Off the shores of Miami, a growing number of smaller boats are being left abandoned in Biscayne Bay, overshadowed by the influx of super yachts owned by the city’s expanding billionaire population. Since October, Miami Beach police have identified and removed approximately 140 derelict vessels from the bay, with others remaining partially submerged or tethered near some of the most expensive waterfront properties in the United States.
Sergeant Javier Fernandez, commander of the Miami Beach police marine unit, highlighted the challenges posed by these neglected boats. Speaking from the department’s patrol vessel near Star Island, Fernandez pointed out a sunken 30-foot cabin cruiser deteriorating in shallow waters. “A lot of people buy a boat but don’t realize how much it costs for fuel, maintenance, and marina fees,” he said, indicating that many owners underestimate the ongoing expenses involved in boat ownership.
The increase in abandoned craft is part of a broader surge in boating activity fueled by demographic shifts since the onset of the COVID-19 pandemic. Miami has seen a significant influx of wealthy newcomers, driving demand for larger, more expensive boats and straining marina capacity and maintenance services. In 2024, Florida recorded roughly 1.2 million registered boats, the highest in the nation, reflecting a 20 percent rise compared to the previous year, according to the National Marine Manufacturers Association.
The types of vessels left unattended vary widely, including sailboats, cabin cruisers, pontoon boats, center-console fishing boats, bow riders, and even a 60-foot custom catamaran, according to police records. These abandoned boats pose navigational hazards and environmental risks, sometimes breaking loose from decayed moorings and colliding with seawalls near luxury residences. Fuel leaks from deteriorating vessels add to environmental concerns.
The situation on Biscayne Bay mirrors broader patterns of gentrification impacting Miami’s land and waterways alike. The city has witnessed substantial real estate investment by affluent individuals, leading to a 36 percent increase in the cost of living over six years—outpacing the national inflation rate of around 29 percent for the same period, based on data from the Bureau of Labor Statistics. This economic pressure has forced some long-time residents to relocate; a study by the Bank of America Institute found Miami to be the U.S. city with the highest net out-migration.
As the cost of boat ownership continues to rise alongside living expenses, many smaller boat owners find themselves unable to maintain their vessels, resulting in a growing marine “graveyard” that reflects the shifting socioeconomic landscape of South Florida’s coastal communities.
