Nothing happens now, because Paul is on the road.
Try following: Go back to sea a few miles, choose course to a Lake Gatun, and set constant speed.
In the navigation chart double click Lake Gatun, where you want to take over your ships control, and note the time to get there.
Then close Ships2 simulation properly, and wait until this time has elapsed.
The Channel Pilots will take care of your ship during this time.
Login to the simulation again, and continue your journey.
You will certainly have to do this a couple of times during journey.
