Trouble deciding on Ipad Nav apps

[Kd9truck]

Great post! My fav is navionics thanks all, Following

I think the AIS function in Navionics is very basic - not really useful. So I use iSailor for that: much, much better. Although my iPad has GPS, I have a wifi link with the AIS Transceiver that supplies position, etc.. Works very well and is more friendly to your battery.

My iPad lives under the sprayhood in a special frame and has a watertight socket. Shade is sufficient to keep the screen visible even in plain sunlight.

Which if any of these programs feature
“Chart Quilting” so you can’t run off the edge
of the chart and then have to load the next one manually?
I have seen this with INavx and makes for some real
Pandemonium at all the wrong times
Cheers

Navionics is great for east coast US, but you want Explorer Chartbooks for Bahamas, and I have that on my helm chart plotter in C-Map. If I only had an iPad, I would get an app that will allow you to use Explorer if you're headed to the Bahamas. From a usability standpoint, Aquamaps is probably easiest, but there's not much difference really between three. Also, if I only had an iPad, I would get some sort of back-up device. Batteries die, devices die; I had a Furuno chart plotter die on me once, leaving the iPad as my primary.

AquaMaps has the Explorer charts for the Bahamas.

Navionics, AquaMap and ISailor are all good for vector charts. Fir the US, these are all based on the official NOAA data, and while they may each display it differently, the underlying accuracy and completeness should be basically the same (notwithstanding a few omissions that we’ve noticed in the Navionics “translation” of NOAA data this year).

For raster charts, check out SEAiq USA. I find the interface much easier to use than iNavX, and the (human edited/drawn) raster charts sometimes provide a very different level of awareness than the vector charts, especially in unfamiliar areas. Not so much for basic depths and contours, but unusual/atypical geographic features will usually be blindingly obvious on the raster charts, while the same feature may be more subtly indicated by an inconspicuous symbol, and boundaries may be harder to interpret from the display in the vector charting apps.

On my delivery iPad I have: Navionics, primarily for the sonar charts and crowd-source info. I also have iNavX loaded so I can see the old raster charts.



My benchmark is seeing how the app presents the St Augustine Inlet and the junction with the ICW at the inlet. The NOAA chart is fairly useless, whereas the Sonar Chart is very accurate. I use this inlet a few times a year and am somewhat familiar with it. Most recently 2 months ago. Aqua Map shows depths consistent with my experience and Navionics.

NOTE- in Aqua Map, it is a separate download to pull the USCG data, specifically the buoys!! If one does not turn in that feature, the data does not present on the chart. That is a HUGE issue.

I have tested a few apps that try to do it all. I am yet to use one that does all the functions well. There are some full blown programs that are pretty good, but no apps.


For weather Predict Wind PRO is the standard that others should be measured by. As a delivery guy it is worth my $500/year.

For coastal sailing, or short hops, look at Luck Grib. Purchasing the basic package will allow you to start to really learn how to use and read a GRIB. Add the routing module and you are on your way to fully understanding how to use weather to your advantage.

I’m not sure that needing to turn on the various options in AquaMaps is a huge issue. ANY navigation app needs to be configured or set up prior to use, just as any mapping program needs up to date charts.

I DO find the need to update charts and USACE surveys manually to be a flaw, but I have gotten into the habit of updating Navionics and AquaMaps the night before we haul anchor to get the most up to date information.

Don’t misunderstand me, it is not an issue to turn it on. But (call me old school) buoys are an essential part of navigating and therefore an essential item to display. Defaulting them to off it foolish. Buoys should default to on. Hence my “Note” comment.

This is one of the reasons I prefer SEAiq. If they and iSailor merged they'd have potential to easily be the best nav app. (Assuming they combined SEAiq's functionality with iSailor's UI/UX and not the reverse!)

It also lets you add a ton of chart annotations. I'm not talking about the "drop a marker here and attach a note" type in other apps, the sort you can easily miss, I mean "draw a polygon around the area you want to mark and color it in" sort. You can drop as many VRMs or EBLs as you like, and even attach them to AIS targets.

(The downside is ease of chart availability; it's really only the NOAA charts that are hassle-free, and as mentioned they can be a bit lacking in some places.)
