Is there any easy way of converting Loran coodinates to GPS coordinates ???? Thanks

Blue,
The good news is that there are several software programs that will do it. The bad news is that the results won't be very accurate.

Loran / GPS

It's a shame there isn't a good source to reference Wreck or structure coordinates (loran or gps) on this site. The wreck info for the Sound is terrible and not informative at all.

Do it the "hard" way and enhance your navigation skills. LORAN interpolators are available at boating stores and are cheap. Once you find your spot on a chart with the interpolator, it is a snap to determine Lat/Lon

HERE IS THE FREE SOFTWARE

Here is the link to the free software. I have to warn you that MakoMike is correct. Part of the reason for the conversion not working correctly is that Loran signals have a margin of error of +/- 1/4 mile. That is the main reason why in five or six years the Loran system will be shutoff.

The second reason is that Loran signals work on radio waves that only travel in a straight line and do not take into consideration the curve of the earth. Lat/long coordinates do. The two simply do not convert well on paper or computer.

Here is the link to the free program. It is a DOS program but it runs very well;
