The billionaire founder of WeatherTech is behind another splashy residential deal in South Florida.
David MacNeil sold a 3.6-acre oceanfront assemblage in Manalapan for $105 million, making it the most expensive land sale ever in the Palm Beach County enclave.
The deal signals Manalapan’s ascendancy in recent years. Long overlooked as Palm Beach’s sleepier southern neighbor, ultrawealthy buyers have increasingly turned to Manalapan for its larger estates that provide both beach and Intracoastal Waterway access, a rarity in Palm Beach proper.
MacNeil’s Whiskey Tango 1120 LLC sold the land at 1120 South Ocean Boulevard to HSH-Sunshine Revocable Trust, according to a news release. Margit Brandt with Premier Estate Properties had the listing, and Lawrence Moens with Lawrence A. Moens Associates brought the buyer. The buyer, who is hidden, was also represented by the law firms Mansfield, Bronstein & Stone and Frisch & Frisch, the release shows.
While a record land deal for Manalapan, the sale still falls short of the overall price record for the town, set in 2022 when billionaire Oracle co-founder Larry Ellison paid $173 million for a 16-acre ocean-to-lake estate.
MacNeil has had a busy season of buying and selling luxury real estate across the tri-county region. Earlier this week, he sold a waterfront mansion in Fort Lauderdale for $34 million. In February, he bought the ocean-to-lake Manalapan estate at 1940 South Ocean Boulevard for $68.3 million.
MacNeil, who founded WeatherTech in 1989, has an estimated net worth of $4 billion and a car collection worth $400 million, according to Forbes. He is also a GOP donor and has contributed at least $3 million to President Donald Trump since 2016, according to published reports. In January, Trump tapped MacNeil to serve as chair of the Federal Trade Commission. His appointment has yet to be confirmed.
He acquired the 1120 South Ocean Boulevard assemblage in two deals totaling $94 million in 2024 and 2025. Combined, the lots span 342 feet of direct ocean frontage.
He listed the land for $125 million in December, Zillow shows. The sale marks an 11.7 percent increase in what he paid for the lot.
