The coxswain is in charge of the all-weather lifeboat and is in command when at sea.
He/she is responsible for all the operations connected with launching the lifeboat, ensuring the safety of all the lifeboat crew onboard.
It is the coxswain's duty to do all he/she can to safeguard and rescue those in danger. At the end of a rescue, the coxswain ensures that the lifeboat is ready for service and that the equipment is all in order.
Most coxswains are volunteers, although there are a few full-time paid coxswains.
Every all-weather lifeboat station has a full-time mechanic, who is responsible for maintaining the lifeboat’s engines and all the machinery at an all-weather lifeboat station.
At sea, the mechanic checks that the engines and other machinery are all working properly, as well as being part of the crew.
At stations that just have inshore lifeboats, volunteer mechanics make sure the lifeboat are ready for service through correct operation, maintenance and repair.
The helm is a volunteer who is in charge of the inshore lifeboat during launching, at sea and when she is being recovered and made ready for the next rescue.
The helm is responsible for the safety of the crew on board and for everything that happens during a rescue.
RNLI hovercraft are used to carry out rescues on mud, sand and shallow water, making them particularly useful on estuaries and tidal mudflats.
The hovercraft commander is a volunteer who is in charge of the hovercraft during launching, when on service and also at the end of a rescue when the hovercraft is being recovered to make sure it is ready for the next rescue.
The duties of a commander are the same as for a helm at an inshore lifeboat station.
Volunteer lifeboat crew members from all walks of life work with the coxswain or helm to operate the lifeboat during rescues and to ensure the safety of rescuees.
As well as going out on rescues, lifeboat crew members also commit to regular training in boathandling, radio communications, casualty care, navigation and radar.
The RNLI has 4,600 volunteer crew members around the UK and the RoI, 8% of whom are women.
