General Discussion » What Book for Expedition - H5000 Polar Generation & Calibration? » 6/19/2020 3:57 am

Just a follow up - I emailed Will Oxley and he sent me some additional resources.  I also purchased his Modern Race Navigation book on Kindle.  

An additional resource available from North U is the Expedition 101 webinar conducted by Peter Isler.  I found that since I purchased this last year I can still view it on my Android phone.  A more descriptive index for the webinar contents is pasted below for anyone interested.  Peter does a really good job explaining the details for each of these areas.

Thanks Sparky.  I just emailed Will to find out which of his books covers the desired topic.

Last year I took the North U Expedition 101 webinar by Peter Isler.  It was an excellent course that exposed me to a number of great features in Expedition and how to do some basic setup, routing and displaying Expedition data on my B&G displays.  

I am interested in going further using strip charts to improve polars and develop polars for my Code 0 since I don't have any for it.  I also want to improve / fine tune sensor calibration.

Is there a book or online resource recommended that covers these topics? I prefer to purchase something I can "keep" and refer to afterwards as a refresher.  Unfortunately the North U webinars only have a 1 year period where you can go back and review information in the course modules.

Thanks Nick.  I just did that.  Expedition seems to work fine but the deleted file name remains in the dialog box even after exiting and restarting the program. I don't think it has any adverse impact on the program.

Nick,

The Settings dialog box for XTides is a file chooser. If you delete the text and submit, the only options is "Open" or "Cancel". Neither button saves it with blank text.

Thanks Nick. 

I changed it to the US Model RI & MA and it shows more data points on the chart.  All the labels on the chart are in the format 0.XX.  Is this supposed to represent a factored maximum?  Some current arrows appear over land masses rather than the water bodies.  The screen shots below represent planning I'm doing for a pursuit race in Narragansett Bay on 7 June.  I know that currents may be up ~ 0.7 Kts @ 230 under the Mt. Hope Bridge at 11:06 local and agrees with the local current chart predictions.  My optimal route planning shows set and drift 246/0.0kts as shown in the third screen shot from OpenCPN.  The Mt. Hope Bridge is a mark of the course so a convenient location to look at tidal currents.

How do I clear the XTide file box on the Tides settings screen?  I put an entry in there to try and now I can't clear it.

I have been using OpenCPN in the past and like the tidal current model used for my local sailing area (Newport, RI and Narragansett Bay) better than the model that Expedition uses.  OpenCPN uses the XTide data in a folder labeled tcdata.  The files in this OpenCPN folder are HARMONIC, HARMONIC.IDX and a README.harmonics file.

The Expedition PDF help file states:
Xtides
Expedition can also use the GNU Xtide software distribution global tidal station database available at http://www.flaterco.com/xtide/index.html.
Download the harmonics.txt file (it may be zipped) and select it using the Xtide button. Be aware that the file contains a large number stations and physically reading it may slow Expedition, so you may
just want to copy the stations you are interested into your own file.
This option is provided merely for user convenience. While Expedition uses a significantly different technique of computing tides to Xtide, the results should be very similar.

I have downloaded harmonics-dwf-20191229-free.tar.xz and extracted the files harmonics-dwf-20191229-free.tcd, ChangeLog and COPYING.

I don't know what folder Expedition keeps the tidal current models and how I access the Xtide button referred to in the help file.

Questions:
1. Can I use the OpenCPN harmonincs files directly in Expedition? If so, how?
2. If not, how do I import and use the downloaded XTide harmonics file?

Networking Issues » H5000 update » 6/17/2019 7:29 am

I can confirm that this is still a Zeus 3 issue.  I have both a Zeus 3 and Raymarine e97 on the N2K network.  I am able to get waypoint navigation from Expedition data fine on the e97.  No joy with the Zeus 3 which has the V18.3 patch. 

Suggestions for new features and capabilities » ENC charts - keep scale when scrolling into a new chart area » 4/02/2019 4:24 am

+1 for the feature that Fredrik proposes. 

I'm not familiar with the IHO standards but just browsed through S-52 and identified paragraphs that may be applicable to the display requirements.  I'm sure Nick has a better working knowledge of these standards and may be able to find others that apply in the transition between charts at the boundary.

3.1.7 ENC scale; Graphical Index of ENCs by Navigational Purpose; Limit of HO data 
.1 ENC scale.
.2 Automatic overscale at a scale boundary.
.3 Graphical Index of ENCs by Navigational Purpose.
