Hercules . .. built in 1915 in northeast Netherlands province of Groningen, served most of its career in Denmark as Fremad.  In 1978 she returned to the Netherlands and was was renamed as Hercules.  Back in November 2010, she set a record in Schiedam (see map at end of post)  towing 15 vessels,

a tow that measured about a half mile.

They traveled 2.6 miles in 35 minutes.

Here’s a shot somewhere in the middle of that tow of 15 vessels.

I’d love to have heard it.  All fotos compliments of Fred Trooster.
