I am working on this "Anchor" gauge. Mainly for the watch and iOS Widgets.

I plan on adding the track (which I have not wrapped my head around)
That's distance from anchor in the top left
What other info would you want to see
I was thinking I could show wind angle as an arrow around the alarm circle
I happen to be at anchor with good wind, but the arrow pointing at the "circle a", is the boat. It moves around.
the arrow is the boat heading? presumably.
yes showing wind is useful..
im also thinking aloud about “leeway” and if its useful to be able to show?
eg i often anchor in some rivers/estuaries that have strong (tidal) currents, (1-2kts) & hence over a period of time,
the boat swings 180 degrees based on tide flow in/out… and of course mix in wind, (with a big arse flyybridge) and you get some weird behaviour whilst at anchor..
eg often the boat is not pointing at the anchor .. and its useful to understand the influences..
Right now, the arrow is just pointing at the anchor. But I will make it the heading.
Is “leeway” actually calculated properly by anything?
Maybe it would more interesting to show the general direction the boat is moving in?
So COG
that was what i was trying to wrap my mind around…
effectibely the “leeway” is generated by the STW ..
probably more correct to call it “set and drift” in thisninstance.
Not accurate in my experience
eg assume the boat is “stationary? the STW is showing the tidal current ..(with some. vector math i guess) .
still thinking it thru
even showing STW woild be part of the answer
Yeah. That’s why I was thinking COG.
Isn’t that what really matters!
COG would be part of answer.. but it coild still be =0, and there could be current actions
Agreed
influence from current movement i meant
im gonna have another coffeee and wrap my mind around this one …
🙂 having trouble keeping pace with test flight updates 🙂 haha. now multiples per day
Working with some Watch owners and Victron VRM users. Getting great feedback!
.. almost makes me want to run out and buy an apple watch 🙂
I am now a convert
I wish my eyes were better though
getting old (er) is a shit .. i agree
Getting younger would really suck
I've ended up with a similar display and do have a track working, so this might help. Although just revisiting the code it's not particularly nice and I'm missing comments explaining what's being done☹️ https://github.com/philseeley/boatinstrument/blob/d04e638cea1d021d1fd14c7bd2bf253f925db125/lib/widgets/anchor_box.dart
