Patriot State was the training ship of the Massachusetts Maritime Academy from 1986 to 1998.
Massachusetts Maritime Academy’s training vessel, the Patriot State, came came to the academy in 1985. She is the latest in a line of training vessels stretching back to to the Enterprise in 1893.
The Patriot State, originally named Santa Mercedes, was built in 1965 as a single screw cargo passenger vessel for Grace Line, Inc. The design is a C4-S1-49a. The vessel was built at the Sparrows Point Shipyard of Bethlehem Steel Company at Baltimore, Maryland.
The Santa Magdalena, the first of the class, was delivered to Grace Line on February 4, 1965. She was the first of four cargo-passenger ships of remarkably modern and progressive design.
The sister vessels included the Santa Mariana, Santa Maria, Santa Mercedes and were destined to play an important role in promoting closer ties within the Americas, carrying passengers and cargo between Atlantic Coast ports in the United States and the Canal Zone, Columbia, Ecuador, and Peru. The ships were designed by George G. Sharp Co., naval architects and engineers of New York.
The ship is of welded steel construction, full scantling type, single screw, machinery amidships, with raked stem and modified cruiser stern. The main hull is subdivided by seven watertight transverse bulkheads with three holds forward and two holds aft of the machinery space. The vessel meets the Maritime Administration requirements for a two-compartment ship. There are three complete decks in the hull, with platforms and deep tank tops at various levels. The A, Promenade, Sun and Bridge Decks and the house top form the midship house, which extends for approximately one-third of the ship’s length.
The vessel is single screw with geared turbine propelling machinery located in the machinery space amidships. The steam cycle employed uses a high-efficiency, cross-compound turbine, four stages of regenerative feed heating, and high-efficiency boilers fitted with rotary regenerative air heaters. This basic cycle arrangement is one which has demonstrated satisfactory performance and reliability on a number of American ships, such as the Barrett Class MSTS transports (Bay State, Empire State and State of Maine.)

From the beginning, the Grace Line management desired, as the major design objective, to achieve increased efficiency by lowering cargo handling time and costs. An operations analysis of the trade route was made by Sharp to determine the characteristics of the cargo moving on the route and to establish the feasibility of mechanical handling of cargo in units. This operations analysis included a detail study of the cargo commodities transported on the route and included analyses of weight, dimensions, net cubic, gross cubic, port of origin, port of destination and a classification of the cargo concerning its susceptibility to unitization. Trends in cargo carryings were analyzed and, in conjunction with trade forecasts prepared by Grace economists, were projected into the future. The port conditions, which would have an effect upon the design of the cargo-handling system and the ship, also received careful attention.
The southbound cargo was generally manufactured goods of approximately the following composition:
Percent by | ||
Volume | Weight | |
Bagged and packaged cargo suitable for containers or pallets | 41.5 | 44.8 |
Machinery, knocked-down automobile units, drums, newsprint, etc., having dimensions less than that of a container |
22.7 | 30.1 |
Vehicles smaller than container size | 15.8 | 3.5 |
Vehicles and machinery larger than container size | 9.8 | 6.2 |
Steel pipe, rails, etc. less than 35 feet in length | 4.5 | 8.2 |
Steel pipe, rails, etc., exceeding 35 feet in length | 0.7 | 3.6 |
Large items | 3.7 | 2.2 |
Lifts over 20 tons | 1.3 | 1.4 |
Total: | 100.0% | 100.0% |
The northbound cargo had different characteristics, and it was obvious from a review of the commodity listings and packaging data that practically all could be handled by unitized and bulk-handling systems. This cargo included a large amount of bananas and other refrigerated cargo.
Comparisons of the cargo moving in each direction were made to select the proportion of space to be adapted for containers, pallets, trays, bananas, etc. Analyses were made of year-to-year and voyage-to-voyage variations to determine the flexibility required.
With information thus developed on the characteristics of the cargo, preliminary studies were made of various ship arrangements and systems for handling and stowing of the cargo. The results of these studies indicated the desirability of providing the following:
The integration of these requirements, along with the requirements for passengers and public spaces, led to the design of the Santa Magdalena and her sister ships containing the most varied and the most modern mechanical cargo-handling systems to be incorporated in any ship. The systems include large overhead cranes for containers, sideporters, horizontal and vertical conveyors and elevators, each designed to perform a different cargo-handling function, but all systems to work together as a simple complex.
The Santa Mercedes was obtained by the Maritime Administration in the spring of 1984 for conversion to a training ship for the Massachusetts Maritime Academy. Conversion was accomplished in two phases. The activation phase, including changing the ship’s name, was accomplished by the Triple A Shipyard in San Francisco. The vessel was then towed to Bender Shipyard, Mobile, Alabama for the conversion phase. On 7 September 1985, the Patriot State was turned over to the Academy.
The following year, four hold was opened up for use by installing the stair tower, fire stations, and a watertight door to provide access to the B-deck cross passageway. The facilities in four hold, including the machine shop, maintenance training lab, classrooms, spare parts storage, and gym were all constructed by cadets. In 1993 an extensive upgrade of cadet berthing facilities was begun with the installation of heads, showers, lockers and bunks in three hold D-Deck.
Provision was made for carrying bananas or palletized cargo in holds 1, 3 and 4, and carrying of containers in holds 2 and 5, and in one cell group in holds 3 and 4. Automobiles could be carried in holds 3 and 4.
The bananas were loaded through sideports, manually or by horizontal conveyors, to the top of vertical conveyors by which they were transferred to the lower ‘tween decks where they were discharged and stowed manually. Bananas were discharged by manual loading at each deck into the vertical conveyors and by automatic discharge at B Deck on to short transfer conveyors, thence on to horizontal conveyors through the sideports to the dock.
The containers stowed in holds 2 and 5, in portions of holds 3 and 4, and on deck, were handled by four “C” type gantry cranes. Basically the ship was designed for 20-ft. standard containers (9’-10 1/2” long) and either 8 or 8 1/2-ft. in height. In addition, the inboard cells in holds 2 and 5 were arranged for ready adjustment for the stowage of 40-ft. containers alternatively to the 20-ft. containers. Also deck stowage was provided for 17, 20 and 40-ft. containers. The container capacity was as follows:
Four 20-ton capacity deck cranes were provided, two forward and two aft, to handle the containers in holds Nos. 2, 3, 4 and 5 and on the main deck forward and aft. The cranes were of the traveling gantry type, running on crane rails located port and starboard near the ship’s side.
The gantry cranes were of the “C” type having one open end which permits marrying of two cranes to handle large vans. Another novel feature in the crane design was a counterbalancing arrangement whereby the machinery trolley moves in the opposite direction to the load trolley so that in the empty condition, the crane was essentially counterbalanced.
The sideports, gantry cranes and the vertical conveyors were removed during the conversion to training ship use. Remnents of the vertical conveyers and sideports can still be seen in four hold.
