The SMS launch alerts are directly linked to our crew pagers. When the crew are mustered by a pager call, it triggers an SMS launch alert. However, there are occasions when lifeboats launch without being paged. This could be because they are on exercise, are attending in support of another lifeboat or because the crew have been summoned by other means.
The SMS launch alerts can therefore best be taken as an indication of lifeboat activity rather then a definitive account of launches.
Due to operational reasons, the SMS launch alerts notifies you of launches after the launch has happened. in some cases the delay in the notification can be more than half an hour.
