if you're a certain age you built this in one of its numerous boxings. I'm certain that this was originally an US Army tug, specifically an
82' 560hp diesel small tug. Many examples were built; I've seen the numbers range from ST-9 to ST-246. The as-built version is a bit more basic, but had a wrap-around forebridge not on the civilian version. Number nameboards on the bridgewings, U S ARMY on the stern, painted in OD or battleship gray. One way to get a US Army watercraft on the shelf.
