Tide and Current Charts

[unbusted67]

Does any one know who publishes the charts with a graphical representation of the currents in a given body of water? The most familiar one being the chart of Long Island sound used in all of the Navigation classes. To clarify, I am not looking for tide tables, but rather a chart with a bunch of arrows on it.

Are you looking for Long Island or some other locale?

The Canadian Hydrographic Service publishes one that covers Georgia Strait and Puget Sound.

Starpath Publications (www.starpathpublications.com) publishes "Tidal Currents of Puget Sound" which I have found to be very useful. I am not aware of anyone who publishes such charts for other regions.

Are you looking for something like this: World Ocean Surface Currents (OSCAR - Ocean Surface Current Analyses - Real time) you are able to download data based on date, time, region or here: http://www.oceanweather.com/data/

Eldridge Tide & Pilot Book covers the entire east coast. Very good publication.

SailFlow, a subscription service, offers graphical displays of currents.

"in a given body of water" is the trick question.

In the US, that used to be NOAA, I think. We keep bumping things around, the Defense Hydrographic and Mapping folks got forced to deal with civilians, then their name and mission got bumped again...

But which body of water are you looking for? In some places, like Britain, that information will be "crown property" and you'll have to buy it.

I am not looking for any body of water in particular.

In this Navigation video that I am watching John Rousmanierre (sorry if I butchered his last name) has a chart of Long Island Sound and it has all of these arrows on it with different speeds written under them.

I know some charts, like the real one's published by NOAA, have little indicators if there is a place with an extreme current like Woods Hole in Cape Cod. But the one he has is chock full of arrows and when he closes it, it says "Tide and Current Charts" on the cover. A google search came up with nothing.

I love sailflow and those online indicators but have had no luck on the accuracy front with sail flow

Yes, the LIS charts were published by NOAA, mine is still that old since the geography and currents haven't changed. Since US government "copyright" belongs to the people not the state, you'll find the same charts in Eldridge and other reprinters.

Was he using a chartplotter, or computer? I use Maptech, and they show current, and speed on their charts.

Nope, paper chart booklet.

In The Netherlands the Tides and Tidal Currants atlas is published by the Royal Navy (publication HP33), updated every year. About $28, both paper and digital.

The paper charts with current arrows are in a set with one hour jumps in between.
