Have you ever wondered why sailors and ship enthusiasts often refer to a ship as “she” or “her” instead of just calling it “it”? 🤔 In this video, we explore the fascinating maritime tradition behind this unique practice. From ancient Latin roots and sailor folklore to the symbolism of protection, grace, and mystery, discover why ships have been lovingly personified as female throughout history. This video will give you a clear and engaging explanation. #MaritimeTradition #WhyShipsAreCalledShe #NauticalHistory #ShipSymbolism #MaritimeEducation #SailorTraditions #NauticalCulture

In this video, we explain the concept of Longitudinal Center of Gravity (LCG) and its importance in ship stability and trim. Learn how LCG shifts when weights are moved, how to read LCG values from a stability booklet, and what positive and negative LCG values mean. The Longitudinal Center of Gravity (LCG) is the longitudinal distance—either forward or aft—from a chosen reference point, typically from midships, or from the aft perpendicular. #navalarchitecture #stability #hydrodynamics #maritime #seafarer #seaman #bsmt #maritimestudents #seamanship #trim #nauticalacademy

Learn what Block Coefficient (CB) means in ship stability and how it directly affects squat when a vessel is underway. We’ll break down the differences between full-form, fine-form, and moderate-form hulls — and explain how squat behavior varies for each type. #navalarchitecture #stability #hydrodynamics #shiphandling #maritime #seafarer #seaman #bsmt #maritimestudents #seamanship #trim #nauticalacademy https://youtu.be/6YmnkoMBfFQ
This video covers the concept of bilging and how a flooded compartment affects a ship’s draft, metacentric height (GM), and righting moment. The calculations are based on the Lost Buoyancy Method, also known as the Constant Displacement Method. A bilged ship is one that has suffered a breach of the hull, typically through grounding, collision, or similar incidents, resulting in water entering the hull. #navalarchitecture #stability #hydrodynamics #maritime #seafarer #seaman #bsmt #maritimestudents #seamanship #trim #nauticalacademy
In this video, we break down the basics of ship stability by explaining key concepts like the law of flotation, displacement, density, and volume.

This video shows a step-by-step guide on how to determine the zone time or local time of sunrise when the given date is NOT in the Middle Day of the daily page of the nautical almanac. It also includes how to convert arc to time or convert longitude into longitude in time (LIT). #celestialnavigation #navigation #maritime #seafarer #seaman #bsmt #interpolation
In this video, it shows how to use Navi-Planner 4000. A basic familiarization & passage planning. Navi-Planner 4000 is an advanced voyage planning and chart management software, originally developed by Transas. It is primarily used for voyage preparation. It enables route planning, chart management and updating (ENC/SENC), voyage optimization, and simulation before the ship proceeds to actual navigation. #ecdis #naviplanner #navisailor #radar #colreg #collisionregulation #navigation #passageplanning #seamanship #maritime #seafarer #seaman #bsmt #maritimestudents
This video shows how to determine the GHA, LHA, SHA, RA, and Meridain Angle ("t") of the celestial bodies through time diagram. Time Diagram is a conceptual tool used to illustrate the relationship between Greenwich Hour Angle (GHA), Local Hour Angle (LHA), and longitude. All of which are angular measurements connected to time and position on Earth. #celestialnavigation #navigation #maritime #seafarer #seaman #bsmt
This video provides a step-by-step guide to determining the Gyro Error and the deviation using the Sun’s amplitude, based on the formula: Sin Amp = Sin Dec / Cos Lat. It demonstrates two methods for finding the deviation when variation is applied to the total error. Additionally, the video corrects an error from Parts 1 and 2 regarding the proper naming of the Sun’s amplitude suffix. 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. #celestialnavigation #navigation #maritime #seafarer #seaman #bsmt
This video explains waht is hogging and sagging. It covers the importance of knowing it and how to determine if the ship is hog or sag through her drafts. Hogging occurs when the ship’s middle portion (amidships) is lifted higher than its bow and stern. This happens when excessive weight is loaded at the fore and aft parts of the ship, causing the amidships section to rise. The uneven cargo distribution, with a large amount of weight concentrated toward the ends, increases buoyancy at amidships, leading to hogging. Sagging is the opposite of hogging, occurs when the ship’s bow and stern rise, while the middle or amidships portion sinks lower. This happens when excessive weight is concentrated in the midsection of the ship, causing it to sink lower. Poor cargo distribution, such as heavy cargo stowed amidships, while the bow and stern remain light, reduces buoyancy at midship, leading to sagging. #stability #hydrodynamics #maritime #seafarer #seaman #bsmt #maritimestudents #seamanship https://youtu.be/C5IC49f0Lwo

This video explains the concept of ship draft, highlighting its critical role in maritime safety and operations. It guides you on how to read draft marks. Ship's draft is the vertical distance between the lowest point of the ship's hull, known as keel, and the waterline. #stability #hydrodynamics #maritime #seafarer #seaman #bsmt #maritimestudents #seamanship #trim
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. #stability #hydrodynamics #maritime #seafarer #seaman #bsmt #maritimestudents #seamanship #trim
