Non-Random Tugs 16

Twins today, but as with any twins, one will be deemed older. Do you know which?

Genesis Vigilant used to be called Michigan Service.  Launched in 1981, she’s 99′ x 34′ and propelled by 3000 hp.  The barge GM8001 is 348′ x 75′.

Years ago, i errorneously assumed she was an ATB.

This barge is slightly shorter, narrower and about a decade newer. 

GM 6506 is being towed by Genesis Victory, 

same dimensions as Vigilant and slightly newer, although still from 1981.  Genesis Victory used to be Huron Service.
