The Steamship Authority port captain has resigned, boat line general manager Robert Davis confirmed this week.

Capt. Greg Gifford, 64, who has served as port captain since 2004, will retire next month, Mr. Davis said.

The port captain oversees vessels and crew, including 60 licensed deck officers, and acts as a liaison with the Coast Guard. The management position is a non-union job. Captain Gifford’s salary in 2017 was 108,669.60, according to boat line payroll records.

Mr. Davis could not say whether Captain Gifford’s retirement is connected to the recent turmoil at the boat line.

“He indicated at this stage of his life that he wants to spend more time with family,” the general manager said.

Mr. Davis said Mr. Gifford, who lives on the Cape, has an unlimited master’s license and formerly sailed all over the world.

He said the assistant port captain, Capt. Charles Monteiro, will become port captain in the interim.
