Rafnar 850 is Rafnar's 8.5-meter multi-functional general purpose support vessel. With precise scaling-adaptation of the ÖK Hull technology, Rafnar have produced a RIB that is ideally suited to the task at hand and provides the unique seakeeping and comfort qualities inherent in other Rafnar vessels built on the ÖK Hull. At 8.5-meters, Rafnar 850 is suited for various purposes, including search and rescue, man-over-board (MOB), coast guard, law enforcement, or the navy for rescue, patrolling, security, or surveillance purposes, both as a manned or autonomous vessel.

Rafnar 850 is an easily deployable and transportable tactical craft. At 8.5 metres, she can be neatly stowed on the deck of a larger vessel, and can be easily transported and deployed to remote operational zones. Rafnar 850 can be delivered with one of three propulsion options: jet drive, outboard, or stern drive. This fast, highly manouverable and stable craft exhibits all of the key ÖK Hull technology features and qualities of her bigger sister, Rafnar 1100.
