This video shows how to create parallel index lines and set it to radar. It shows how to determine the PI lines including the Not More Than (NLT) and Not Less Than (NMT) PI lines when making a passage plan.

Parallel indexing is a navigation technique used by mariners to maintain a safe distance from a navigational hazard or to ensure that the vessel stays on a desired track. This method involves using radar and electronic navigational charts, or paper charts to create reference lines, known as index lines," parallel to the ship's course, to continuously monitor a vessel’s track, to a pre-determined passage plan.

This video shows how to calculate the number of shackles to be dropped when dropping a ship's anchor. It includes determining the number of shackles that have been dropped by reading the markings on the anchor chain. The calculations are just a reference. There are other methods of calculations and you can use the method you are familiar with.

A ship's anchor is a heavy device typically made of metal that is used to secure a vessel in place by gripping the seabed. Anchors are crucial maritime equipment for ships of all sizes, ranging from small boats to large ocean-going vessels. They are essential for various maritime operations, including anchoring in ports, harbors, and offshore locations, as well as during emergency situations or when conducting maintenance activities.

This video shows how to calculate a ship's Trim, Change of Trim (COT), and Moment to Change Trim by 1cm (MCTC). It also shows how to determine MCTC using a hydrostatic table.

Trim is the difference between the vessel's forward and aft drafts, measured at the respective perpendiculars.

Change of Trim (COT) refers to the variation in a vessel's longitudinal inclination due to a change in weight distribution.

Moment to Change Trim by One Centimeter (MCTC) is the trimming moment required to change the ship’s trim by one centimeter.

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.

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.

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 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.
