About

The electronic logbook for the skipper. The logbook is fully customisable and allows you to easily log events. With a fantastic light mode for daytime logging and the ingenious dark mode for night-time logging, you have your log under control at all times. The logbook is based on the two-phase model familiar from the paper form. First, the events are logged as they occur (on a notepad). At the end of the day, the collected log entries are then transferred to the logbook. This procedure has great advantages when keeping the logbook, especially on long voyages when a trip lasts several days. Almost everything about Ocean-Tools is unlimited, the number of logbooks, stages, log entries, crew, destinations and sails, to name just a few examples. This provides the best conditions for going on a long voyage. Ocean-Tools is also suitable for charter skippers who often change boats and crews. Try it out, it is currently the best logbook app for skippers on the market. We are working on making Ocean-Tools even better.
