Company History
Carl Andren, the creator of this program, is a member of the Institute of Navigation, the International Loran Association, and the Institute of Electrical and Electronic Engineers. He holds 26 patents in electronics including some on the technology known as WiFi.
The program has been re-branded several times to follow the progression of technology. It started out as The Loran Program when Loran was the only means of electronic navigation. When GPS came along and began to make inroads, the name was changed to The Loran/GPS Program. Later that was shortened to LoranGPS. Now that GPS is the only thing used by fishermen, the Loran-centric name was changed to SeaMarks (think wet landmarks).

Fixed a bug in the Furuno TZD export that made it export only one point. Bug introduced 4/24/20,
5/13/19 Big change! We switched to a virtualized mode for the program. This involves combining all functions, resources, and libraries into one executable (boxed app) that does not have to be "Installed". Thus, the program can run on a removable disk (flash drive) as well as the usual location on the hard drive. As for the hard drive, we supply a simple 'installer' that creates a place (folder) for the program on the hard drive, copies the program there, and creates shortcuts. While the experienced customer could do this, many of our customers are not comfortable with these operations. The version is now 10.2 and if ordered on the USB flash drive, you can run it there immediately if you don't want to put it on the hard drive..
The program has been maintained and improved frequently. If you have an older version, check with the Change History page to see details on the changes in the program since your version was shipped. The version number is not incremented for small changes, only large ones.
