    In pre-GPS coastal navigation from my era we had Loran-C, radar, RDF,
    pelorus, gyro-compass, sextant, and the depth sounder.

    Well, most of those tools are obviously still available to the mariner who chooses to use them. RDF is gone, but LORAN is making a comeback. After several years of on-again, off-again funding, debate and deliberation, plans are now going forward to complete an upgrade to LORAN that will allow the system to serve as both a backup and an enhancement to GPS.
