Matteo Russo, 36, and his father-in-law John Orlando, 58, died when their 54-foot vessel, the Patriot, sank so quickly that neither man had time to grab a life-saving device or send out an emergency signal, and that sinking occurred when the ship lost stability and capsized, according to the report, which was made public Friday.

Coast Guard Captain John Healey said Friday that underwater acoustic equipment captured a series of "loud bangs" on the Patriot in the moments leading up to the sinking, which could suggest a loss of stability due to flooding.
