Electronic Tide tables ?

[NightCrawler]

We've used SailFlow for 4 years now. Tide tables are very complete using calculated points of interest to include many more easily named locations than some apps.
Here on the East Coast, knowing the hi/low tide and paying attention to River formed inlets for current, it's pretty easy to figure slack periods.
Their 36-48hr weather forecasts seem to beat most of the other apps we use as well.

So you are asking for information on current, not tide. Here in the Pacific Northwest, where current can be a huge issue, I've had great success with the Navionics electronic charts as they have information on current, both direction and speed, based on where you are on the chart at that particular time. The chart will also show you the same information for a future point in time. It's very helpful.

Ditto! Spot on where I travel!
