Thanks.  Can you get the B&G to display MWA?

In short, not on the instruments.  You wouldn't want to in any case as it's undamped.  You can display it on the B&G Web interface alongside AWA but for useful comparison it's best to log AWA and MWA using Expedition and/or stripchart,  and analyse the data post-fact.

Post race you can look at the log file, using strip chart to help and then use Expedition tests to extract the relevant data for comparison.  A very useful way to see if your cals are working  but beware, AWS being another component of the wind triangle you also need to compare that with the raw data to check tour TWS calibrations.  Leeway important as well.

And if you're using Expedition logging, you need to use the websocket connection not Hlink.  The raw data isn't available over HLink for some reason.




 

FFS Duncan!  Just send Hayden down there with a tape measure next time he cleans the bottom...  Record what time it was, then cross reference to the Sydney Ports actual tide data (incorporates atmospheric variation), barometric pressure on the day and crunch the numbers.  You're all of 800 metres from the official tide station so scope for error is limited...

I'm pretty sure you're overthinking this.

I'm wrestling with the same thing.

BTW, I don't get the AIS traffic to Expedition either.SparaSpara

I do, but it comes in via a seperate NMEA interface to the PC.
 

Well you could have called and asked...

There's a setting someplace in Exp (under Instruments IIRC) that you can switch on to send range and bearing through to B&G - it uses one of those "#OV..." type commands to display the data on the H5000, but if there's a plotter also connected to the H5000 system with a mark range and bearing set in its little brain then it will also send that same command to the H5000 processor and the two data streams will be displayed in parallel on H5000-connected displays, typically alternating - depending on their respective update frequencies.  Now assuming both the plotter and Exp happen to be pointed to the exact same waypoint this isn't an issue, but if not...well things get a bit silly.  Especially when waypoint pass / progression criteria in the two systems are set differently or one gets changed manually and the other don't.

Without having Exp in front of me I think you could also assign these variables to Expedition Alternating channels and then send these to a couple of "External" channels on B&G without overwriting the plotter output.  But then you've got two seperate sets of Range and Bearing data in H5000 and confusion will reign...

An Expedition Alternating function can also be configured to display different data based on point of sail and in pre-start and post start.  It's in the manual.

Net net if you're using Exp for Range and Bearing don't use the plotter ...  then you're short of immediate backup if the PC explodes but you can usually get the plotter working pretty quickly.
 

That drift is way bigger than I'm used to seeing.  I use two GPS on my good ship, one is a USB puck the other the on-board Raymarine unit.  Something defs amiss in your plot.  If you want to borrow my puck for a third opinion let me know!
