Re: AIS through satellites.

I’m going to finish my tea then launch the asym, the wind has dropped.

Re: AIS through satellites.

We’ve sailed out of range of Wirrina and are now covered by Hallet Cove. Only 23 miles to go.218664

Re: AIS through satellites.

Well, we won’t do the same. We stopped to sleep for two hours, playing a juggling act on the tides. I didn’t want to do the channel at low tide, and I wanted cross Backstairs at slack water, thanks...

Re: AIS through satellites.

Thank you for spottong that, I would have missed it and I would have remained worried!
It can't be coincidence. We appeared on satellite within minutes of leaving American River. It must be...

Re: AIS through satellites.

That’s two more than the Gulf St Vincent at the moment. Which means everyone else was smarter than us.

Going to try and make a run for it tonight, around midnight. Fingers crossed we will reappear...

AIS through satellites.

So... just to be clear, you see an unidentified sailing boat south of Walpole? Right?

And yeah, 15 meters x 3 meters is more likely.

Which reminds me... I’ve been meaning to let zenith_adelaide...

AIS through satellites.

Ummmm... are you still on the free trial of satellite data? Because I only see a generic unknown yacht off Walpole.

Either way, that’s an impressive trip in a 5 meter boat!

AIS through satellites.

Meanwhile, it appears our neighbour, Caspian Harmony, set sail this morning. And a quick look at Marine Traffic suggests a number of boats had delayed their transit of the Great Australian Bight for...

Re: AIS through satellites.

Happy to say it is not an issue here in South Australia. I was a little worried about how the island locals would respond to us but I didn't need to be.

Re: AIS through satellites.

Yes, you are right about the power and frequency bit, however the unknown vessel bit is about whether or not you choose to pay Marine Traffic for their satellite data service.

In my case I am...

Re: AIS through satellites.

Yep, I won’t argue. Ballast Head royally sucks right now. Still stuck here with wind, rain and monster waves between us and home. Delayed by five days now.

Re: AIS through satellites.

I have the Matsutec, which is a bit of an unknown.

But I do know it outperforms a number of boats I know first hand, including boats with the highly regarded Vesper 800. I have a simple...

Re: AIS through satellites.

Yes, your guess is correct, and Mr Cromwell caused a few grey hairs this morning because I had forgotten to turn off my AIS proximity and TCPA alarms.

I thought we’d broken free of the mooring...

Re: AIS through satellites.

Ah yes, there’s some stinking weather coming through, now that you mention it.

I had checked their port of origin... what a forlorn place. And yes, what a long passage.

Not much I can do about...

Re: AIS through satellites.

Bugger!

I think we may have sunk during the night. NOTHING is working this morning. Bl—dy HF is on the fritz, now it seems AIS has gone toes up as well.

Actually, this is weird. I can see...

Re: AIS through satellites.

Are you out of pea soup as well?! I had no idea the situation was so dire in Victoria. Perhaps I shall share some of my hoard in the keel, I think I have around 400 cans... or was that rolls...?

Re: AIS through satellites.

Thanks for that question, I just spent an hour on Wikipedia when I should have been studying. But if I were a guessing man I’d say they might be using the Canadian based exactEarth network. That...

Re: AIS through satellites.

I was thinking along similar lines, but also wondered if there was some back end processing required for boats that first appear to satellites without corresponding land signals.

Gotta love an El-Ping stream of conscience.

Yep, good point about ballast head, and when I thought about it a bit, I remembered that I was often surprised by the delay in boats showing up down...

Re: AIS through satellites.

See my costs remark, but if I were really serious, yes, I’d look into some of these options.

As it is, marine traffic is good enough. Anyone who knows me and is likely to be interested in my...

Re: AIS through satellites.

And that’s where I am a little concerned. I’ve observed that behaviour and I’d moderate their description to say it seems to be around six to eight hours on average around the south eastern...
