I sail the Columbia River. I would like to find a chart plotter that
has chart tables that cover the tidal influence - which runs all the
way to Portland Oregon. I don't NEED it I WANT it.

I currently have a Garmin GPSMAP 492C. The last tide station it
displays in Knappa Slough, Oregon side. PC based programs seem to
have many more prediction points - as far east a Bonneville Dam.

Garmin has responded to questions but only with the answer that "the
eastern most tide station and prediction is Knappa Slough."

Any input?

I recently have and used the new Navionic (2007) charts with the Raymarine
C70 plotter. All tidal and current stations for my area are listed and
functioning well.
Check the navionic site for you area.

We use a Tidefinder, a handheld electronic tide calculator with more tide
and current locations than anything else I've seen. I haven't been able
to find it anywhere on the web except here (scroll to the bottom of the
page):

I think it's made in Bellingham, WA. It's well worth tracking down.

I use Wxtide, which is a windiws port of X-Tide.
http://www.wxtide32.com/

It seems to have lots of Columbia river locations, but I don't know
the area.

Cheers,
Michael Porter

I just purchased the Tidefinder TF-20 - in perfect condition, off
EBay. Now all I need is to figure how to program it. Do you have a
manual that I could copy?

For a very slick and relatively inexpensive solution, check out
http://www.toolworks.com/bilofsky/tidetool.htm freeware. I've used
Tidetool from the Bahamas to Maine and coverage is available for much of the
world, including the US West Coast. It runs on any Palm device with
sufficient memory and I much prefer it to the Garmin tide utility on my
176C. Makes a nice backup device and allows one to check tide (and some
current) info without having to scroll around on the GPS or chartplotter.
Also has many more intermediate stations than the Garmin.

Bilofsky's software is always good -- he's one of the originals! But
I use WX-Tide
http://www.wxtide32.com/
Has harmonic constants for lots of places -- all over the world, and
lots of display/printing options.

Cheers,
Michael Porter
