New here. Got great help with my first question. Hope this might be helpful to the next person.
1. Download raster charts
2. Open MapcalII utility. This is a seperate program from Seaclear. You will find it in your Start menu.
3. (IN Mapcal) Tools--Set Directories.
4. (Mapcal) Assign the path to the file you just downloaded.
5. (Mapcal) Click OK.
6. (Mapcal) Tools-->Autoload list-->scan for new charts
7. (Mapcal) Tools-->Autoload List-->recreate.
8. Close Mapcal.
9. Restart Seaclear (if it was open while using Mapcal).
10. (In Seaclear) File-->chart-->list all.
You should see the chart(s) you just installed.
