B Class (Atlantic 85) Lifeboats

The Atlantic 85 is the third generation of RNLI B-class Atlantic inshore lifeboats that served the shores of the United Kingdom and Ireland as part of the RNLI fleet.

The hull is made from a carbon fibre and foam core laminate that minimises the internal structure whilst maintaining overall stiffness. The foam is a very tough material that has the ability to absorb and recover from high impact loads such as pounding through waves at speed. 

With a crew of four, and two inversion-proof 115hp petrol engines, the lifeboat is capable of speeds in excess of 35 knots, and is fitted with a manually operated righting system which, combined with inversion proofed engines, allows the boat to remain operational even after capsize.
