Ashbury was appointed commodore of the
Royal Harwich Yacht Club in 1870, having been elected a member in 1867. He made the first two, albeit unsuccessful challenges for the
America's Cup, held since 1851 by the
New York Yacht Club. Ashbury's first challenge was in 1870 with his yacht
Cambria. The race for the America's Cup was held on 8 August, and
Cambria faced 14 yachts of the New York Yacht Club. The race was won by the
Magic, with the
Cambria finishing in eighth place. Returning to England, Ashbury commissioned a new yacht
Livonia. Ashbury took his new yacht across the Atlantic to once again challenge for the America's Cup, this time on behalf of the
Royal Harwich Yacht Club. Controversial from the start,
Livonia was defeated 4–1. He returned to the United Kingdom without the trophy accusing the New York Club of engaging in "unfair and unsportsmanlike proceedings". The club responded by returning a number of trophies he had donated in the previous year. Although the event ended in acrimony, Ashbury was the catalyst for the introduction of greater fairness in no longer allowing the defender to use multiple yachts against a single challenger, and was belatedly inducted into the
America's Cup Hall of Fame in 1997. ==Member of parliament for Brighton==
