Coast Guard Island's proximity to a public marina made shipspotting efforts for the USCGC Hamilton relatively easy. Unless the transfer of the USCGC Dallas takes place at the same venue, observation of the transfer at WHEC-176's current home port will present challenges for PN modernization watchers.
Based on the following references, WHEC-716 is based at the Charleston Marine Support Facility.

There is no way to know if the ship below is either the USCGC Dallas or the USCGC Gallatin, which are both stationed in South Carolina. However the Google Earth images below, dated 1989, at least identify the anchorage described above.
