Let's see, on my boat
there are two chart plotters backed up by two handheld gps
systems backed up by two VHF
radios (in our areas the tides are broadcast on NOAA weather radio
channels), backed up by an iPhone
and a Blackberry, both equipped with tide apps. I've got eight electronic instruments on which I can retrieve tidal data without having to resort to an archaic table incapable of adjusting tides for exact locations in exact times.
The tidal data on the paper tide charts
is only good for the current
year and doesn't extend more than 100 miles from here. The tidal data on my iPhone
extends well beyond my expected lifetime and covers every tidal station on the west coast
, and every one of the 50 states that comprise the United States of America. American Samoa
is in there too, I've just noticed.
That little paper chart is sitting in the chart table in my nav station, which is inaccessible to me at the moment since I'm in my office. However, I can use the iPhone right now to tell me the exact tidal stage the moment I'm planning to leave the dock
this weekend, down to the inch.
When they stop giving out those paper chart books
free at chandleries, I won't miss them for a minute. I certainly wouldn't waste hard-earned money
