This video discusses density/relative density, volume, and mass in relation to ship stability and calculates problems relating to these terms.

Density is the mass per unit volume of any given substance.

Relative Density (RD) of a substance is a ratio of the density of the substance in question to that of fresh water.

Mass is a measure of the amount of matter in an object.

Volume is the quantity of three-dimensional space occupied by solid, liquid, or gas.

This video shows how to determine the weight of ballast water inside the tank using a tank-sounding table. It involves interpolation using a scientific calculator.

This video provides a step-by-step guide for determining the Gyro Error and the deviation by the Sun's amplitude using the formula: Sin Amp = Sin Dec / Cos Lat.
Amplitude refers to the angular distance of a celestial body (such as the Sun or Moon) measured along the horizon—from the East point when the body is rising, or from the West point when it is setting.

Correction for the magnetic variation from the compass rose. The answer is 6.75 deg, E or 6.8 deg.E, not 4.75 deg E.
In this comprehensive tutorial, we're diving into the essential skill of determining magnetic variation using both a compass rose and an Electronic Chart Display and Information System (ECDIS). Understanding magnetic variation is crucial for safe and accurate navigation, whether you're a seasoned mariner, a budding sailor, or a maritime student.

Magnetic variation, also known as magnetic declination or compass variation, is the angle between the true north direction (geographic north) and the magnetic north direction indicated by a compass at a specific location on the Earth's surface.

This video defines the ship's lightweight, deadweight, and displacement. Determine the value of displacement using a hydrostatic table.

Lightweight - is the weight of the ship when completely empty. It is a mass of a ship with all of its structures including all steel, decks, cargo gears, and machinery with boilers topped up to working level.

Deadweight – is a measure of how much mass or weight a ship is carrying or can safely carry. The sum of all the weights of cargo, fuel, lubricating oil, fresh water, water ballast, stores, crew, passengers, and effects. It does not include the weight of the ship.

Displacement – is the weight of the volume of water that a ship displaces or the weight of the water that a ship pushes aside when she is floating.

This video shows how to calculate "Fluid GM" with multiple weight scenarios. It provides valuable insights, and practical knowledge and helps you understand how to calculate Fluid GM effectively. Don't miss out on this essential information for anyone interested in ship stability.

Metacentric height (GM) of a ship is a crucial parameter that determines its stability characteristics, particularly its resistance to rolling motions in response to external forces such as waves, wind, and cargo shifting.

Welcome to our educational video on ship stability. In this tutorial, we explore how to determine the Free Surface Moment and VCG (Vertical Center of Gravity) using a Tank Sounding Table. It involves interpolation using a calculator.

"Free Surface Moment" refers to the effect of liquids moving freely within a partially filled compartment or tank on a ship. When a ship heels or lists, liquids within partially filled compartments or tanks will shift, creating a moment that can affect the vessel's stability.

Vertical center of gravity (VCG) is a critical parameter in ship stability analysis, representing the point within a ship where the vertical forces of gravity can be considered to act.

In this video, it shows how to calculate the Fresh Water Allowance & Dock Water Allowance. It includes how to determine the change in the Ship's drafts due to the changes in water Density. Find the Relative Density and determine the arrival draft from salt water to fresh water & vice versa. Determine the arrival draft from dock water to salt water & vice versa.

Fresh Water Allowance (FWA) is the number of millimeters by which the mean draught changes when a ship passes from salt water to fresh water, or vice-versa when the ship is loaded to the Summer displacement.

This video shows how to determine the Assumed Position and its practical use in Celestial Navigation. It includes a brief discussion on how to use AP to determine LOP by celestial observation.

Assumed Position, AP, is a chosen or hypothetical position used primarily in celestial navigation when calculating a ship’s position based on observations of celestial bodies. It is typically not an actual or fixed location but a theoretical one chosen for ease of computation, often determined using the Marcq Saint-Hilaire method with the help of Sight Reduction Tables, Pub. No. 249.

This video shows how to use a hydrostatic table to determine a ship's displacement. It includes interpolation to determine ship displacement. It also defines lightweight and deadweight.

A ship's hydrostatic table, also known as a hydrostatic data table or hydrostatic curves, is a tabulated set of data that provides information about the buoyancy characteristics of a ship at various drafts or immersion levels. It is an essential document used in naval architecture and ship design to analyze a vessel's stability, buoyancy, and trim.

For those onboard using software such as loadicator and other software for cargo distribution, you can use this video as your reference.

Load Lines are markings found on the hull of a ship indicating the maximum depth to which the vessel may be safely immersed when loaded with cargo.

Whether you're a maritime enthusiast, a ship's officer, or a student looking to expand your knowledge, this video is packed with valuable information and practical insights.

Mass is commonly defined as the measure of the amount of matter in an object. It is typically measured in units such as kilograms (kg) in the International System of Units (SI) or grams (g) in the metric system. In some contexts, other units such as pounds (lb) or ounces (oz) may be used.

This video shows you how to determine the Gyro Error by astronomical observation using the celestial body sun. It demonstrates how to use the Nautical Almanac and Norie's Nautical Tables to find the true bearing of the sun.

A ship's gyro error refers to the deviation or discrepancy between the true north direction and the direction indicated by a gyrocompass aboard the ship. Gyrocompasses are used for navigation and provide a stable and reliable reference for determining the ship's heading. However, like any navigational instrument, gyrocompasses are subject to errors, including gyro errors.
