Mariner

What is flat, not a battery, sits in a corner or under a pillow to sleep on a bunk bed most of the time, and often tried to deny as the black sheep of the family?

Master Mariner Sid Stapleton, said: "... important and valuable tools that we have on board our ships." Sailing guru Nigel Calder calls ".... The starting point and purpose of navigation" and the captain of the cruise ship Caribbean Marine Donald Street, said: "It 's rare, as much as possiblemany ... "

Now you can with some of these captains did not agree on priorities, but in my head, the card is there with the boat anchor and sail as the most important instruments on board.

A spark that can make navigation black box, which is enough to lose the mail. So take a minute to get back to basics that must be dead simple to use at any time along the coast or navigation at sea

This is not the manualVersion, but the realistic version of the dead candle easy navigation. That is, no table, spraying the front heel and I feel a bit 'green, all at the same time. It all starts well before you pull the first anchor line.

These seven simple steps and a boat of any size anywhere in the world. So 90% of your letter of safe navigation at sea, where you can choose your own to complete the sail:

1. Plan your route navigation

Use the chart on a larger scale for the area of ​​maritime navigation. shows a larger scale near the ports of entry, anchorages, hazards and past aid to navigation. Take a look behind the title of the letter of the report. The higher the number of seconds, the largest scale.

For example, in U.S. waters, the best maps for coastal shipping in 1:80,000 scale. This means that one centimeter on the map 80 000 cm above the surface. Oncethe coast and enter the ports you want an even larger scale that much better 1:40.000 for details.

Use the "what if" factor in choosing the right scale for the use of cards. What happens if the weather turns bad, or has a wound on board and a port must enter at night, or if you need to find a place for the night. Your navigation map that offers the best features of the day and night navigation safety, marine environment.

2. Draw the line of command(TR)

Does your site sailing school - known as "track lines" - in the letter with a pencil. Use the outer ring of the compass in the direction of real estate. Many people like the magnetic field (second level) with the compass, but not all cards have a magnetic ring. The only real point as used in sea Convert the true meaning of a variation of the magnetic field at the center of the compass.

Add the change to the west, and subtract this variation. For example, ifWe applied a true course of 038 true, and the center of the compass showed a variation of the 3E, subtract the change in the effective magnetic path (035M) to find.

Some cards require wind roses in general. Instead, see magenta (red), oblique lines, ever so often about the properties of the table. These lines are called to comply. Look along the line to find the change. Use the same rules for the conversion, of course, applies to a magnetic fieldCourse.

3. Magnetic label management courses

Write to the magnetic heading at the top of every trace of their lines. Label three digits and a capital M (for magnetic). For example, a magnetic heading of 35 degrees magnetic 035M write at the beginning of the line. For more than 8 degrees magnetic 008M magnetic write on the top line of the runway.

To delete the label, draw a small arrow that breaks between the magnetic labelsthe arrow indicates the direction of travel. For example,-035M-> o-008M->

4. Scan for hazards and Comments

Take the time to fully explore the right, the left line of the runway and in front of her. If you want to take chances with dangerous debris and shallow annotations (flat), rip current areas or others that may ship in distress.

Mark with colored pencils, so they are day and night in all weather conditions. Do not use redFor comments, because it will be invisible if it remains in the red light used for night vision. Instead, with blue, green, magenta (purple sea) or black.

5. the lines of tape on the track

Order of removable tape or a similar mark that can be removed in writing. Stick pen the title and add a strip at the top and bottom (for the marking and tracing of messages). This makes it possible to deliver the letter again and again and again to use the tape, a protective barrierendure a pencil, eraser, and the needle of the partition of the navigation system.

6. Make It Bold and Black

It 'used to draw a fine tip black marker tracks veil on top of the band. Write to the price tag on top of each line of the track with a marker.

7. Lash to a table

Make your table ready in the cockpit. Bend the navigation map. Lash to a size clipboard, legal or use aCartoonist Council with rubber bands. In case of rain, sliding the unit in a plastic zipper-type super-size.

Use these seven tips for super easy to navigate your board the pleasure of the cabin, safer and easier than ever. You'll receive a candle secure browser, always ready, the boat safe!

In ancient times, self-respect sailor who did not go home without a large number of letters in his arm clip and a magnetic compass in your pocket. Today, most of the charts in electronic form and more than likely appear in marine GPS, plotter, or a Combo Drive Marine Electronics.

What is the graphics and how to use it?
In short, the graphics are topographic maps of the region by sea or inland. There are actually two formats, the frameand the carrier. A raster chart is composed of digital images showing the geo-referenced. So you can enter your boat to see the cards in terms of other functions to find, for example, to what extent is the mainland. It can be updated periodically by the NOAA raster maps. Uniform Display bitmap Raster Graphics Systems (DCR) is called, which is the format used NOAA. So if you want to update the matrix board NOAA, you need a plotter orTable on screen, the RCDS is compatible. (NOAA is the National Oceanic and Atmospheric Administration. This is a government agency responsible for oceans and atmosphere).

The second type of graphs, vector diagrams. Vector graphics is a set of paper maps can be overlaid with digital objects and the information collected in a database. NOAA has years of vector used to construct the maps, but they are becoming amore plotters decide to use. The uniform format for vector graphics called NOAA ENC and ENC. NOAA ENC, free upgrades and free. To take advantage of the tracer must be able ECDIS ENC (Electronic Chart Display stands for Edicso and Information) will be.

ENC are real-time information such as tidal currents, gives the coordinates of the limits of the channel, and other geographic information to facilitateNavigation and collision avoidance to be easy. NOAA has completed the image vector information for all major U.S. ports and continue to refine the information on the smaller ports. As with the letters for the points, you can update from NOAA, and add data.

With vector graphics and raster
To use the raster and vector graphics from a third-party commercial software they need, how to process and display the letters known. Most of the plotters and GPS-plotterUse one or both types of graphs. What is the best, raster or vector? It depends on you, the network contains less information, but so far is a complete set of cards. Vector graphics, while still under construction, have made great progress in recent years and is updated each week, while the database is to continue to grow steadily. It will be the most likely option, updates are available directly from the manufacturer of the tracer, but it depends on whether the option to downloaddirectly from NOAA, leads to the smallest details as they become available.
