According to CNBC, developers and investors are expanding marina-linked luxury real estate as yacht growth contributes to a shortage of boat slips. More than 6,000 superyachts over 30 meters are in service worldwide, with another 200 delivered each year, according to SuperYacht Times. Last year, Blackstone paid $5.6 billion for Safe Harbor Marinas, which paid $1.5 billion in August for 65 marinas and storage sites from MarineMax. Related Group is planning a $2 billion marina development in Fort Lauderdale, slated to break ground next year and open in 2030. The project includes a St. Regis hotel, residences and a marina for 250 boats, with slips for yachts up to 350 feet.
