Hours of Rest App

For iOS and Android, The Hours of Rest app is a simple way of recording crew member's Hour of Rest, as defined by the Maritime Labour Convention.

Crew members can enter in their Hours of Rest direct to the app, and submit them to an email address of their choice. Sealogical subscribers assigned to a vessel will have their Hours of Rest recorded to the vessel account automatically - no need to email.

What Sealogical users are saying...

Sealogical is a very user friendly, informative and interactive SMS system. It is available to all crew members on board, who become familiar with it, due to their need to update their hours of rest and profiles on the system. Compared with paper based systems that I have experienced with other companies it is streets ahead.
