McAllister Towing is one of the oldest and largest marine towing and transportation companies in the United States. They operate a fleet of more than seventy tugboats and twelve barges along the East Coast from Portland, Maine to San Juan, Puerto Rico.

Although their corporate headquarters is located in New York City, they operate in the ports of Portland, Maine, Staten Island, New York, Philadelphia, Pennsylvania, Baltimore, Maryland, Hampton Roads, Virginia, Wilmington North Carolina, Georgetown, and Charleston, South Carolina and as Jacksonville, and Port Everglades, Florida, also San Juan Puerto Rico. McAllister engages in ship docking, general harbor towing, coastal towing, and bulk transportation.

Captain James McAllister started the first McAllister enterprise shortly after he arrived from Cushendall, County Antrim, Ireland. Together with his brothers and in-laws, McAllister formed the Greenpoint Lighterage Company. They augmented the lighterage business with towing, with the acquisition of their first steam tug, the R.W. Burke, in the 1880s, while the Brooklyn Bridge was still being built.

In the early twentieth century, there was a period of innovation and expansion. Captain James was one of the first to convert a sail lighter into a bulk oil carrier, for the transport of oil around New York Harbor. The company also became known nationally for its salvage work, which extended from the West Indies, along the Atlantic Coast as far north as Maine.

In 1909, the company acquired the Starin fleet of steamboat excursion vessels, forming the McAllister Steamboat Company, which was then among the largest excursion boat operators in New York, with regular runs to the Statue of Liberty, Bear Mountain, Coney Island, and Long Island. After the death of Captain James in 1916, his four sons assumed control of the company. The new partnership consisted of James, John E., Charles D. and William H., the second generation of McAllisters.

By 1918, the company had moved into the ocean towing business. McAllister inaugurated one of the first deep-sea tug-barge combination with the 156-foot long towboat C.W. Morse, carrying molasses from Cuba to New Orleans. Always an innovator, in 1927 McAllister installed a 375 horsepower diesel engine into the Daniel McAllister, making it the first diesel-powered tug in New York Harbor.

During the First World War, James McAllister served on the Board of Embarkation for the U.S. Government. He also held the post of Acting Director for the Army's floating equipment. Between the Wars, a fleet of twenty ocean-going tankers was operated by McAllister to all parts of the world for the U.S. Shipping Board.

With the death of James McAllister in 1936, the third generation of McAllisters assumed control of the company. Anthony, James, and Gerard McAllister are credited with maintaining the company's stability through the Great Depression. They also brought the company to its present-day prominence. During the 1940s and 1950s, the company expanded to include operations in Pennsylvania, Virginia, and Canada.

Today, those operations have expanded to include offices in Portland Maine, Baltimore Maryland, Wilmington North Carolina, Georgetown South Carolina, Charleston South Carolina, Jacksonville Florida, Port Everglades, Florida, and San Juan, Puerto Rico. In recent times McAllister helped pioneer the development of the Kort Nozzle, and Flanking Rudder steering systems aboard tugboats.

An Explanation of Professor A.A. Buhlmann's ZH-L16 Algorithm

by Paul Chapman

Note to new divers and potential new divers:

This information is presented for general interest. Don't be scared off by what you see here - you don't need to learn any of this to become a safe and competent scuba diver. You will however need to understand dive planning.

The following is a summary of the decompression algorithm described by Dr A.A. Buhlmann in the fourth edition of his book Tauchmedizin ( diving medicine ) published in 1995 ( only in German. ) the book contains a considerable amount of other information and is published by Springer-Verlag ISBN 3-540-58970-8. Rumor has it that at the time of writing ( November 1999 ) an English translation is being prepared for publishing, so hopefully, in due course, this document will become redundant.

The algorithm is simply a "recipe" for modeling the behavior of inert gases, which diffuse in and out of our body tissues when breathed under varying pressures. The intention is that if the recipe models the actual processes in our bodies accurately enough, it can be used to plan dives ( and other pressure exposures ) with a view to avoiding decompression sickness.
