I have not used it, but the ad sez in the FAQ:

=smallNomad has a USB interface (for power and data) that can connect to a PC or MAC.  Any AIS compatible navigation software can be used and the PC will create a virtual com port.  Digital Yacht offer free SmarterTrack Lite viewing software as well as premium SmarterTrack software for use with Navionics charts for detailed charting and navigation.  It’s also compatible with popular programs like MaxSea, Nobeltec, =smallExpedition, SeaPro and Open CPN.  Most modern programs accept a TCP/IP or UDP feed via the wireless link, but do double check before purchasing.

Not cheap though!  Their contacts show email and phone contacts in both UK and US
Maybe someone will chime in who has tried on.
Cheers,
Ernie

Not sure what you want to do but you can edit or change the start marks like any other marks in the tab Marks/Edit Marks/Start as well as the special features in the tab Start

It is the distance from the boat to the mark before the active mark and the distances between all marks before that.

So in order to compare Tracking numbers, all boats would have to be on the same leg. heading for the same active mark?

Joe,
I ran up some numbers on fastnet2019 this morning and they work ok. I wanted to make sure they were from the first mark of the route vs a set mark starting line or something.  I could slide the unlocked 1st mark around and effect the DFS number.

But I will say I have had problems before when working from the home pc tracking various Bermuda runs and getting DFS #'s of multiples of the actual DFS so make sure they pass the 'makes sense' test.
If you find some detail relating to those kinds of errors let me know.
Cheers,
Ernie

Kass,
You can do that using "Instrument" feature on the Optimize tab and readjusting your Settings to "use Instrument winds" 

Another method, I like better, is to find the tide point at the time of your class start of your race.
Say it's '1 hour after flood at Point Rump'
Find that tide point for every day from now until the actual Start
Every day until the race, use the time that corresponds to  '1 hour after flood at Point Rump' as your start; with 'real' wind.

You will get a variety of wind conditions but with close to the actual tides for your race
AND you can run all the fabulous features built into the Expedition Optimize tab; like 'TWS%' and 'TWD+/-'

Good Luck in the Fastnet!
Ernie

Try clicking 0n one of the 1-6 numbers say '1' ; then click on SettingsOn the right hand side of the settings window that opens, there is a list of WX featuresClick on the '+' next to 'Wind 10m;you will see a list of ways to display “Wind:”e.g. the item “Arrows” has a drop down list to the right which allows you to select; None, Barbs, arrows, scaled arrows, etcOnce you've made your selection you can click OK and you can see the results on the chartThe best way to learn all the features is to tweak them and see the resultYou might want 1 for Wind a certain way on a  local chart but want to use another number when working offshore with Gulf Stream Currents made prominent, another featuring Rain etc. Some of the features may overlap so having a separate 'state' helps you see them.Cheers,
Ernie

Can you leave 'avoid,,,land" unchecked and use tab Sail/Race Notes to keep the route off the dirt?
