Jack, the tide and current
updates are only $25. $99 buys you all of that AND updates of all US charts
on a DVD
, but if you have the time you can obviously still download all the charts
from NOAA for free. The previous free tide/current updates were a very generous policy--but $25 isn't totally unreasonable. $99 is called "Well, if you don't want to spend the time, we want some profit" and seems a bit less reasonable but I suspect a lot of folks would rather pony up $74 than mess with the cranky NOAA server for a couple of hours.

Acquiring Updated Tide and Current Predictions
The Tides and Currents for some U.S. Digital Charts will expire on December 31st, 2008 (or earlier: 2007 or 2006.)
There are three tide and current update options for registered users:
Purchase a Tides & Currents Update CD for $25. ---NEW 2009 Edition Now Available
This will update the tides and currents, but not your charts, through the end of 2009. ...
Purchase our new U.S. Boating

This will include all of the US waters charts (updated multiple times a year, LAST UPDATED Jan. 1, 2009) , the 2009 Tide and Currents,...
Tide & Currents Updates are not available for free download.
Please note that Maptech
is not able to offer free downloads of updated Tide & Current databases (including Offshore
Navigator Lite, and Chart Navigator Viewer.) These databases require a great deal of effort for us to produce each year, and with the resources needed to re-start a Maptech Navigation
based chart download site, we feel that it is a fair value to charge a reasonable price
for up-to-date tidal databases.
