates portable fuel jugs and extends operational range significantly.
  • Engine & Performance: Rated for outboards up to 30 HP (22.37 KW). The integrated fuel tank and heavier hull are well matched to the upper end of the power range, delivering confident cruising even in moderate seas. Estimated cruising speed 18–23 knots, top speed 24–28 knots depending on load and engine.
  • Safety: Bilge pump and self-bailing deck included as standard. Three chambers and 47 cm tubes provide substantial reserve buoyancy. Recommended equipment for offshore work: marine radio, GPS chartplotter, life jackets, and a sea anchor.
  • Manufacturing & Quality: Hand-laid fibreglass hull with vinylester resin for osmosis resistance. Tubes are hot-air welded for air-tight seams. Every hull undergoes a 48-hour quality soak test prior to delivery.
  • Certifications: CE certified under the applicable recreational craft directive. Hull warranty 5 years, tube warranty 2 years.
  • Customization: Hull graphics, tube colours, and console configurations can be tailored for fleet and OEM orders.
