On March 27, 1951, the clubhouse was relocated by barge to its present site at the foot of Qualtrough Street. By 1954, the Club signed a 5-year lease with renewal options and committed to developing a Penguin Fleet for Junior Members. The Club grew to 250 members by 1955, the construction of a fifth dock began, and an electric hoist was installed. In 1958, the Clubhouse was remodeled, adding much needed space.
In 1964, SWYC hosted the inaugural San Diego to Ensenada Race with 55 boats, a race that continues today.
In 1966, a new fleet of yachts was formed called the "Coronado 25 Class" and quickly became the largest one design fleet in SWYC. The Club also hosted the 1970 Coronado 25 World Championship with 35 entries from all yachting areas as well as an entry from France.
A new 40-year lease with the Port District was secured in 1969. The new Clubhouse and the "L" shaped building housing lockers, maintenance, the heads and showers were completed in 1972 along with a new seawall. With a membership of 400, Southwestern Yacht Club prepared for events to commemorate their Golden Anniversary in 1975.
To commemorate SWYC's 50th Anniversary, a special emblem was selected. The celebration was attended by Mayor Wilson, who was honored with a key to the Yacht Club. This event boosted membership and garnered significant publicity, and, in November 1975, the club upgraded A and B docks, adding 92 slips and starting a slip waiting list that remains active today.
SWYC began sponsoring the Muscular Dystrophy Charity Bay Race in 1983, and thus started an annual series of events to raise money for charities. SWYC has raised nearly $2,000,000 for local charities. During the 1992 America's Cup, SWYC hosted the Louis Vuitton CSS, with Team New Zealand’s Black Magic winning in 1995.
A Dock Replacement Committee was formed in 1990, and all docks were replaced by 1993.
SWYC won the prestigious Sir Thomas Lipton Cup in 2003, and again in 2008. US Sailing awarded its prestigious trophy for Race Management, the St. Petersburg Yacht Club Trophy, to Southwestern Yacht Club "for its outstanding organization and execution of the 49er Olympic Trials from October 3-14, 2007."
Southwestern Yacht Club’s new clubhouse opened in 2010, with 784 members and active programs in Sailing, Angling, Cruiser Navigation, Cruising, Juniors, and Social Functions. Southwestern Yacht Club looks forward to its Centennial Celebration in 2025.
