Best Tablet For Marine Navigation

GPS is the most used method for marine navigation. However, it can be a bit of a challenge to use with a conventional tablet. This is where a marine tablet comes in. These tablets are specifically designed to be used on boats with added features such as a splash resistant casing and WiFi or satellite links. In this blog post, we will look at some of the best tablet for marine navigation on the market.

An Android device seems like the obvious choice in this case, but there are some big differences between iOS and Android that need consideration before choosing one over the other. I currently own both an Android phone (Samsung Galaxy Nexus), and an iPad 2, so am able to compare these two platforms fairly easily.

One of the biggest factors with any electronic device for boating purposes is water resistance/proof rating. There are conflicting opinions on this matter, but it appears that most people lean towards the idea of being able to use an iPad in the rain or out of the water. For example, if your boat is rocking back and forth in a bay, there’s a good chance you could get some splashes on your device while trying to read a chart, whereas a Galaxy Nexus might be too much of a hassle. If being able to use your device in wet conditions isn’t important to you though, then Android will have no issue since they are usually more affordable than iPads (and thus can be replaced more easily).

Another factor is screen size/resolution (which also ties into price). An iPad has such great resolution that when watching movies/TV shows I actually prefer to watch them on my iPad, even though it’s smaller. Talk about screen envy! On the other hand, an Android phone (or tablet) seems like a better choice for apps like charting or trying to read nautical books/charts since you’ve got much more screen real estate available. The weight of your device also matters; if you’re planning on making this your primary navigation tool then I’d recommend getting an Android tablet instead of an iPhone because Android tablets are heavier than iPhones, and that extra weight will be well worth it when you’re using them as electronic charts.
