Crossing an Ocean with iNavX

Note: I wrote this post in September while making passage from Vanuatu to Australia. I was all fired up about it until Vick read it and crinkled her nose (or something like that). I relegated it to the drafts folder and forgot about it until now. Recently a bunch of this year’s puddle jumpers have asked about this topic, and I figured “what the heck” I’ll just post it in case it helps someone. If you aren’t about to go blue water cruising, I suggest you give this one a skip. If you’re leaving tomorrow, and you don’t already have an iPad, likewise, skipperoo. But if you are using an iPad for navigation and haven’t already learned these tricks, I think it would be a really good idea to read this, digest it and then ask me to fill in detail for anything that wasn’t clear. Please do leave a comment so everyone can benefit from the process.

Manually Adding GRIBs to iNavx without Jailbreak

Back in July of 2011 I wrote a pretty geeky post about adding grib files to iNavx by first jailbreaking your iPad and then doing a series of complicated steps to get the gribs from Airmail (or wherever you download them from) to the iPad. I’m here to say that with newer versions of iOS (5+) there is an easier way.

First I should explain why this is a concern. If you are bluewater cruising, chances are you will not be able to use iNavX’s built in GRIB downloader. This means that you will have to download them through Airmail, zygrib, Ocens, mailasail, or what have you. These programs all have decent grib viewers but it is sometimes nice to overlay these on your charts. Enter the solution.

iNavX is (as I’ve previously mentioned) a terrific product. It’s one greatest shortcoming is it’s inability to import grib files when the iPad is not directly connected to the internet. Since this is going to be our primary electronic navigation device, I needed to remedy that before we left. Luckily, the solution is neither painful, nor overly technical (one in the same?). It does require jailbreaking your iPad though, so if you have trouble breaking the rules, you had better stop reading here.
