Stus-List Re: Navionics

[Matt Wolford via CnC-List]

FWIW, I like Garmin and have for a long time, but I’m not happy with everything 
it does (like buying and phasing out Nexus instruments).

 

For the type of sailing I do, Navionics works fine.  By way of example, I was 
in a race that crossed Lake Erie recently.  The crossing was mostly downwind, 
and I was able to stand behind the wheel and keep an eye on whether I was on 
course using the red line that projects out.  It literally allows you to see 
exactly where you’re heading all the time (as opposed to cross track error, 
which tells you how far off the rhumb line you are).  When we approached Long 
Point, the updated Navionics chart showed me that the profile of the end of the 
peninsula had changed since June, which helped us round the point without 
running aground.  After rounding the point, we headed for a buoy eight miles 
away, and again I could put that red line on the buoy and know my course to the 
mark precisely.  This is how I typically use Navionics – as I said, for me it 
works great.  If I were sailing from New York to Bermuda or something, I’d 
probably want more sophisticated navigation equipment.

 

Also, although the basic Navionics functionality described above is easy, other 
functions are not intuitive.  I’ve received phone calls from a number of fellow 
boaters over the years asking “how do I work this thing.”  There is no 
Navionics for Dummies manual that I’m aware of.  It should come with a manual.

 

My two cents.

I have to say I have very limited Navionics usage under my belt. One 
thing that bugs me is that
courses are always given in True, which means there has to be some

Generally, I can't see my destination, for instance hitting an imaginary 
mark off Canso, then turning
on a Rhumb line to Halifax Harbour outer mark.  I can do the math it is 
just stupid that I can't just get it
off the navionics, or I can go down and read it off the raymarine chart 
plotter or my garmin chart plotter.

[Dennis C. via CnC-List]

My Nexus instrument system and Garmin chartplotter show me critical
navigation data such as:

VMG - velocity made good wind based
WCV - waypoint closure velocity
STR - course to steer adjusted for current and leeway
SOG - speed over ground
COG - course over ground.
SET - set
DRF - drift
BSP - boat speed through the water
True and apparent wind

However, I usually ignore all of those and monitor TIICB.  TIICB is the
most important reading on the boat.  Oh, what is TIICB?  Temperature in ice
box.

*/I expect they will add a symbal to, "make my vessel show as an AIS 
target on other plotters".  All the data is being tracked anyway./*


With the navionics app, this would require a constant data connection. 
Either satellite internet, or cell data service. This currently isn't a 
great solution when on the water, but i t may happen once a lot of 
people have sat service on their boat.


The beauty of AIS is that it is a universal standard.  Any Garmin 
solution would only work with their plotters and apps. Businesses don't 
like universal standards, they would rather lock you into their platform 
for a constant revenue stream.


*/My presumption was that precise was determined by GPS and standard was 
integrated based on the available cell phone towers, which is inherently 
less accurate./*


Incorrect. On android devices, "standard accuracy" is GPS. "Precise 
accuracy" is a combination of both cell towers AND GPS.


Tablets and phones have tiny, internal, GPS antennas. They often have a 
hard time to receive from enough satellites to get good accuracy. To get 
a better signal, you use an external antenna, which the Navionics app 
can receive via NMEA over wifi. We use a WiFi Bidirectional NMEA unit 
that we paid less than $100 for. It allows external GPS, Depth, and 
speed, to be sent via wifi to Navionics on our waterproof android tablet 
and our phones.


*/I suppose the higher cost for the charts on the Garmin plotter vs the 
low cost of the Navionics mobile app for an IPad or phone is because 
there are a lot more folks using the mobile devices than boaters keeping 
up to date charts in their chart plotters./*


/This has more to do with the market they are selling to. Navionics was 
designed to be a reasonably priced alternative to overpriced nav 
systems. Garmin bought them to remove them from competition.  Garmin 
would likely love to charge the Navionics app boaters (who are used to 
the cheap navionics price) the same as they charge the people who spend 
a pile of money on dedicated plotters and their overpriced charts. Over 
time I can see Garmin slowly increasing the  navionics app subscription 
price to better match their normal business model./


*/FWIW, I like Garmin and have for a long time, but I’m not happy with 
everything it does (like buying and phasing out Nexus instruments)./*


That is their whole business model. Buy out competitors or innovators. 
Garmin is mainly a hardware company, and wants to sell you their 
hardware and their charts at high prices. The worst thing that happened 
to Navionics, is them being bought by Garmin.


Another was when Garmin acquired Active Captain from Karen and Jeffery 
Siegel...taking crowd sourced data, that anyone could access, and 
turning it into a Garmin product https://panbo.com/?s=active+captain




One feature that is nice is the ability to use live depth finder data, 
to update charts. I assume it was developed as a way to acquire free 
crowd-sourced depth data, on lakes that are not, or rarely are, 
surveyed. Thank you to the original Navionics company for SonarCharts.


Back when Garmin and Navionics were separate companies... Navionics was 
making Garmin MFD compatible charts, have SonarChart ability.    Garmin 
intentionally patched their software so it wouldn't work.

[Matt Wolford via CnC-List]

I can't "see" my destinations, either.  Let's say I want to go from Erie to 
Detroit through the Pelee Passage.  Once I'm in the Lake, I head the boat in 
the general direction, and the red line projection on Navionics will tell me 
when I'm heading for the Passage (about 100 miles away).  Unless there's an 
obstruction in between, that's my course; and Navionics will show my position 
the entire way there.  I can get fancy and draw a route, but unless I need to 
be precisely on the rhumb line, who cares?  If you need to create an imaginary 
mark to round first, you find the location on the chart, put your finger on the 
screen, create a marker (waypoint), and head for that.  It really does simplify 
things for people like me who drive the whole time (no autopilot).

The functionality you like isn’t unique to Navionics, I think.

 

The red line you refer to sounds like a route. When I set up a route on my 
Garmin chart plotter, IPAD, or Active Captain I get a black line on the chart 
to follow. I also have set up a heading setting that shows the current heading 
of the boat (as opposed to the previous course track) as a separate line, with 
the length of that line determined in the settings. IIRC, I have my heading 
line set up for 1 or 2 miles (you can also set it for time, I think.) I have 
this heading line on all the time. I like it because it shows my proximity to 
potential obstructions, ATNs, and lets me know if I have wandered off the 
shortest route, and it also gives me an idea of when I will get to a point on 
my desired route, and how far ahead the next corner is.

Thanks, Rick.  The red line is not a route.  The red line is always visible and 
shows your projected course an unlimited distance ahead.  If I change course, 
the red line changes as well.  It’s like an on-screen laser pointer.  You point 
the boat in the general direction and adjust steering until the red line goes 
to where you want to go.  That’s your course.  Miss Connie from Romper Room 
could navigate a boat this way.

[Rick Brass via CnC-List]

I think I understand it now. The red line is always shown and infinite length, 
and it is based on boat heading adjusted by current - or more probably recent - 
set and drift. If your destination or the next turn is off the edge of the 
display, you zoom out to bring it onto the screen and steer to keep the boat 
moving to that desired point. And I presume you reduce detail, depth markers, 
etc. when you zoom out.

In the eastern NC area where I mostly sail, but also in Chesapeake Bay and 
along the ICW and coast going south, my target is usually in the 10 to 30 NM 
range in front of me. With the plotter and IPad I usually scroll over to the 
target, tap the screen, and then select "Go To". That puts a line on the chart 
display from my starting point to the destination. Then I can scroll back (or 
press stop scrolling on the menu) to recenter on the boat and see the nearby 
detail (depths around here are frequently 10 feet or less, and the ICW has a 
lot of twists and turns), see the boat position and heading in relation to the 
course line on the chart, and make steering and trim adjustments accordingly. 

I wonder if the displays would work the same on Active Captain, my IPad that I 
use on deliveries, or my laptop had I chosen the Navionics charts instead of 
Bluecharts when I bought my Garmin chart plotter?

Thanks, Rick.  The red line is not a route.  The red line is always visible and 
shows your projected course an unlimited distance ahead.  If I change course, 
the red line changes as well.  It’s like an on-screen laser pointer.  You 
point the boat in the general direction and adjust steering until the red line 
goes to where you want to go.  That’s your course.  Miss Connie from 
Romper Room could navigate a boat this way.

With Navionics that I use I can put in a final destination and have it plot a 
course using my boat configuration settings

I think I understand it now. The red line is always shown and infinite length, 
and it is based on boat heading adjusted by current - or more probably recent - 
set and drift. If your destination or the next turn is off the edge of the 
display, you zoom out to bring it onto the screen and steer to keep the boat 
moving to that desired point. And I presume you reduce detail, depth markers, 
etc. when you zoom out.



In the eastern NC area where I mostly sail, but also in Chesapeake Bay and 
along the ICW and coast going south, my target is usually in the 10 to 30 NM 
range in front of me. With the plotter and IPad I usually scroll over to the 
target, tap the screen, and then select "Go To". That puts a line on the chart 
display from my starting point to the destination. Then I can scroll back (or 
press stop scrolling on the menu) to recenter on the boat and see the nearby 
detail (depths around here are frequently 10 feet or less, and the ICW has a 
lot of twists and turns), see the boat position and heading in relation to the 
course line on the chart, and make steering and trim adjustments accordingly.
