The Atlantic 85 is the third generation rigid inflatable boat (RIB), in the B-class series of Inshore lifeboats, operated around the shores of the British Isles and the Channel Islands by the Royal National Lifeboat Institution (RNLI).

Like previous RIBs, it has a manually operated self-righting mechanism that deploys an airbag mounted atop the A-frame.

The lifeboat is also equipped with the RNLI's SIMS (ship information & management system) which provides the crew with combined chartplotter and AIS, radar and VHF directional finding capability.

To ensure equipment is kept to a high standard of repair, boats go through annual or bi-annual overhauls, and 4-year refits.
