LORAN Still Worth The Trouble?

The corrections typically apply only to a limited area since they are the result of charting error, not GPS lat/lon error. In my experience it is all too easy to forget that you have applied an offset ... I did this quite a bit the first time I visited Nova Scotia. At that time the GPS system did not exist for recreational yachts. Earlier, also pre-GPS, I had used this method in Bermuda and, later, the Bahama Islands. As you note the range for these corrections is quite limited, but it was essentially "the only game in town" if one wanted to have some sort of electronic piloting information available. However according to several "experts" (including ALL the available cruising guides and several correspondents who have make passages to the area), the south and southwest shore of Newfoundland is covered by charts that do not match up to GPS data. I am referring to the latest CHS paper charts and the latest NDI electronic charts, all corrected to the latest updates available. So it seems that using the old LORAN offset trick would at the very least provide useful additional piloting information. That's the idea I'm toying with. -- Good luck and good sailing. s/v Kerry Deare of Barnegat http://home.comcast.net/~kerrydeare |
