SEAM 1 Flashcards
Study
It’s the watertight body of a ship, boat, submarine, or flying boat. It’s essentially the main structure of the vessel, providing buoyancy, stability, and protection for the cargo, machinery, and crew.
Hull
These hull rely primarily on buoyancy to support the vessel. They are common in larger ships and are characterized by their rounded bottom.
Displacement Hull
These hull combine elements of displacement and planning hulls, offering a balance of stability and speed.
Semi-Displacement Hull
These hulls are designed to lift out of the water at high speeds, reducing drag. They are often used in smaller, high-speed vessels.
Planing Hull
It’s the front or forward part of a ship. It’s the section that first encounters waves and obstacles in the water.
Bow
A sharp, pointed bow designed for ramming other vessels, often used in military applications.
Ram Bow
A bow with a wide, flared shape that helps to deflect waves and improve stability.
Flare bow
A large, bulb-shaped structure attached to the bottom of the bow that reduces drag and improves fuel efficiency.
Bulbous Bow
It’s the rear or aft part of a ship. It’s the section that trails behind the vessel as it moves through the water.
Stern
is a stern shape characterized by a generally flat shape extending to the waterline.
Transom Stern
It’s a stern with a counter or overhang that improves stability and reduces drag.
Counter Stern
It’s the backbone of a ship, running lengthwise along its bottom. It provides structural support, stability, and a reference point for measuring the vessel’s draft (the depth to which it sinks in the water).
Keel
It’s the horizontal surface or platform on a ship, boat, or other vessel. It provides a space for crew members to work, passengers to move around, and cargo to be stored.
Deck
Three materials for Deck
Wood, Steel, and Composite Materials
The primary deck of a ship, usually located near the waterline. It often houses the ship’s machinery and crew quarters.
Main Deck
A deck located above the main deck, providing additional space for passengers, crew, or cargo.
Upper Deck
A deck designed for walking or strolling, often located near the top of the ship.
Promenade Deck
A deck specifically designed for carrying cargo, often located below the passenger decks.
Cargo Deck
the upper deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors’ living quarters.
Forecastle Deck
It’sthe main security check point aboard a vessel when it is in port or anchored. This is the area of the ship where the gangway is rigged and the watch is posted.
Quarter-Deck
These areinner walls within the hull of a ship, used to separate it into smallercompartments.
Bulkheads
Types of Bulkheads
These are designed to prevent the passage of water, even under pressure. They are typically used in areas where flooding could pose a serious risk, such as engine rooms or cargo holds.
Watertight bulkheads
Types of Bulkheads
These are designed to resist the spread of fire for a specified period of time.
Fire-resistant bulkheads
It’s the lowest part of a ship’s hull where water and other liquids accumulate. It’s essential for collecting and removing these substances to prevent them from compromising the ship’s stability and causing damage.
