Lee, For some time, I have been a big fan of an iOS navigation app (iPad, iPhone) called "SEAiq." I run it on my iPad whenever I'm under way. It compares very favorably to Coastal Explorer. Recently, that iOS app became available for all platforms: Mac OSX, Android tablet, and Windoz. The User Interface is the same on all platforms, so you only have to learn to use the app on one platform to be able to use it on all platforms. In the US, it supports free NOAA and USACE charts. Across the rest of the world, it supports charts from several nation state authorities, including PRIMAR, ChartWorld, AHS, Bremer and VentureFarther. There are several versions of the app; there is a version for pleasure craft use for iOS that supports all of those chart sources, called SEAiq International. The professional SEAiq Pilot version is not cheap, and that's the one that currently supports multiple platforms; probably $200 or more; intended for use by professional harbor and offshore large-ship pilots. Very fully-featured. The cost of charts is determined by the nation state that publishes them. The only one I'm personally familiar with are Canada's, and they are quite expensive compared to the suite of free charts in the US. However, I believe it's true that the US model is the outlier; as most countries charge for their charts. Anyway, for what you have in mind, I'm quite sure SEAiq will be your best bet; less than $50, except for charts. Support is excellent, product has very extensive features that no other competing product offers on an iOS platform. Runs on iPad and iPhone, too, as an extra bonus. Supports NMEA0183 and N2K data feeds from your nav equipment, and displays what it sees. So, you can use an external NMEA GPS for location tracking in the app, or you can use the iPad's built-in GPS. Supports AIS features. Currently does not support Autopilot or Radar. Supports import of routes in .gpx format (via iTunes file transfer), so if as I do, you have a portfolio of routs in Coastal Explorer, you can import all of those routes into SEAiq and simply use them there. So as I see, way more features than anything else currently available for iOS platform, and I think, a real competitor for CE, since Rosepoint REFUSES to consider developing a non-Windoz platform. I have a product eval on my website, here: https://gilwellbear.wordpress.com/category/boat-technical-topics/computing-aboard/seaiq-nav-app-on-ipad/ <https://gilwellbear.wordpress.com/category/boat-technical-topics/computing-aboard/seaiq-nav-app-on-ipad/>. And, there's more about it on Panbo, too. What's interesting is, SEAiq is a very small shop (one guy, maybe), and he's done very sophisticated work on multiple platforms while preserving identical look and feel. I can't help wondering why Rosepoint - a much larger and more broadly financed operation - can't do that too. BTSOOM! Well, that's what competition is all about, isn't it!? No personal or financial interest in SEAiq; just a very happy user.
