A rowboat was paddled out to meet our ship. It carried a light throwing rope that was thrown accurately to Panama Canal workers on our ship who used that light throwing rope to pull the heavy steel cable over from the mule.

The row boat returned to the dock that extended out into Miraflores lake. Notice that the man was just climbing a ladder back up onto dock.

One of the Panama Canal workers leaned against a bent railing and watched our ship enter the Miraflores Locks.

The lock doors on the first of two Miraflores Locks were just closing behind a ship in the locks on the other side opposite our ship.

The lock gates of the Miraflores Locks were fully closed behind the United Milos ship.

The watertight gates were the ones nearest to the camera. An inner set was used to filter debris to prevent fouling of the main gates.

A mule held the ship centered using steel cables. A tug boat was tied up separately to the wall of the lock.

The lock drained. Notice that the mule was no longer attached to the ship. It was detached because the ship was tied to the lock wall using lines. That way the mule could return for the next ship, and another mule would take its place.
