Now at Port Vila, Vanuatu. Reported South African flag and MMSI 601767000, but apparently still using Panama call/sign HO3793.

I have the operating instructions that were issued with this ship when she was built, then they applied to the following FP 176' Steel Supply Vessels, FP 253-294, FP 309-309, FP 343-356, FP 361-374, FP 381-411, FP 414-415, FP 524-529 and FP 546-550. If any body has any shots of her they'd like to share please contact me, we just shot an oral history of her last Chief Engineer. This vessel was in the 144th Transportation Battalion at the Port of Tacoma from 1964 until 2008.

Apparently she was the scene of a fatal accident in Fiji earlier this year - see http://fijione.tv/investigators-still-not-allowed-on-betsy-ross-vessel/ and http://fijisun.com.fj/2015/03/13/betsy-ross-probe-starts/
