Free Ship Plans of US Navy Cargo Vessel USNS Comet

U.S.N.S. Comet First Roll-on/Roll-off Cargo Vessel of Her Kind

C-3 Cargo Ship Had Stern Loading Ramp Allowing Vehicles to Load Under Their Own Power

FIRST DEEP-DRAFT OCEAN GOING CARGO VESSEL TO OFFER SELF-LOADING

C-3 Cargo Ship U.S.N.S. Comet

The first of her kind, U.S.N.S. Comet was designed for roll-on/-off loading of wheeled cargo such as military vehicles. Her keel was laid May 15, 1956. The ship was launched July 31, 1957, and delivered January 24, 1958.
U.S.N.S Comet was designed by the U.S. Navy Bureau of Ships and the Maritime Administration to carry fully-loaded self-propelled wheeled or tracked vehicles, and able to load and unload them through a ramp in her stern and four side loading ports. A series of internal ramps allowed the vehicles to be moved under their own power or towed into the holds.
Our U.S.N.S. Comet free ship plans page offers seven sheets of high-resolution downloadable plans perfect for the ship model builder looking for a challenging scratch-building project.

Free Ship Plans of Spanish Mine-laying Vessel

Spanish Navy Mine-laying Boat also Transported Torpedoes

Spanish name “Barcaza para Embarque y Fondeo de Minas y Transporte de Torpedoes”

Translates to “Barge for Shipment and Anchoring of Mines and Transport of Torpedoes”

Spanish Navy Mine-layer

This 1950s Spanish naval vessel was used to transport mines and torpedoes, and also worked as a mine-layer.
The smaller size of this boat would make it suitable for a larger scale ship model. The hard-chine hull would make scratch-building a model easier as well.

Free Ship Plans USS San Marcos, later Spanish Navy ship Galica

Launched too late for World War II action, Casa Grande-class Landing Ship Dock USS San Marcos had long history nevertheless. After a 26-year career in the U.S. Navy, she went on to end her career as Spanish Navy ship Galica, where she served until 1988.

USS San Marcos (LSD-25) was a Casa Grande-class Landing Ship – Dock of the United States Navy, named for the Castillo de San Marcos, the oldest masonry fort still standing in the United States.

An unusual subject, these free ship plans of USS San Marcos would be a great project for a ship model builder interested in either warships or cargo ships.

Free Ship Plan: Algerian Xebec Two-fer

Xebec with lateen sails

Not much put more fear in the heart of a Mediterranean seafarer than the triangular sails of a Barbary corsair appearing on the horizon.
The favorite vessel of these North African pirates was the xebec, a long, narrow ship descended from the rowed galleys of the ancient world. Able to sail close to the wind with its lateen sails - or to use oars if the wind failed - and able to navigate shoal waters due to its shallow draft, the xebec was the perfect ship for a pirate. It could catch most merchant vessels, and run away from warships that could reduce its lightly-built hull to splinters with a single broadside.
We found in the French Ministry of Defense archives a highly-detailed plan of the Algerian xebec captured in 1830 and placed in service by the French Navy as Le Boberach. She was used mainly as a dispatch ship, where she had a well-documented, albeit fairly uneventful career.

Algerian xebec Le Boberach, captured by the French in 1830

Lack of exciting engagements aside, she still has the exotic lines that would make an eye-catching model for the enterprising modelshipwright looking for something beyond the typical bathtub-hulled square rigger. Thanks to the French proclivity for record keeping, we also have a great deal of information about her service, too.
As an extra treat, we threw in the plans of an 18th Century Algerian xebec documented in Fredrik Henrik af Chapman’s Architectura Navalis Mercatoria.

Plans for a U.S. Coast Guard Cutter

By request, here are free ship plans for a World War II era ex-Navy 133-foot United States Coast Guard Cutter.

Coast Guard Cutter White Sumac

 In addition to the plans presented here, we also have a number of detail plans, including one showing the difference between when the vessel was commissioned in the U.S. Navy and its service as a Coast Guard Cutter.

The U.S. Coast Guard cutter White Sumac was originally constructed as a yard lighter (YF416) for the United States Navy in 1943. This class of vessel provided logistical support to naval operations during World War II. Following the War, the Coast Guard acquired eight of these vessels to use as buoy tenders. The vessel was documented as part of a National Park Service program that documents historically significant engineering, industrial, and maritime sites in the U.S. These plans are maintained by the Library of Congress.

The Model Shipwright offers these ship plans to members FREE as high-resoultion TIFF files, or, we can send you prints of the plans for $10 per 24" x 36" sheet, plus postage. For more information, use our Contact Page to let us know of your interest.
