Manalo was introduced to diving at age 16 by Jack Lavery. It was Lavery who introduced her to Phil Patterson, swimming coach of the Fairmont Hotel Swimming and Diving Club. Due to racial discrimination and prejudice for being a Filipino, she changed her name to Vicki Taylor to be accepted in Patterson's school. Patterson's military stint during World War II caused Manalo to stop diving for a year. She instead found a job at the Presidio military base. Manalo later joined the swimming program at the Crystal Plunge in North Beach headed by Charlie Sava and was assigned Jimmy Hughes as her coach. Her 50–100 dives after-school diving practice continued even to her enrollment at San Francisco Junior College (now City College of San Francisco). At age 19, Hughes guided her to a third-place finish in her first national AAU diving competition at the Indiana national meet in 1943.
