Have you ever seen these huge ships that regularly sail in and out of our harbor?

They have no portholes to speak of, and look like gargantuan floating boxes, their mysterious contents shrouded within.

They are called “Ro-Ro’s” by the industry… but why?

Ro-Ro’s are vehicle transport ships.

Vehicles, unlike other cargo, are not packed into shipping containers and loaded by gantry or transfer cranes. Instead the automobiles are driven right onto the ship and then off again, once they reach their port of destination.

“Ro-Ro” is short for “roll-on, roll-off”, a descriptive term used to describe car carrying cargo vessels. Loading and unloading vehicles in this way is very effective in getting the gigantic carriers in and out of port quickly and efficiently.

I wonder how many Ro-Ro’s cruise in and our of our port daily. I never fail to see at least one every time I am out on the water.

And to all who celebrate, a very Happy Easter and Passover to you and your loved ones!
