I run a VPN connector (OpenVPN Cloudconnexa) into my boat to allow me to be able to connect my iPad to the NMEA data that I have piped into my boat network. Once I am connected to the VPN tied to my boat I can pull all of the data on the NMEA into my TimeZero app and show the position of the boat, heading, speed, and water depth it is operating in.
Note, I do not have Starlink on my boat, just T-Mobile home internet so this only works when I am in range of cell towers. I see no reason why this setup wouldn't work with any other service provider. I use a connector inside of my network because T-Mobile uses a double NAT. Not sure about Starlink, but I image that they are probably doing something similar.
I have the $250 roam priority plan that works further offshore than 12 miles. It’s the only plan I’ve found that guarantees I have service when I head out to sea. Some folks try to change plan before heading out and it says not currently available due to subscriber limits. Haven’t been willing to take a chance yet but if you actually try your plan above and it works please let us know.Thanks again. You are correct, tracking of our voyages by anyone ashore (with access). Location sharing on the phone is a great idea, but I think I'd view that as a backup. I REALLY like the Garmin InReach/Messenger feature and have a good ~10 years of history on their map for every trip that I logged. Might just be easier to keep this.
I read the PDF Johnny posted above and it looks like that Fleet Tracking requires TZ Professional which I suspect is another license/added cost. I'm trying to reduce my monthly subscriptions to help offset the cost of Starlink (if possible and no increased safety risk).
Do you have any details about how you use your VPN? I can "stream" N2K navigation info to my iPad/TZ iBoat already via my Cortex so i'm not clear what the VPN gives you that's different than that? What I'm not clear on is how that would push to the cloud (via Starlink) and then be accessible from a home base TZ iBoat app. My iPad is WiFi only so that's a limiting factor.
Regarding Starlink subscription....that's another confusing topic. Most of my boating/fishing is out and back to the canyons so no real cruising. Plus, the boat is behind my house and can access my home WiFi while at the dock so I need limited bandwidth. Current thinking is I'll get the Roam plan advertised at $80/month for 50gb. This will work up to about ~12nm off shore and I'll need to flip over to a pay-as-you-go plan to get off-shore coverage. This is $2/gb. Hard to imagine that we'll burn a significant amount of data while on a fishing trip so that nominal amount should be a rounding error. All that said, I'm told that after you register, new plans are unlocked and pricing could be $50/month for the 50gb. Unlimited plans are something like $256/mo.
