Glossary of Shipbuilding Terms Explains the Arcane

Whether you are just starting in the hobby of model shipbuilding or are an old pro, there are times when you will find mysteriously arcane terminology that traditional dictionaries don't define.
Our Glossary of Shipbuilding Terms comes from Charles G. Davis's The Building of a Wooden Ship (1917) which was written to familiarize carpenters and cabinetmakers with the art of shipbuilding.

We've added illustrations from a number of period sources and comments to help with comprehension of these terms, many of which have few, if any, modern equivalents.

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.

Italian Brigantine Schooner Gigino

Demonstrates Pinnacle of Sailing Ship Design

What Chapelle would term "Hermaphrodite Brig"

20th Century Italian Brigantine Schooner Gigino

As steam powered ships threatened to finally replace sail for ocean-going cargo vessels, this pressure led naval architects to the pinnacle of their design skills. The final sailing ships balanced capacity with fine lines that allowed greater speed while carrying the maximum amount of cargo.

Another major design change was the change from square sail rigs to fore-and-aft sails. These schooner rigs required fewer sailors to handle the ropes, allowing sailing ships to remain financially competitive with the smaller crews of steam ships. The "brigantine schooner" - or "hermaphrodite brig," as American historian Howard I. Chapelle would name it - combined the two sail rigs with square sails on the forward mast and fore-and-aft sails on the main mast, giving it positive benefits of both sail types. These sailing ships remained competitive with steamships well into the 20th Century.

Our free ship plans of Italian brigantine Gigino offer a large body plan with ships' curves, as well as a detailed framing plan, section plan, keel and deadwood plan, and sail and rigging plan.

Adding Chine Strips to the Chesapeake Bay Flattie

Next up in our construction of the Midwest Products Chesapeake Bay Flattie ship model kit is to create a supporting surface for the bottom and side planks by adding keel and chine strips.

The keel strips lie along the keel to keep the bottom planking from sagging between the bulkheads.

The chine strips run along the edge where the bottom and sides of the boat meet. The Chesapeake Bay Flattie is considered a "hard chine" boat due to the acute angle at which the side and bottom planking meets. The chine "logs" on a boat like this provide strength to the hull as well.

Fletcher-class Destroyer U.S.S. Capps

Saw World War II Service in Atlantic and Pacific Theaters

Then Went on to Long Career in Spanish Navy as Lepanto

Fletcher-class destroyer USS Caps during service for Spain as Lepanto

U.S. Navy Fletcher-class destroyer U.S.S. Capps (DD-550), built by Gulf Shipbuilding Corp. in Chickasaw, Alabama, was launched in May 1942 and commissioned in June 1943.
A member of the Fletcher class, the largest class of destroyers built during World War II, she served in a number of operations in both the Atlantic and Pacific theaters of operation during World War II including raids on German ports, escort duty, and the battles of Iwo Jima and Okinawa.
After being decommissioned by the U.S. Navy, she was transferred to the Spanish Navy, where she served until 1985 as Lepanto.
Our USS Capps Plans Page features plans of each of her decks, inboard and outboard profiles, sections, and body plans perfect for model ship construction.

U.S. Coast Guard Cutter Acushnet serves 67 year career

That began as U.S. Navy salvage vessel USS Shackle

Decommissioned in 2011, she was the only World War II vintage vessel still in Coast Guard service

USCG Cutter Acushnet/USS Shackle

U.S. Coast Guard cutter Acushnet's long career began during World War II as U.S. Navy salvage ship USS Shackle (ARS-9). After joining the Coast Guard, she served as a tug, oceanographic research vessel, and medium-endurance cutter. 

With the attack on Pearl Harbor, navy shipyards were suddenly hard-pressed to build all the new vessels that would be required for the war effort. The U.S. Navy turned to the U.S. Maritime Commission to contract many of the attack transports, oilers, and other auxiliary ships it needed, such as salvage ships.

Outboard profile USCG Cutter Acushnet

While the first task of salvage ships was to clear the damaged ships in Pearl Harbor, duties went beyond dealing with destroyed or sunken ships to any repair tasks beyond the scope of a ship's crew, such as fire-fighting or towing disabled craft. The Navy used every resource possible – both military and commercial salvage company - in the design of what would be named the Diver class salvage vessel to which Shackle/Acushnet belongs. Her keel was laid in October 1942 at the Basalt Rock Company shipyard located on the Napa River, and she was launched February 1944. This shipyard constructed all 16 Diver class salvage ships.

 U.S.C.G. cutter Acushnet/U.S.S. Shackle has great lines and would make for a great ship model, built from the free ship plans available at TheModelShipwright.com

The Only Remaining Steam Tug on the West Coast

A great subject for a historic ship model

Steam Tug Hercules

In 1907 the San Francisco firm The Shipowners and Merchants Towboat Company ordered two ocean-going tugboats from John Dialogue and Son of Camden, New Jersey, builders of tugs, pilot boats, and small steamers. At the turn of the century many harbor tugs were built with wooden hulls and powered by a compound two-cylinder steam engine of about 500 horsepower. Hercules and her sister Goliath instead were built with 150 foot riveted steel hulls and triple expansion three-cylinder 1000 horsepower steam engines.

The only remaining ocean-going steam tug on the West Coast, Hercules was designated a National Historic Landmark in 1986. She was was documented as part of the Historic American Engineering Record, a program of the National Park Service. 

Our photo gallery of steam tug Hercules features high-resolution photographs from that survey that are kept by the Library of Congress.

Building Midwest Products' Chesapeake Bay Flattie Model Ship Kit

Midwest Products' Chesapeake Bay Flattie

Plank-on-Bulkhead Model Ship Kit

Promises Ease of Construction

Midwest Products Chesapeake Bay Flattie kit.

While solid-hull ship models are generally considered the easiest to construct, Midwest Products has created a "Success Series" of ship model kits that offer plank-on-bulkhead models that promise to make model shipbuilding easy for the complete novice.

We decided to test this theory by making Midwest's Chesapeake Bay Flattie ship model kit our first on-line kit build. The simple lines of these boats that made them ideal for locals to build from locally-available lumber should also make this an ideal ship model kit or a person with no prior wood ship model building experience.

The biggest challenge of plank-on-bulkhead ship models is planking the hull, and because of the simple shape of these boats, this task is accomplished in this kit with a single plank on each of the sides, and two planks on the bottom.

The kit comes with well-executed die-cut and pre-cut parts, as well as fittings, rigging line, sail material, and a well-done set of instructions and building plans.
