ITU Legal Books (CD),
Radio Log Book

Vessels that sail internationally must have up-to-date legal books, as required by international conventions (*).

Whenever the latest editions of these legal books are published, we distribute them to our contracted vessels and also sell them to the general public. If you are interested in purchasing these books, please contact us by e-mail.

The Radio Log Book allows users to enter and save radio communication records for approximately three months, and is accompanied by communication-related regulations, MRCC lists (Maritime Rescue Control Center lists), etc. It has been well received for its useful and practical contents at a low price.
