Key updates in the 2020 Captain Jack's include the addition of a new current station, Lawrence Point, on the east side of Orcas Island, and NOAA updated quite a few of the subordinate tide stations that appear on the daily pages to be reference stations. The page format was also modified to accommodate the new current station, allowing even more at-a-glance information crucial to boaters.
Captn Jack's includes daily tide graphs for NOAA’s Port Townsend and Seattle harmonic tide stations, allowing users to quickly visualize a day's tidal cycle. Height readouts for every other hour of the day are printed along the curves and are aligned above their corresponding times. High and low water predictions are aligned beneath the crests or troughs of the curves.
Each page of Captn Jack's shows the times and speeds of maximum floods and ebbs, as well as the times of slack water. Current speeds are given in knots, with asterisks used to indicate a current that is weak and variable. Normally there are two flood and two ebb currents each day, but some times and locations may show variations. The average directions of maximum flood and ebb current flow for each reference station are provided in degrees (true north) towards which the current flows.
Captn Jack's Puget Sound edition supplies data for the following stations. Harmonic stations are bolded, and subordinate stations are in plain text.

Harmonic Station predictions are based on 37 different cycles of the Earth, Sun, and Moon which affect the tides at that specific location. Subordinate Station predictions are obtained by applying corrections to specific harmonic reference station predictions. Subordinate station predictions are less accurate than harmonic station predictions.
