As Nick explained you need to open both log files in Excel.
Edit:  replace the "boat number" from the second log file from "0" to e.g. "1".

Then copy/past the rows of the second log file underneath the rows of the first log file.   Then sort this combined worksheet on the "UTC" column "oldest to newest".   This ensures that the logging rows of the 2 boats are sorted on time (this is very important as Exp needs all rows in the logfile in "oldest to newest" order).
Then save this file as .csv again.   

Now you have a single log file that contains the data of the two boats.  This logfile you can open in stripchart and then you are able for each variable that you want to display to identify if you want it for boat 0 or boat 1 etc.
Now I think about it:  likely if you open this logfile in Exp (on the Tools menu) it will also display the two tracks of both boats? (I cannot try that now as I dont have Exp at hand).

Duncan,
Afaik you can only display 1 track.
However, in stripchart you can indicate for which boat you want to see each variable for which you display a chart.  So you can e.g. make a chart displaying TWA for boat 0 and TWA for boat 1.  When you then set wands you can compare the two TWA's.

That's indeed a much better and simpler way of doing it Nick!

if you have 2 log files (e.g. from different boats) for which you want to compare e.g. TWS or TWA,   what you could do is the following:
Open both log files in Excel and in one of the Excel files you replace the columns that Expedition has logged for AWS and AWA with the data of TWS and TWA of the other log file.    When you then save the file as CSV again you will be able to compare the TWS/TWA of the two boats by creating a Stripchart that displays TWS, TWA, AWS and AWA,  knowing that un fact the AWS/AWA traces are the TWS/TWA of the other boat.

However, be careful that the data line of the two log files are synced in time when you insert the data.   Ensure both log files have the same logging frequency (e.g. 1 Hz) and that you then copy the correct lines so you indeed compare data from the same moment in time.

Duncan,
The bug is solved in 10.6.11 and setting an alarm at e.g.  LAT>33 15.144s now works perfectly.

You can just configure the alarm and close the window.  The alarms gets triggered as soon as the condition is met.  You can link e.g. a sound file to the alarm to get an audiable warning.

The simulator is on the Playback ribbon.
But you seem to be right:  when I try to set an alarm on e.g. 33 15.144s this gets reset to 33 00.00n as soon as you close the settings window.

@Nick:  this seems like a bug.

I just tested option 2 with the simulator and the alarm worked fine for me.
I had my boat sailing west and had the alarm set when LON < 005 00.000e
As soon as the boat passed that mark the alarm sounded and a pop up window appeared.

I would mark the shipping channel with a race note (NOT to be avoided by optimal routing).
Then configure an alarm in Exp that is triggered when the Time or Distance to race note channel falls below a certain value.
In case your route passes multiple race notes this alarm may also get triggered for those race notes where you don't want it to be triggered, but otherwise it is the best option I can think of.

Another option would be to set an alarm when LON or LAT passes a certain value but this would be harder to configure and not works as well depending on the orientation of the shipping channel in relation to your course.

In the utmost left top corner from the expedition window click on the drop down arrow.  Than choose "exp data folder". In that data folder there is sub folder called "log".
