How to navigate a boat

Pilotage involves navigating in restricted waters with the determination of position being relative to geographic and hydrographic features.

Celestial navigation means reducing celestial measurements to lines of position using tables, spherical trigonometry, and almanacs.

Radio navigation uses radio waves to determine position by either radio direction finding systems or hyperbolic systems.

Radar navigation determines the distance from objects whose position is known.

Maritime charts - Road maps of the waterways! Without road signs and landmarks, maritime charts rely on features invisible to the naked eye:

Water depth Location and description of navigational markers Longitude and latitude lines Shapes of land masses

A maritime chart will shows all hazards, landmarks, markers and safe passages. If you're taking a journey out to sea, even if it's short, have a maritime chart to hand, and ensure you are able to use it!

Along the edges of the chart are the latitude and longitude lines - horizontal and vertical. The place where these lines meet offer a coordinate for any point in the world. So, if you know your location coordinate, then you'll never be lost.

Maritime charts are printed in colour to convey important information. For instance, a light blue colour indicates the water is between 1 and 3 fathoms in depth and offers safe passage for most boats.

Did you know? The word navigate comes from the word "Navi", which in Sanskrit means 'boat' and "Gathi" means 'direction'.

Compass - Modern technology may be sophisticated but they are they always reliable? It's always a good idea to have a back up system. The compass is merely a small magnet suspended on a pivot point, but a compass can always be relied upon to get a boat back to land.

Electronic navigation is a luxury for those puttering around lakes, rivers and coastlines but vital for anyone boating away from land. It is to date the easiest and most reliable way of keeping track of ones location.

Dead reckoning - Dead reckoning, or DR, is the process of estimating your present position by projecting course and speed from your past position. It's also used to predict future position by projecting course and speed from a known present position. The DR position is only an approximate indication of your position, and does not allow for leeway, current, helmsman error, compass error, or any other external influences.

Navigation Courses - The Royal Yachting Association (RYA) has offers a two day basic introduction to navigation course. Taught at boating centres across the UK, this course is ideal for those new to boating who want to pick up some essential navigation skills. More experienced navigators can take part in the more advanced RYA skippering courses, including subjects like meteorology, collision avoidance and passage planning.

Other ways to navigate your boat - Pilotage involves navigating in restricted waters with the determination of position being relative to geographic and hydrographic features.

Celestial navigation means reducing celestial measurements to lines of position using tables, spherical trigonometry, and almanacs.

Radio navigation uses radio waves to determine position by either radio direction finding systems or hyperbolic systems.

Radar navigation determines the distance from objects whose position is known.

Electronic Star MD-063 Electronic Compass GPS Navigation $54.9 The Electronic Star MD-063 is a helpful GPS compass designed to be used both home and abroad. The compass combines user-friendly functionality with a three position GPS memory and a distance indicator. These features together with the built-in clock make the GPS compass the perfect companion on your next hike. In addition to its outdoor applications such as storing the location of camp sites or meeting points, the compass is well suited to urban use, such as locating a carpark, your hotel or a great bar in an unfamiliar city. The electronic compass weighs an incredibly light 60g (including batteries) and will barely affect your travelling weight. The device has been designed as a perfect compromise between usability (i.e. readable display and workable controls) and compact size. The compass's highly visible yellow colour prevents it from being lost in grass or on other difficult terrains. Thanks to its very modest power consumption, the GPS compass can be taken on even the longest hikes without any fear of power loss. Please note that GPS reception can be affected in the immediate vicinity of tall buildings or inside buildings.

Inner Navigation $14.99 A FASCINATING INVESTIGATION OF HOW WE NAVIGATE THE PHYSICAL WORLD, INNER NAVIGATION IS A LIVELY, ENGAGING ACCOUNT OF SUBCONSCIOUS MAPMAKING. Why are we so often disoriented when we come up from the subway? Do we really walk in circles when we lose our bearings in the wilderness? How -- and why -- do we get lost at all? In this surprising, stimulating book, Erik Jonsson, a Swedish-born engineer who has spent a lifetime exploring navigation over every terrain, from the crowded cities of Europe to the emptiness of the desert, gives readers extraordinary new insights into the human way-finding system. Written for the nonscientist, Inner Navigation explains the astonishing array of physical and psychological cues the brain uses to situate us in space and build its "cognitive maps" -- the subconscious maps it employs to organize landmarks. Humans, Jonsson explains, also possess an intuitive direction frame -- an internal compass -- that keeps these maps oriented (when it functions properly) and a dead-reckoning system that constantly updates our location on the map as we move through the world. Even the most cynical city-dweller will be amazed to learn how much of this innate sense we use every day as we travel across town or around the world. Both a scientific and a human story, Inner Navigation contains a rich assortment of real-life insights and examples of the navigational challenges we all face, no matter where or how we live. It's a book that is as provocative to ponder as it is delightful to lose yourself in. Don't worry: Erik Jonsson will help you find your bearings.

Avian Navigation $189 How migratory birds can navigate home from their wintering grounds to their breeding sites over hundreds and thousands of kilometres has been an admired mystery over more than a century. Profound advances towards a solution of this problem have been achieved with a model bird, the homing pigeon. This monograph summarizes our current knowledge about pigeon homing, about the birds' application of a sun compass and a magnetic compass, of a visual topographical map within a familiar area and -- most surprisingly -- of an olfactory map using atmospheric chemosignals as indicators of position in distant unfamiliar areas.

Gimballed Collectors Compass $120 Its origin was from ancient China. Considered an instrument of magic by many, it was used primarily for Feng Shui purposes.

Its elegant design features gimbal-rings, which serve to keep the compass bowl horizontal, regardless of how much the vessel is heeling over. Hand-tooled in admiralty brass.

Wilderness Navigation Handbook $9.99 Designed for both land and water use, this comprehensive guide helps unlock the complexity of map and chart reading as it relates to navigation. Beginning with detailed technical descriptions of the tools of navigation—a compass, an altimeter, a GPS system, and a sextant—this handbook shows how to use these tools either individually or in combination with each other to navigate any area. Factors that cause tools and techniques to fail are discussed, such as why an altimeter often shows the wrong elevation, a GPS position is sometimes off track, and the sun often points in an unexpected direction. Twenty-one real-life scenarios provide practical wisdom for even the most intrepid navigator. Specific information on using the moon for directions and the stars for position, measuring boiling water temperature for elevation, map projections, map datums, great circle routes, and the UTM/UPS grid system is included.
