Sailing - Concerned
If the ride up the Pacific coast is encountering problems, you will hear Sailing - Concerned. The song is in the same style, though not as cheerful, as Sailing - All's Well which will play if the ride becomes safe again, but if things take a turn for the worst, you may be subjected to Sailing - Bleak.
The song file is named 4000.MID. The title comes from the MIDI file's meta data.
