USS YO-144

Under tow in San Diego Harbor on 12 March 1943 shortly after completion by her builder, Concrete Ship Constructors.
The tugs are Narkeeta (YT-133, later YTM-133) on the left and YMT-1 (later YTL-86) on the right. The deckhouse amidships is probably a pumproom.

USS YO-145

Under tow in San Diego Harbor on 14 June 1943 shortly after completion by her builder, Concrete Ship Constructors.
The tug to starboard is probably Wenonah (YT-148, later YTB-148). The stern of Pocahontas (YT-266, later YTB-266) is barely visible to port beyond the barge's rudder.

USS YO-145

Under tow in San Diego Harbor on 14 June 1943 shortly after completion by her builder, Concrete Ship Constructors.
The tug is Pocahontas (YT-266, later YTB-266). The function of the additional deckhouse with the smokestack (absent on YO-144) just forward of the pumproom has not been determined, but it is not for propulsion.
