Useful app.

This is a great app with a few minor shortcomings. Many of the islands are not named so a quick cross reference is slowed. It would be nice if the boundaries were slightly expanded and included more of Admiralty Inlet and Deception Pass. Also it would be nice if it extended up to Nanaimo. Nevertheless, very worthwhile.

I sail a small boat in these waters, and depend on the Canadian current atlas for every trip. This implementation is fantastic. And since you have to buy an update to the printed atlas every year for $20, the once off price for the app is well worth it. The app also lets you scan the currents hourly, instead of paging through the printed guide. Very impressive.

If you a PNW cruiser or racer, it’s a MUST HAVE!

As a Cruiser or a racer, navigating Pacific Northwest and British Columbia waters is challenging because of tidal currents. Luckily, this apps provides an hour-by-your forecast of tidal currents around San Juan and Gulf islands, making the navigation and planning much simpler.
