From 1870 until 1920, the America's Cup races was held in Lower New York Bay, off Sandy Hook. In 1899, Guglielmo Marconi placed an
antenna and receiving station at the
“Twin Lights� Navesink Light Station to demonstrate his Wireless Telegraph. The New York Herald
newspaper had hired him to report on the America’s Cup yacht races which were being held off the tip of Sandy Hook, the first use of wireless
telegraphy on a commercial basis. The defending yacht for the New York Yacht Club was
Columbia, designed by the famous Nathanael Greene
Herreshoff. The challenger yacht was
Sir Thomas Lipton's first Shamrock. The America's Cup races were sailed from October 16 to 20, 1899, in
the best three out of five. There were three different courses: the first one, 15 miles to leeward and return from Sandy Hook Lightship; the second
one, an equilateral triangle of 30 miles; the third one, 20 miles to leeward and return from Sandy Hook Lightship. In the first race on  October 16,
Columbia beat Shamrock by 10 minutes and 08 seconds on corrected time. In the second race on October 17, Columbia won after Shamrock
withdrew after breaking its topmast. In the third race on October 20,
Columbia beat Shamrock by 06 minutes and 34 seconds on corrected time.

Columbia went on to defend the cup again two years later against the much newer Shamrock II in a best of five race series from September 28 to
October 4, 1901. Again three deferent courses were run, and once again the results were Columbia over Shamrock II three wins to nil. The first
race on September 28, 30 mile windward-leeward course from Sandy Hook Lightship, was won by Columbia by one minute and 20 seconds on
corrected time. The second race on October 3, a 30 mile triangular course, Columbia beat Shamrock II by three minutes and 45 seconds on
corrected time. The third race on October 4, a 40 mile windward-leeward course, Columbia beat Shamrock II by 41 seconds on corrected time.
Columbia made America's Cup history as the first boat to win the trophy two times in succession.
