"Flotsom

Flotsom is a tool that manages daily life on board your typical
cruising vessel. We have been using it for the last 10 months to track
things like our daily log entries, our expenses, engine maintanence
records, fishing details, contact management and even recipes. The
idea was that we could have all this information in one easy to access
format that would minimize the time required to keep on top of things
while cruising. "
