A trust linked to WeatherTech founder David MacNeil has shelled out about $68.3 million for the oceanfront mansion at 1940 South Ocean Boulevard in Manalapan, the priciest residential sale logged in South Florida this week. Sellers Frank and Dolores Mennella parted with the 2022-built estate, which spans nearly two acres and roughly 16,600 square feet of living space.
Deal details
Public records and market listings peg the deal at about $68.32 million and describe a six-bedroom estate with multiple guest spaces, a beachfront cabana and a private dock. Realtor.com reports the sale closed on Feb. 5, 2026, with the lot at roughly 1.94 acres and the residence at 16,582 square feet.
Price cut and timeline
The mansion first came to market in May at $84.9 million and ultimately closed around $68.3 million after a price chop of more than $16 million, according to The Real Deal. The outlet also reports the sellers hired Luxury Resort Portfolio to list the home, while Premier Estate Properties' Margit Brandt represented the buyer.
Buyer’s local footprint
MacNeil, the founder of WeatherTech, has been quietly building a sizable footprint in Manalapan in recent years, snapping up high-value parcels nearby as part of a broader consolidation strategy. The Wall Street Journal previously reported that he paid tens of millions for adjacent Manalapan lots, a reminder that many buyers at this level rely on trusts and LLCs for privacy and estate planning.
What this means for Manalapan
Industry coverage indicates the deal ranks among the priciest in the small, exclusive town just south of Palm Beach and shows how aggressive list-price cuts are helping push ultra-luxury sales across the finish line. Mansion Global also notes the home sits on a lot once owned by Billy Joel, underscoring the celebrity-linked pedigree of many trophy properties in the area.
The Real Deal identifies the sellers as Frank and Dolores Mennella and reports that Philip Lyle Smith of Luxury Resort Portfolio represented them while Margit Brandt of Premier Estate Properties brought the buyer. The sale underscores how sellers at the very top of the market are trimming ambitious list prices to find the small pool of buyers willing to pay premium cash sums for turnkey oceanfront estates.
