Born in Philadelphia, Mr. Flood graduated from Central High School in 1945 and, after a year in the Navy, earned a bachelor's degree in economics at Lafayette College in 1950.
Mr. Flood spent his career at what was then Philadelphia National Bank, beginning in 1950 and retiring as a senior vice president in 1988, his wife said.
He began in the corporate finance department, traveling in Southern states to help PNB make loans to smaller banks.
Later, he was put in charge of the bank's branches in the Philadelphia suburbs, his wife said, and finally he helped the bank finance corporations in the Philadelphia region.
Mr. Flood competed in four Newport Bermuda Races, run by the Cruising Club of America and the Royal Bermuda Yacht Club, as part of a crew for which he often worked as a watch captain.
He was a crew member on the same boat on races from Marblehead, Mass., to Halifax, Nova Scotia.
Mr. Flood owned what his wife said was a 36-foot Pearson, on which he raced for the Corinthian Yacht Club of Philadelphia and the similarly named club of Cape May, in events on the Chesapeake Bay and off the coast of New England.
He was the Philadelphia club's commodore in 1985 and 1986.
It wasn't all competitive. "We used to take vacations and sail up to Maine," his wife said.
His initiation to the sea progressed rapidly beyond the converted rowboat, she said.
When he was 12 and "because he was such a good sailor," his wife said, his father had someone design for the boy "a single-sail, one-person boat, around 11 feet long," a Moth boat.
"After the Moths, he sailed Comets," which are longer boats, "into his 20s. I crewed for him on the Chesapeake."
Mr. Flood was a deacon and elder at Bryn Mawr Presbyterian Church and a member of the Union League and the Merion Cricket Club.
Besides his wife, Mr. Flood is survived by daughters Susan Thorkelson and Nancy Smith, five grandchildren, and a great-grandson.
A memorial service was set for 2 p.m. Thursday, Sept. 13, at Bryn Mawr Presbyterian Church, 625 Montgomery Ave., Bryn Mawr. Burial is to be private.
