The ILB is a more manoeuvrable boat than the larger All-weather Lifeboat.

With a top speed of 25 knots it is faster – if the sea-state permits the top speed to be reached that is! Being a small, open boat the crew are much more at the mercy of the elements than the crew in the All-weather Boat. This limits when the ILB can be used as it is unsafe if the weather is too rough.

The ILB has other limitations too. Being a smaller boat, the range of equipment carried is less than on the All-weather Boat, and the number of survivors that can be carried is less.

Usually the ILB launches with 3 crew members, led by the Helmsman who is in charge of the boat. Being a smaller crew each member has to multi-task, for example combining ‘driving’, radio communication with the Coastguard, navigation, look-out, first aid, setting up and managing towing.

Our current ILB has been on station since 2014, and is equipped with the latest navigation system.

Because of the risk of the ILB capsizing in poor weather all ILB crew members train to learn how to re-right the ILB should it overturn.
