    ATTENTION ALL GPS USERS

    DAYLIGHT SAVINGS TIME BEGINS SUNDAY, APRIL 2, 2006 AT 2:00 A.M. ~

    ~ This Saturday night reset your clocks forward one hour. ~ ~ ~

    ~ ~ ~ ~ ~ Spring Ahead / Fall Back ~ ~ ~ ~ ~

    Remember also to re-configure your GPS unit to Easternl DAYLIGHT SAVINGS Time.

    U.S. EASTERN Daylight Savings Time is MINUS FOUR HOURS (– 04 hrs.) from Universal Time Coordinated (UTC).

    By resetting your GPS unit, it will properly display the correct time of the day, and will accurately estimate the proper “time of arrival” (ETA), etc., figures.

    A comment titled: Raritan Wreck in response to a report titled: Horshoe and Raritan

    ~ Captain Paul's response to: ~ Scott ~

    I am not really sure that this is the Horseshoe you are speaking about, but…

    I have found several features that resemble a horseshoe, but one is very prominently displayed as a shoal 15 to 17 feet deep in surrounding water that is 24 to 28 feet deep. It is located about 3.25 Nm from the Frying Pan Shoals Slue Aid to Navigation (ATON) Green Can # 1, on a bearing of 131º magnetic. The horseshoe shaped shoal is at or about 33º 37.947’ N. lat.~ 77º 49.318’W. long. The open end of this formation faces southeast.

    Raritan – Was a 251 ft. freighter. It sank in 1942 in about 80 ft. of water. She is in two sections, with the bow being separated from the rest of the wreck. The bow and stern sections were reported as being still intact.
    It can be found on NOAA chart 11536. It is shown in a water depth of 50 feet.
    NOAA AWOIS database indicated that the wreck is between
    LAT 33° 32’ 29.5” N ~ LONG 77° 56’ 50.4” W and 33° 32’ 30.18” N ~ 77° 56’ 53.83” W longitude

    Unless otherwise specified, all positions are stated as H,DDD,MM.mmm and were determined using WGS 84 DATUM. All Headings/bearings/courses are stated in Magnetic Degrees.

    A comment titled: Different Position Formats in response to a report titled: GPS Formats ?

    ~ Captain Paul’s Response to Bill Acree ~
    The Garmin position format is configured to read degrees, minutes and thousandths of minutes. (DDD,MM.mmm) Using this format is generally the most accurate way to represent a position using a consumer type GPS receiver.

    a change in the last position after the decimal point of one integer (.001 to .002) amounts to a position change of 6.076 feet.

    At this latitude, one minute of a degree of llatitude equals one nautical mile or 6076.115 feet. Therefore, one tenth of a nautical mile (.m) equals 607.612 feet, one hundredth of a nautical mile (.mm) equals 60.7612 feet and one thousandth of a nautical mile (.mmm) equals 6.076 feet.

    In the DD,MM,SS.S format, one digit difference in the place after the decimal (00.1”) equals about 10.1 feet of latitude. The DD,MM.MMM is a more precise way to state a position than DD,MM,SS.S.

    The position you describe as showing in your PDA loaded with Maptech mapping software, appears to be shown in degrees, minutes, seconds and hundredths of seconds (DDD,MM,SS.ss)
    The position should actually shown as N 35* 26’ 48.26”, etc.

    There are three ways to have both units “speaking” in the position format language. Either change the Position Format setting in the Garmin or preferably change the Maptech software to display the positions in the same format as the Garmin unit.

    For Maptech Offshore Navigator including Digital Chartkit,
    Click on “View” in the top tool bar, then click on “Options.”
    Once the window appears, find the LAT/Long format box and select the DDD,MM.mmm format from the drop down box that will appear when you click on the arrow.

    If you are operating the Maptech TERRAIN Navigator software, click on “File,” then “Preferences,” then “General.” When the drop down General window appears, select the “Coordinates arrow and change the format to D,M.M. This setting will display the PDA positions in the same format as the Garmin.

    Now that we discussed two ways, you can use the third, although it will require a little math on your part. The third way is to manually convert either position to the other.

    To convert seconds and tenths of seconds (SS.S”) to thousandths of a minute, divide by 60. (30 seconds divided by 60 = .500 minutes)

    To convert thousandths of a minute (.MMM’) to seconds SS.S”), multiply the thousandths of minutes by 60. (.210’{minutes} x 60 = 12 .6” {seconds}).

    ~ Remember that almost as important as the position format, is the DATUM that was used to obtain the position. The difference between NAD 27 and WGS 84 could result in a shift in the physical position as much as 400 feet

    When obtaining and entering a position that you may want locate, plot to or from a map, you should determine what DATUM was used to obtain the position and convert it to the datum used by the map. The coordinates (waypoints) should be entered using that DATUM.~ Entering a position that was obtained using one datum as a position in another datum can cause another error in position. I have seen a position error of over 1200 feet caused by using the wrong datum.

    So, be sure that the DATUM in both units are in the same format.

    A comment titled: AWOIS is the #1 Source in response to a report titled: Where is the best place to locate wreck coordinates?

    <font color=’blue’><b> ~ Captain Paul’s Response ~ </font color>

    I don’t know of any ONE publication that shows all that you asked for as a single item, but there are several sources that can provide you with the needed information.

    Using a NOAA marine chart for the area you are interested, access the <i>NOAA Office of Coast Survey's Automated Wreck and Obstruction Information System (AWOIS). </i> You can reach the site at <font color=’blue’> http://chartmaker.ncd.noaa.gov/hsd/hsd-3.html </font color>

    The free AWOIS data bank contains information on approximately 10,000 submerged wrecks and obstructions in the coastal waters of the United States. Information includes latitude and longitude of each feature along with brief historic and descriptive details.

    If you have a general idea of the Latitude and Longitude, you can search for and find all wrecks and obstructions within your described search area. Or you can search those sites located within a designated chart. It as then easy to then copy the positions of the described sites and then enter them into your GPS unit.

    A comment titled: SAME OLE HOLE in response to a report titled: Posted by Jack Stanford


    <font color=’blue’><b> ~ Captain Paul’s Response to ~ JACK STANFORD ~ </font color>

    Get a current issue of NOAA chart 11520- Cape Hatteras to Charleston. It will assist you planning your trip and let you visualize the position of the Same Ole area. The area is normally considered to be at or about 33° 23.500’ N. Latitude ~ 77° 05.000’ W. Longitude.

    The area to the North and North west of this area has a bottom depth between 26 to 32 fathoms.

    At about this location and continuing to the north east to about 33° 25.122’ N. Latitude ~ 77° 04.650’ W. Longitude ( and further) the ledge drops to a depth of 60 to 80 fathoms and within three miles to the South west is about 150 fathoms.

    The area is about 31 miles from the southeastern most Frying Pan Shoals light at a heading of 110° magnetic.

    <i>Unless otherwise specified, all positions are stated as H,DDD,MM.mmm and were determined using WGS 84 DATUM. All Headings/bearings/courses are stated in Magnetic Degrees.</i>
