On my recent trip from the Chesapeake Bay to Ocracoke, NC I needed to know the tidal current prediction for a route for planning purposes. More often than not, the current predicted by my Garmin BlueChart App running on the iPad bears no resemblance to the observed current. Instead of favoring the run, it would roar against me. The Hampton Roads Approach have currents of two plus knots, and for a boat that moves at only 6.5 knots, it is important to time it right. The Garmin BlueChart was totally useless on that count. I love it for the charting, premium weather forecast, and Active Captain.
What has been your experience with this app? Is there a better way to predicting tidal currents? Any solution that does not involve being connected to the Internet?
