NEWS FROM THE RNLI LIFEBOAT TEAM IN DARTMOUTH F


ollowing on from last month, we are carrying on with the theme of the new RNLI


lifeboat in Dartmouth, the B-825, as there are loads of new features worth mentioning. Firstly, let’s look at the electronics. The Atlantic 85 is packed with modern, useful, gadgets. The first gadget is called a VHF direction finder. This means that the RNLI crew can call up the stricken vessel and ask them to transmit on VHF. This frequency is picked up by the lifeboat and displays a bearing to the casualty vessel. Let’s imagine a yacht race and all the sails are white. One vessel becomes a casualty and requests assistance from the RNLI. As all the vessels look alike it is very difficult to locate the stricken vessel. The direction finder sends the RNLI straight to it, thus saving precious time and effort on the part of the rescuing lifeboat. The system will also give a bearing to a transmitting EPIRB (Emergency Position Indicating Radio Beacon), and search and rescue transponders on larger vessels and many smaller leisure craft are seen on the radar screen. “We can see a lot more and find a lot more” says Dart RNLI Helm Rich Eggleton. The VHF follows all marine radio channels. All radio messages are recorded and can be played back, for example when the crew are otherwise occupied and miss the message received. Next we have SIMS. This is a

System. It is an electronic integrated bridge system that allows the crew to monitor, operate and control many of the lifeboat’s functions directly from their shock-absorbing seats. These

functions include: the navigation of the lifeboat, including direction finding, radar and charting; radio communications and CCTV; and the mechanics of the lifeboat including the engines and electrics. In addition to improving crew safety, SIMS allows better task sharing among the crew and negates the need for lots of separate systems and equipment, saving space and reducing weight. The Atlantic 85 also comes


with AIS (automatic identification system). This means anyone can search for and find the exact location of the lifeboat at any time when she is afloat and the engines are running. Finally, whilst The D class lifeboat has one solid state computer on board, the 85 has two. The crew sitting beside each other behind the helm each have access to an independent screen which can display the navigational charts, radar or VHF radio direction finding displays. The Coastguard is aware of what system is on board and can send the appropriate information to set up search patterns. What about comfort? Well,


the crew are in luck with the new vessel. She comes with air cushioned seats and toe retainers. All four crew are now able to sit down and be strapped in. Interestingly it is the 4th
