Between 1882 and 1886, Munroe returned to Biscayne Bay several times, spending winters with Charles and Isabella Peacock, who were then building the Bay View House, Dade County's first hotel, later renamed the Peacock Inn. He returned to summer in Staten Island each year. In 1886, Munroe decided to make Coconut Grove his permanent home, and purchased the future site of
The Barnacle Historic State Park, which was at the time of bayfront property. He paid $400 in cash in addition to one of his yachts, the
Kingfish, which he valued at an additional $400. Two years later, in 1888, he sold his home in Staten Island to remain year round in Coconut Grove. With his new home began a new life. Munroe built his boathouse directly on the bay in 1887 with living quarters on the upper floor and a workshop on the lower floor. He continued designing yachts, fifty-six of which he completed over the course of his lifetime. His most famous design was
Egret, a 28 ft, double-ended
sharpie lifeboat which he designed for himself. He obtained a wrecking license from the State of Florida to salvage ships on Biscayne Bay, which were numerous due to the surrounding reef and shallow waters. After he had settled into his various careers, the always social Munroe founded the Biscayne Bay Yacht Club in 1887. He was the club's first Commodore, a position he held for twenty-two years. Fully established in every regard but one, Munroe decided to start the construction of his house, "The Barnacle", in 1891. He met his second wife, Jessie Wirth, on a sailing trip in 1894, and they married a year later in 1895. Jessie gave birth to a daughter, Patty, (1900), and a son,
Wirth, (1902) who also became a yacht designer. The family took frequent cruises on the bay and the children learned to sail at a very young age. In 1903, he and his friend Tom Hine established a resort on the property called
Camp Biscayne. Guests included
Ruth Rowland Nichols,
William Grigsby McCormick, and
Alexander Graham Bell. Many who wintered at Camp Biscayne later settled in the area permanently as Munroe had. Munroe's autobiography, ''The Commodore's Story'', was published in 1930. Written with the assistance of Vincent Gilpin, it is one of the few first-hand accounts existing of pioneer days in Miami-Dade County. Munroe was a very good friend of
Captain Nat Herreshoff, America's preeminent yacht designer. Herreshoff spent the last winters of his life residing at a cottage at the Barnacle. Photography was another important aspect of Munroe's life. He was an accomplished amateur photographer. During his lifetime, many of his photographs were used in magazines, newspapers, and books as illustrations. Three illustrations in Willoughby's
Across the Everglades are credited to Munroe. His photographs are the only record of what pioneer days looked like in early Miami. Many of these photographs were published in the book
The Forgotten Frontier. Munroe died on 20 August 1933 at age 82. He was buried in
Sleepy Hollow Cemetery, Concord, Massachusetts. He was survived by his wife and two children who, with his other descendants, continued to occupy The Barnacle until 1973 when the family sold it to the state of Florida. ==Vessels designed==
