The Sealogical Yacht Crew App is a simple way of recording crew member’s Hour of Rest, as defined by the Maritime Labour Convention, and managing crew leave. 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.
The Hours of Rest app checks the crew member's recorded Hours of Rest against the rules defined by the Maritime Labour Convention, and if minimum Hours of Rest are not achieved at the time of submission, an alert will raised to the user, with specific information about the period which does not satisfy the minimum requirement.

Crew members can also access their leave schedule and request leave from the app. This generates a request to the Captain or HOD who can approve or reject the leave request, with the status of the request being updated on the app.
