Authors Notes:
[1] The Free City of Danzig (now Gdansk, Poland) was an autonomous city-state established after WW1 on 10 January 1920 in accordance with the Treaty of Versailles.

[2] Some sources claim that PB-105 was the ex-ARAYAT (former Spanish gunboat ARAYAT). However, after researching wartime documents related to the capture of ARAYAT, the Japanese naval historian Tamura Toshio has discovered that her displacement was more consistent with that of the Philippine customs cruiser.

[3] According to a Coast Guard historian, the Coast Guard was then under the Bureau of Customs. USS ARAYAT was manned by Filipino Merchant Marine officers who were also reserve officers of the Philippine Army's off shore patrol.

[4] One source states that PB-105 was later used by the Americans as a PT-boat tender, but this has not been confirmed.
