"The APC 3, third of its class to be completed at the Herreshoff Mfg. Company for the U S Navy, will be launched tomorrow at 10 a. m at the lower yard.
Miss Margaret Louise Hibbert, the daughter of Mr and Mrs. George Hibbert, 240 Hope street, will be the sponsor. Her father is the foreman of the cabinet shop at Herreshoffs and is a long-time employee of that company. Mr. and Mrs. Hibbert have two sons, both of whom are in the Navy.
The selection of Miss Hibbert to act as sponsor of the APC 3, was made as the result of a policy adopted recently by the Herreshoff Mfg. Company. A drawing by lot is made among the foremen, principal men and resident naval inspectors, and the wife or daughter of the winner becomes the sponsor of the ship to be launched.
The APC 3 is a special task naval vessel of which several are under construction at the Herreshoff yards." (Source: Anon. "Launching Tomorrow At Herreshoff's At 10 A. M." Bristol Phoenix, August 25, 1942, p. 1.)

"The launching of the APC 4 will take place tomorrow [August 29, 1942] at 9 o'clock at the lower yard of the Herreshoff Mfg. Company.
Mrs John Millar, wife of a construction foreman at Herreshoff's, will be the sponsor of the APC 4. Co-sponsors will be her two daughters, Barbara and Jane.
This marks the fourth of the special task naval vessels, known as the APC type, to be launched at Herreshoff's.
The APC 3 was launched Wednesday [August 26, 1942] morning with Miss Margaret L. Hibbert, daughter of George Hibbert, as sponsor." (Source: Anon. "APC 4 To Be Launched At Herreshoff's Tomorrow." Bristol Phoenix, August 28, 1942, p. 1.)

"Twenty-two of these 'jacks of all trades' were built between October 1942 and July 1943 --- with an average of nearly one of these 103-footers each week. Each cost $145,750, and they appear to have been contracted for in two batches, with the lead ship [#425p] of the class (APc 1) included in the first batch of ten; APc 85 [#500p] through APc 96 [#511p] constituted the second batch. It was an impressive rate of production, especially so because the APcs were built concurrently with eight 71-foot British Vosper torpedo boats, which were built in the South Construction Shop."

Note: The transcription of the HMCo Construction Record by Peter Vermilya and Maynard Bray was performed independently (and earlier) than that by Claas van der Linde. A comparison of the two transcriptions can be particularly useful in those many cases where the handwriting in the Construction Record is difficult to decipher.
