Does anyone know if Seaclear II or any of the other "free" or cheap computer navigation programs provides a means of having an anchor alarm. I use Nobeltec's Max Pro software and it works fine, however, it requires a dongle. As a back up for when the dongle breaks I use the free software that comes with the CYC charts, however, it does not have an anchor alarm. Marty Campanella Bay Pelican KK42
