Navigation has been a crucial skill for sailors throughout history. Before the advent of modern technology, sailors relied on various techniques to navigate the vast oceans and reach their destinations safely. One such technique, known as dead reckoning, played a vital role in maritime navigation. This article explores the concept of dead reckoning, its principles,…
For centuries, sailors have relied on the magnetic compass as a primary navigation tool at sea. However, magnetic compasses are subject to errors caused by various factors. One such error is deviation, which refers to the discrepancy between the magnetic compass reading and the true magnetic direction. This article explores the concept of sailing deviation,…
Navigating at sea requires mariners to factor in various elements, including wind, current, and vessel-specific characteristics. When sailing, the concept of Estimating Position (EP) with leeway becomes crucial in accurately determining a vessel’s position. This article explores the concept of EP with leeway, its significance in sailing navigation, and the methods used to account for…
Meteorology, the study of the Earth’s atmosphere and weather patterns, plays a crucial role in maritime navigation. Understanding meteorology enables sailors to anticipate and navigate through changing weather conditions, ensuring the safety and efficiency of their voyages. This article provides an overview of meteorology, its key concepts, and its significance in marine navigation. The Basics…
Handling a yacht under power is an important skill for sailors, as it allows for maneuvering in and out of marinas, docking, and navigating in confined spaces. While sailing is often associated with wind power, understanding how to handle a yacht under power is equally crucial for a well-rounded sailing experience. This educational article explores…
