Sgt Bob 2The B class Atlantic 85 is a rigid inflatable lifeboat, introduced into the RNLI’s fleet in the latter half of 2005 as the latest development of the B class. The name Atlantic is derived from Atlantic College in Wales, where the rigid inflatable was first developed. ’85’ is derived from a length of nearly 8.5m.

 

Fast, manoeuvrable and very reliable, the B class operates in rough weather conditions being operational in daylight up to force 7 and at night to force 6. Her design allows room for four crew members, more survivors and more kit than the station’s previous Atlantic 75 lifeboat.

Sgt Bob enginesShe is powered by two 115hp engines and has a stronger hull and greater top speed. The added radar allows the crew to operate more effectively in poor visibility and she also has VHF direction-finding equipment. A manually operated self-righting mechanism combined with two 115hp 4-stroke inversion-proofed engines keep her operational even after capsize. She is also capable of being beached in an emergency without sustaining damage to engines or steering gear.
