Boat Navigation at Sea.
A beginner's guide.

Navigation at sea, what you should know about tides, GPS, charts, coastal and celestial navigation and passage planning.

The skill of Boat Navigation is as much an art and a craft, as it is a science.

There are few more exhilarating experiences than that of arriving at a new destination at the end of a passage at sea.

The cry of "Land Ho" is still a glorious whoop, even today when modern electronic navigation aids remove most of the uncertainty from determining your position.

However, it is the very accuracy of positioning and its ease of use that tends to encourage too much reliance on it alone.

is an aid to navigation and safety afloat which, like the echo sounder it would be foolish for the modern boater to ignore.

But it is important that it should be regarded as an aid, and used in consort with more traditional methods as well as an understanding of the watery environment.

As well as the safety aspect of understanding how , and such like will affect your boats progress.Learn NavigationBoat Books on-line

The more you know, the greater will be the enjoyment and satisfaction you will gain from being afloat.

The more you learn about the rare art of finding your way at sea the more skillful you will become and the more enjoyable and enriching will be your voyaging.

And any voyage will be more enjoyable if it has been planned in advance and the planning process itself should be fun.

, apart from being a requirement under the COLREGS, will allow you to collate and assess the all aspects of the trip.

So, before you set off;

"There is nothing so distressing as running ashore.

Unless there is also doubt as to which continent the shore belongs."

  • Enter and check all your waypoints.
  • Evaluate how the and currents will affect all stages of the journey.

  • Make sure you have all relevant paper and harbour plans including any ports which might have to be used in an emergency.

  • Check your and make note of the relevant variations and deviations.

  • Make a list of all geographic and hydrographical features, lighthouses

  • Check the and plan accordingly.

When you do leave port, keep a written record of all stages of the trip in your boat navigation log book, this is also a requirement under the COLREGS.

It is also a very prudent back up to mark your progress on that paper chart.

I know that it is rare for the latest marine units to go wrong and they are now so cheap that many folk, like me have a spare hand-held tucked away, with spare batteries, in a waterproof container.

However, why take the risk of relying solely on electronics.

Pleasure boating like any pursuit becomes more pleasurable as your knowledge increases.

With boating this means not only understanding the environment but having a respect for it, in all its moods.

With boat navigation the more you know the safer you will feel and more your pleasure will be enhanced.

"Setting the course, keeping the dead reckoning up to date, and fixing the position by observations of the celestial bodies, call for nothing more than simple arithmetic, a little geometry, and some dexterity in handling a sextant."
