Types of Sailings Used in Navigation

Navigating the sea is a complex process that requires an understanding of the various techniques used to sail across the open waters, and it is essential to have knowledge of the seven types of sailings we use in navigation: rhumb line sailing, traverse sailing, parallel sailing, mid-latitude sailing, mercator sailing, and great-circle navigation. In this article, we will explore each type of sailing and their uses in navigation so that you can understand how to best use them for your own journey at sea!

Rhumb Line Sailing

Rhumb line sailing is one of the oldest forms of navigation used at sea and is still used today by sailors. It involves following a line on a compass or chart that has an equal bearing to all points on it; this is also known as a loxodrome or rhumb line. This type of sailing allows for efficient travel between two points, regardless of where they are located on the globe – making it a popular choice for many sailors!

Traverse Sailing

Traverse sailing is a form of navigation which uses bearings taken from landmarks on land or fixed points on a chart to determine the course and speed in order to reach a destination point. This form of sailings requires precise calculations as it involves plotting out bearings from observed landmarks or fixed points on a chart before setting off – this ensures that you are heading in the correct direction to reach your desired destination! The accuracy of traverse sailings can be improved by using multiple bearings from different landmarks or points on the chart as well as double-checking calculations before setting off on your journey at sea!

Parallel Sailing

Parallel sailing involves following two parallel lines on a chart with an equal distance between them; this technique is especially useful when navigating close to land or other obstacles such as reefs where exact courses must be followed in order to avoid them safely! The distance between these two lines changes depending upon what type of voyage you are undertaking – shorter distances are used for shorter voyages while longer ones are used for longer voyages! By following these two lines closely and adjusting your course accordingly, you can ensure that you stay within safe limits while navigating close to land or other obstacles at sea!

## Mid-Latitude Sailing

Mid-latitude sailings is one type of navigation which requires more complex calculations and more precise measurements than other types; it involves plotting out specific courses based on certain angles taken from various points along the way in order to reach your destination safely! This type of sailings takes into consideration both magnetic variation (the difference between true north and magnetic north) as well as compass variation (the difference between true north and compass north). By taking all these factors into account when plotting out courses, you can ensure that you are heading in the correct direction and reaching your destination safely!

## Mercator Sailing

Mercator sailings is another type of navigation which requires precise calculations but has been made much easier due to advances in technology; it involves plotting out courses based off a Mercator projection map which shows true directions relative to each other – this makes it much easier for sailors to accurately plot out their course without having to take into account variations caused by magnetic or compass deviation! This type of sailings can be especially helpful when navigating long distances without having access to accurate charts or landmarks on land – making it ideal for ocean voyages!

## Great-Circle Navigation

Great-circle navigation is an advanced form of navigation which uses mathematical calculations based off spherical trigonometry in order to plot out courses – this method takes into account both longitude and latitude when calculating distances and angles between two points on a map! This form of navigations allows sailors to calculate their exact position relative to any given point along their journey – making it ideal for long voyages across open waters where accurate readings must be taken in order determine one’s exact location at all times!

## Conclusion

Navigating the seas requires an understanding of various techniques and tools used by sailors in order to get from point A to point B safely; by having knowledge about each type of sailing we use in navigation (rhumb line sailing, traverse sailing, parallel sailing, mid-latitude sailing, mercator sailing, great-circle navigation) you can be sure that you will have all the information needed for successful voyage at sea! From plotting out courses with precision accuracy using traverse sailings near land or reefs, knowing how best use rhumb lines when travelling long distances across open waters – being able to understand each type’s strengths and weaknesses will help ensure safe travels no matter what conditions may arise along your journey at sea!
