  1. I LOVED this! Thank you so much for all your hard work! It is so much fun checking on everything going on in Duluth from here in Southern California.

  3. Goodbye Middletown. Legendary boat.
    Wow, she almost strapped the wall. I realize tows are tricky but was there a current coming through the canal today? Both the Victory and the Spirit took some weird approaches on the turn.

  4. I see what people were talking about strong currents possibly effecting the American Spirit. The Victory came close to scraping the side of the canal as it came out,
    Very nice video

  7. T3's were built in

    Chiwawa-class 7,700 horsepower two-cylinder engine single screw.
    Cimarron class 13,500 horsepower, two, two cylinder engines twin screws.
    Ashtabula-class 30,400 horsepower, two, two cylinder engines twin screws.

    So my first watch on Middletown - American Victory I climb the ladder to the boiler room. I notice there were four periscopes versus the usual two. Periscopes were installed on all steam boilers. Periscopes allow the fireman to "see" the products of combustion output from each boiler furnace. The goal was a light brown haze known as Economy Haze since this meant the proper fuel oil to combustion air ratios. However port regulations require a clear stack at all times while in port so excess combustion air was used.

    The periscopes were made of lengths of four-inch pipe with an adjustable mirror installed in a square housing at each 90-degree turn. At the outlet of the furnace the periscope is mounted on one side of the uptake. While opposite it on the other side of the uptake was a large 150-300 watts light blue tinted light bulb producing a white light. It was easy to recognize a clear stack while Economy Haze caused the light to change to a yellow cast. Of course smoking heavily -- such as when blowing tubes -- caused the periscope to black out.

    The Middletown had a pair of US Navy "M" Type, two furnace steam boilers. All other steam ships I sailed had a pair of single furnace boilers. Single Furnace boilers had the Super Heater tube bank mounted above or alongside the Saturated Steam generating tubes. The ratio of Saturated Steam to Super Heater steam temperatures were selected when the boiler was designed. Single Furnace 450-psig steam boilers Saturated Steam outlet temperature was about 460 degrees Fahrenheit, while Superheated Steam outlet 430-psig and 750 degrees F.

    Two furnace "M" type boilers allow operators to adjust the temperature of the Super Heater Tube bank separate from that of the Saturated Steam. Saturated steam is run through Super Heater tubes to raise its temperature in so doing also reduces its moisture content. Steam Turbines were designed to operate best at specific pressures and temperatures.

    The Middletown "M" type boilers were installed facing each other with a forward Super Heater Furnace and an aft Saturated Steam furnace. The steam water drums installed athwartship faced each other across the boiler room plates. There were four periscopes one on each of the four furnace uptakes.

    In WW II most US Navy Destroyer's and larger ships had either "M" type boilers or "D" type boilers. The below shows the "M" type boilers on

    These boilers are larger than those installed on Middletown-American Victory.

    The Chiwawa-class Middletown-American Victory 7,700 horsepower double reduction geared two-cylinder steam turbines were directly connected via shafting to the propeller.

  8. Would those tugs actually take her across the ocean is there something larger waiting down the line?
