Navybuddies.com requires users to register in order to submit their own crew list information, while Decklog.com allows users to add records on behalf of friends and family members. In both cases, users must register and provide details about their service, including which ship they served on.
Both Navybuddies.com and Decklog.com are unofficial U.S. Navy crew lists. Official records of the Bureau of Naval Personnel are not public information, and naval veterans need not submit information for them. Unofficial crew lists allow Navy veterans to contact one another without having to ask the Federal Government to release records. Unofficial crew lists are usually categorized by ship and contain a history of the ship's service.
Navybuddies.com provides comprehensive information and crew lists for a number of ships, although the website does not offer a complete listing, since it gathers information from the individual veterans who sign up. Since Decklog.com allows a single user to add multiple records and notifies individuals who have had their records added, it benefits from a greater network spread. A Navy crew member who finds his name added on Decklog.com sees, at the bottom of the profile page, the name of the person who added the record. Once someone becomes a member of Decklog.com and adds a record, that record may not be altered afterwards.
