Sorry 'bout that... "Random Generated Group". They're the little yellow boxes in the picture above, from the US_HarborTraffic file. The green ones are the regular ships, already chosen, with a set time, from the US_NavalBases file. RGG can have a spawning percentage as a group, and with the individual ships in the group. btw, you can't directly "set" the time of departure for your boat.
