ATLANTIC 85 ‘B’ CLASS INSHORE LIFEBOAT
Sheila and Dennis Tongue II
RIGHTING MECHANISMA manually operated righting mechanism can be deployed in the event of a capsize.
INVERSION-PROOFED ENGINESTwo 115hp 4-stroke engines give this lifeboat a good top speed. The engines are inversion-proofed so that they shut down in the event of a capsize and can be restarted after the lifeboat has been righted.
WHY ATLANTIC?The name Atlantic is derived from Atlantic College in South Glamorgan, where the rigid inflatable B class was first developed. ‘85’ refers to her length of nearly 8.5m.IDENTIFICATIONAll lifeboats have a unique identification number. The first part of the inshore lifeboat’s number indicates the class. All B class lifeboats begin with B and the numerals after the dash refer to the build number, so the first B class Atlantic 85 to be built was given the number B-801.
CASUALTY CAREMedical equipment is stowed aboard, including oxygen and full resuscitation kit,responder bag,multi-purpose ambulance pouch and stretcher.
NAVIGATIONLifeboats are fitted with the most up-to-date equipment, such as global positioning system (GPS), which our crew members are highly trained to use. A radar allows the crew to operate effectively in poor visibility aided by VHF direction-finding equipment. An electronic chart is also used onboard.
COMMUNICATIONVHF radio, intercom and hand-held VHF ensure communication, for example between the crew and Coastguard, remains constant.
LAUNCHINGSheila and Dennis Tongue II is launched by a TALUS MB-4H TRACTOR jointly developed by RNLI & Clayton Engineering LtdIt can be safely operated to a depth of 1.6m in level sea conditionsWeight: 9.38 tonnesPropulsion: 4 wheel driveEngine: Caterpillar 3114, 4 cylinder, 105hp - Diesel TurboMax. Speed: 22mphWinch Wire Pull: 5 tonnesIn the event of the machine getting into difficulties it can be battened down and left on the sea bed and recovered at low tide. The cab is specially designed to fully flood in order to provide stability, when submerged.Replacement Cost (2003) £250,000.
HELMA helm is responsible for the inshore lifeboat and the crew members onboard. They lead the rescue to ensure the lifeboat gets to where it needs to be and that casualties are given the appropriate care. A helm will have years of experience as a volunteer crew member, and be trained to the highest levels in areas including navigation, search and rescue, casualty care, leadership and team management.
NIGHT VISIONMany rescues take place at night and can involve being close to dangerous cliffs and man-made structures, or searching caves and crevices. Being able to illuminate the surrounding area with a searchlight, night-vision equipment and parachute illuminating flares, helps keep crew members safe as well as locate those in need of help.

In service at Looe Lifeboat Station since September 2016, the Sheila and Dennis Tongue II is a rigid inflatable lifeboat developed at the RNLI Inshore Centre at Cowes in 2005What kind of lifeboat is this?The Atlantic 85 is a B class inshore lifeboat, so she’s designed to operate in shallower water. There’s no wheelhouse, so the crew (usually 3–4) are exposed to the elements at all times. When it comes to heading to the scene, the Atlantic 85 is one of the fastest in the fleet: her top speed is 35 knots. She has inflatable sponsons and a rigid hull.How is the Atlantic 85 launched?She is taken to the sea from the boathouse on a carriage, pulled or pushed by a tractor.What sort of rescues is the Atlantic 85 designed for?Inshore lifeboats like this one are ideal for rescues close to shore or cliffs, among rocks, or even in caves. They can handle fairly challenging open sea conditions too – the Atlantic 85 can operate in a force 7 in daylight and at night to force 6 winds.
