In 1881, the club leased space on Centre Island, and the word "Corinthian" was incorporated into the club's name. In 1887 the organization leased a club house in Manhattan. Finally, in 1891–1892, the club returned to Centre Island, where a new club house was opened, and the club merged with the Oyster Bay Yacht Club.

Recognizing its important history, the Seawanhaka Corinthian Yacht Club was listed on the National Register of Historic Places in 1974.[5]

In 1882, the club adopted a rating rule that would govern all its races:

${\displaystyle Rating={\frac {Load\ Waterline\ Length+{\sqrt {Sail\ Area}}}{2}}}$

Simply known as the "Seawanhaka Rule", it served as a rating for all eastern seaboard races from 1887 onwards, including the America's Cup from 1893 to 1903. The Load Waterline Length was usually placed under a class limit, where any amount beyond the limit was counted double. In the 1893 America's Cup the limit was set at 85 ft, so the Load Waterline Length of an 86 ft yacht would have counted as 87 ft.
