You will find a lot of information about the Sea Cadet Corps on our wikipedia entry which looks like it has received a lot of work from NHQ:
There are two main websites for the Corps.
The first is the ‘public’ site available to all:
The second is the ‘internal’ training website which has all the training materials and more detailed instructions and policies.
This website is password protected and you will need your ‘Westminster’ log in details to get in.
Westminster is the computerised data management system that there Corps uses for centralised information, from everything from joining up to going on courses.
