This meticulously upgraded Coastline 6.5 RIB represents a rare opportunity to acquire a highly capable, professionally modernised performance RIB. Originally built in 1999, and extensively refitted from 2019 onwards, this 6.5-metre model now benefits from renewed structural elements, new console and seating, upgraded systems, and a comprehensive suite of electronics. The result is a robust, practical and confidence-inspiring RIB designed for coastal cruising, support duties, diving, fishing, or high-performance leisure use.
The hull has been strengthened with a 6 mm reinforced transom, enhanced deck-to-tube flanges, stern U-bolts and a customised drainage system with aft sump and RULE bilge pump. Above deck, the new console, twin jockey seats, and bespoke stainless-steel handrails give a modern, purposeful driving environment. The fit-out is completed by 1500g/m² Hypalon tubes with five chambers, reinforced wear panels and pressure-relief valves for ultimate durability.
Under the console sits a certified 138-litre stainless-steel fuel tank, feeding a fuel-efficient Suzuki DF115A (2019) with full electronic service history, digital instrumentation and GPS fuel metering. The electrical and navigation package is exceptional for a RIB of this size, combining B&G Triton instruments, N2K networking (wired & wireless), Bluetooth compass/heel sensors, Garmin Echomap chartplotter/sonar, dual flush-mounted transducers, and an Icom DSC VHF with long-range antenna.
Finished with a black/silver Flexiteek deck, epoxy paint system, updated deck gear, single-point lifting eyes, and full covers, this Coastline 6.5 stands out as a comprehensively sorted, turnkey RIB ready for immediate use.
Broker’s Comments
This Coastline 6.5 RIB is one of the finest examples of its type we have seen, clearly cherished by an experienced owner. It has benefited from investment in all the right places to significantly upgrade both structure and systems. The scale of work carried out since 2019 goes far beyond cosmetic refresh: the console, seating, tube reinforcements, electronics and transom strengthening make this boat feel closer to a modern commercial-grade RIB than a typical leisure craft of its age.
The Suzuki DF115A is an ideal power match, offering excellent reliability, lean-burn efficiency and strong performance. Combined with the large stainless fuel tank, this gives the boat impressive range for coastal passages or extended days on the water. The electronics package is unusually comprehensive and up-to-date, providing high-quality navigation, sonar and instrument data integrated across B&G and Garmin systems.
The addition of single-point lifting eyes, stern and bow Sampson posts, and through-hull lashing points suggest the boat has been prepared for both convenient handling and heavy-duty tasks. The epoxy-treated hull, Flexiteek decking, and custom overall cover round out an offering that is genuinely ready to step aboard and enjoy.
Engine hours: approximately 600
Cruising speed: 30–32 kts
Maximum speed: 40 kts
Hull weight: approximately 400–450 kg
Total weight (boat only): approximately 800 kg
There is no trailer included. The boat has not been formally weighed, but the figures above are accurate to the best of our knowledge. Based on these estimates, the combined weight of the boat and a suitable trailer would likely remain under 1,500 kg, meaning it can be towed by a standard car.
This from a marine industry professional who was the previous owner of this Coastline 6.5 RIB - "It’s a cracking boat – I’ve replaced it with the same again (the new Island 6.8 – identical hull). I’d go so far as to say, if someone wanted my new one, I’d have the Coastline back in an instant……….. not that the Island isn’t also a very good boat, just not sure the upgrade cost is justifiable."
If you are seeking a dependable, exceptionally well-equipped RIB with many big-ticket upgrades already completed, this Coastline 6.5 deserves serious consideration. Early viewing is strongly recommended.
