If you go to the thread here Look Who’s in the Canal Today, and scroll back to post 155 you will see the bridgecam of NCL Gem, who was doing a partial transit. You can see how early she was approaching the canal. You have to subtract five hours from the time stamp on her cam as she was on GMT. When she is moving into the middle lock, with the red cargo ship facing her, you can see the black lighthouse. They have since moved that cam a bit. But her bridgecam shows good pics of the lighthouse, too. EM
