After you have logged in, SeaLogs will take you to your Home Port showing a list of all previous log entries similar to below (sample is for vessel The Exampler).
Previous Log Entries list is like looking back through the previous pages of your logbook. As exampled below, these are broken up into Date, Master, Crew, Sign Off Comments, and then on the right side you can view or open a PDF version of a log entry, allowing you to print or email.

If the log entry you're looking for is already shown, you can either view that log entry by clicking on the black magnifying glass icon next to it, or you can export that log entry by clicking the PDF icon.
However if the list is too crowded, you can utilize the search function. On the header on the right-hand side, there is a field called Open Search Filters. If you click there, it will open a range of search options at the top of the page.

Searches can be conducted by Master, Crew, Log Date, or Comments criteria. Once you have made your selection, click the SEARCH button to begin.
If you want to reset all your search criteria, click the RESET button.
If you want to close the search panel, click CLOSE.
