State-of-the-art inshore lifeboat

The Oddfellows arrived on station 11 July 2007 to replace RNLB Manchester Unity of Oddfellows (B-702). This latest version of the Atlantic 85 class had been in development by the RNLI since 2004. This lifeboat at the time of its arrival in Sheringham was the most modern state-of-the-art inshore lifeboats in the RNLI fleet. the new lifeboat was funded by the Manchester Unity Independent Order of Oddfellows, from which the lifeboat once again took her name. The organization also provided £68,000 for a new drive-on, drive-off launch and recovery carriage required for this larger boat. This new apparatus had a number of improved features such as illumination, and an enhanced hydraulic lifting device which, during rough seas, can be raised to an appropriate height enabling the boat to launch from the slipway at hightide without the bow being angled into the water. A wing-tank on either side of the trailer supplies each outboard engine with enough water to allow the engines to be started and warmed up on the slipway before launching.

Design

The Oddfellows is 8.44 m (27.7 ft) long and has a beam of 2.8 m (9.2 ft) and with the engine raised a draught of just 0.53 m (1.7 ft).[3] The propulsion is provided by two Yamaha inversion-proof 115 horsepower (86 kW) four-stroke petrol engines. The motors are capable of pushing the lifeboat through the water at speeds in excess of 35 knots (65 km/h; 40 mph). The lifeboat is launched with a crew of four aboard and uses a Do-Do (drive on - drive off)[3][4] trolley pushed directly into the sea by a Talus MB-4H amphibious tractor[5] via the station slipway.

Hull

The state-of-the-art carbon fibre hull structure has a foam core laminate that minimises the internal structure and helps the hull maintain its overall stiffness, and has very good impact absorption and recovers its shape after high impact loads which occur when the lifeboat rides through the waves at high speeds.[3] The carbon fibre is impervious attack by marine organisms and easily moulded into the complex shape needed to form the deep 'V' shape at the bow. The shape then falls away to a flat run to aft of the hull. This deep 'V' bow shape gives the boat excellent directional stability when underway and the flat run assists in getting the boat up on the plane quickly and on the occasions that the boat needs to be beached enables the lifeboat to sit upright.

Ballast

Located in the bow, water-filled ballast tanks provide the lifeboat with more stability and can be filled and emptied manually while at sea. This is achieved by use of a handle located near the helmsman which lowers a scoop to fill the tanks while the boat is underway. There are two fuel tanks, which are embedded in polystyrene, located on the port and starboard sides of the hull. The tanks can fuel each engine independently or one tank can fuel both engines if needed. The Oddfellows is also fitted with a manually operated righting system achieved by means of a gas buoyancy bag mounted on a framework above the engines, which, combined with her inversion proofed engines, allows her to remain operational even after capsize.[3]

Onboard equipment

The lifeboats onboard equipment includes the latest in electronic equipment including radar, a chart plotter and VHF radio direction finding equipment. Running around the outside of the hull is an inflatable tube constructed of tough Nylon weave. This tube, or sponson[3] is made up of separate compartments. If one of the compartments is accidentally punctured then the others will remain inflated. Should all the compartments become compromised the lifeboat would still be capable of floating without the sponson. The sponson allowing the boat to operate in rough seas and provides fendering when going alongside other vessels.

Central console

There are a total of four seats on the lifeboat but the boat is capable of carrying over twenty people if necessary. At the heart of the lifeboat there is a console which houses the helmsman's controls. This console also houses the illuminated compass, depth sounder, and various switches for controlling navigation lights. The engine start and stop switching is also located there along with individual tachometers motor high temperature warning lights. Behind the console is the seating for the crew, with the helmsman at the front, radio operator behind him to the port side, navigator to starboard and the fourth man's seat behind them. To secure the crew, each seat has foot straps fitted to the deck. The lifeboats water-tight VHF radio, loudspeaker system and hand-held microphone is located on the portside just behind the helmsmen position, although this can all be operated by a built-in radio speaker in the helmsman's helmet. The lifeboat also has a Global Positioning System and radar control to a display screen. The system provides the lifeboat crew with co-ordinates, estimated speed, and guidance to programmable waypoints. The Oddfellows also has DF radio which will indicate the compass heading that a radio contact is coming from.

Below the seats, there is access to the petrol tank filler caps along with a locker for gear such as a foot pump and an aerosol fog horn. A set of flares is stored aboard with red for distress and white flares which slowly descends on a parachute illuminating a large area. In case of technical difficulties with the navigation equipment, the crew can revert to using a set of waterproof charts of the local area which are also stored in pockets in the console. To the rear of the console is the 35 m towing rope on a reel which is used in conjunction with the tow bar to tow stricken vessels to safety.[3]

Stern roll-bar

To the stern of The Oddfellows there is a roll-bar or A-frame which houses and supports the self-righting bag at the top, navigation lights and radio aerial and uplink to the GPS. This roll-bar would also give some protection to the crew, motors and console should capsize in shallow water. The self-righting airbag is inflated using the compressed gas cylinders located at the base of the roll-bar. In the event of a capsize the mechanism is initiated with a handle located on either side of the boat outside of the stern, which when operated would cause contents of one of the gas bottles to inflate the airbag which will then cause the boat to roll the right way up.[3]

Service history

The Oddfellows was formally named at a ceremony which took place outside the boathouse on 15 September 2007.[1] The ceremony was attended by the helmsman, crew, station officials who all lined up in front of the lifeboat watched by over 100 members of the Manchester Unity of Oddfellows and members of the public. The lifeboat was blessed by the Rev. Mike Mcgill. Alison Adamson, secretary of the East Anglian group of the Manchester Unity of Oddfellows named the lifeboat and poured champagne across her bows.

The lifeboat was then launched on a demonstration before a large crowd who watched on.

First service

On 29 July 2007[1] The Oddfellows first service. This had actually taken place before her official launch and naming ceremony. The lifeboat was already at sea on an exercise when the Yarmouth Coastguard engaged her into an investigation of a reported capsized inflatable dinghy[1] about one metre long, found on the east beach at Sheringham. The lifeboat search the inshore waters from Sheringham in a westerly direction as far as Weybourne but nothing was found. Eventually the Coastguard beach team established that no one was with the inflatable and that there was no immediate danger and so the lifeboat returned to station.
