A mistake in identity?

I have two c. 1944 advertisements in my collection – both featuring a Type 327 ST tug, built for the US Army, one from Enterprise, and the other from Busch-Sulzer.

You will note….both advertisements feature the same tug, ST-246! These 86′ Type (design) 327 tugs were built throughout WWII by numerous shipyards across the country and used 3 main types of propulsion, all of which were direct reversing engines:

Enterprise Engine & Foundry Co. – DMG-38: 8 cylinder, 12″ x 15″, 650HP
Busch-Sulzer – 6DFMT-17: 6 cylinder, 13″ x 17″, 650HP
Clark Brothers – MD-6: 6 cylinder, 12 /2″ x 16″, 650HP

It is likely that both of these companies used a stock photo provided by the Army, however it is indeed good for a laugh. A good portion of these tugs went on to postwar careers, many of which would get EMD 567ATL repowers. The Great Lakes region is home to a handful of these, as well as some with original Enterprise engines. The Enterprise seems to have been the better choice of the three. Other classes of ST tugs built during WWII featured a swath of other engine makes, including EMD, Atlas Imperial, Cat, Superior-National, Buda, Kahlenberg, Fairbanks-Morse and others.

According to Dan Friend’s roster – the 246 had the Enterprise (and may still be around!) – https://www.usarmysttugs.com/uploads/3/3/1/4/3314314/ww2_st_st_9_-_937__9_26_2014.pdf

Sarter Marine Towings Susan L (ST-709) is still powered by her original Enterprise DMG-38, and is likely one of the only direct reversing tugs still working commercially.

Old Advertising X – Nordberg Radials

One of the coolest engines made – the Nordberg Radial. The engine, a 14″x16″ was offered in both 11 and 12 cylinder models, in spark ignition gas, Diesel, and Dual fuel options. I would love to find a manual for one of these!

I don’t foresee doing any articles on these engines as they are well covered on the web. Be sure to check out these pages for more on these engines:

Old Advertising II

This week, we feature a prominent local shipyard – Jakobson Shipbuilding, in Oyster Bay, New York. Jakobson (originally Jakobson & Peterson, located in Brooklyn), moved out to Long Island in 1938, and would become very well known for their quality, and typically overbuilt vessels, especially tugboats.

Jakobson would overtime work very closely with TAMS Inc. Naval Architects, Merritt Demarest, Marine Design Inc. (Joe and Al Hack), Cleveland Diesel, EMD, Moran Towing and many others.

“Southern Kraft #9” was designed by Merritt Demarast, and used for moving pulpwood barges in South Carolina. She was covered in the April 1955 issue of Diesel Times, the Cleveland Diesel newsletter.

Jakobson (very often misspelled Jacobson) would keep busy right until the late 1980’s led by George Hossfeld. Jakobson Shipyard’s last new construction was the tug was the “Consort”, built for Express Marine in 1984.

“Julia C. Moran” (and sister “Eugene F. Moran”), designed by Joe Hack, then working at TAMS Inc., was one of the few new tugs that did not last long at Moran. She was sold to Venezuela by the mid 1950’s and renamed the “Puerto Ordaz”. Moran would replace the tug with the former Lehigh Valley tug “Wilkes Barre”, a nearly identical boat, which they also named “Julia C. Moran”. This has created much confusion for historians over the years. Note that Jakobson is misspelled on the ad.

Ultimately, the yard would be sold to Moran Towing, who used it as their personal shipyard, as well as doing other outside work using their marine railways, and a single small drydock. The yard closed in 1993, and the property sold to the town in 1997, where it is now a park. Very little remains of the original yard.
