Billionaire hedge-fund founder and philanthropist Ken Griffin's Private Megayacht Marina Gets Green Light and he is doubling down on his South Florida waterfront portfolio, this time with a private, resort-style megayacht marina built just for himself and his guests. The proposal, which recently cleared key regulatory approval, offers a fresh lens into the rising intersection of luxury real estate, deep-water berthing, and exclusive yacht infrastructure in the Miami market.
Project Overview
Griffin’s affiliate has filed plans for a 30,000+ square-foot facility at 120 MacArthur Causeway on Terminal Island (Miami Beach), a 3.7-acre waterfront site with approximately 1,400 ft of dockage along one of Miami’s rare deep-water corridors.
The program, designed by BMA Architects, includes:
A secured gatehouse/check-in pavilion.
A crew pavilion featuring kitchen/laundry, staff gym, sauna, showers, changing rooms and a modest rooftop pool.
An owner’s pavilion with lounge/office/storage and a private pool.
Marina operations building including repair shop, offices and support functions.
Slip capacity targeted for large superyachts (Griffin owns a 308-ft “Viva”).
Status & Regulatory Context
On Nov 4-5, 2025, the Miami Beach Planning Board approved the conditional use permit for the development, subject to conditions such as Coast Guard sign-off for special events, non-public access, dedicated on-site parking, and a mandatory return to the board if ownership changes. Griffin’s team described the project as a long-term investment in improving an industrial waterfront site.
Why This Matters for the Yacht & Waterfront Market
Deep-water scarcity meets trophy capital. Miami’s waterfront berthing for megayachts is finite. A project of this scale and exclusivity signals how high-net-worth buyers are seeking infrastructure solutions tailored to their fleet’s size and lifestyle.
Blending real estate + marina assets. For your clients looking at waterfront homes with docks: this development makes a clear statement, beyond the residence, the adjacent deep-water berth and amenities are prestige assets in their own right.
Re-imagining industrial waterfronts. Terminal Island is comprised mostly of maintenance, utility and ferry uses. Converting a 3.7-acre industrial parcel into a fully gated intimate marina sets a precedent for repurposing under-utilised waterfront land in mixed-use luxury markets.
Event and lifestyle orientation. Although the marina is for Griffin and his guests, filings suggest occasional special-event use (e.g., during Miami Grand Prix or Art Basel Miami Beach). This indicates how yacht infrastructure is transforming toward hospitality-grade amenities rather than strictly berth storage.
Implications for Your Brokerage & Client Advising
For buyers of trophy homes with docks, this reinforces the notion that owning a premier berth (or access to one) is now a differentiator, not just a convenience.
For sellers, being able to reference the upward trajectory of deep-water berthing supply (or lack thereof) can support premium pricing.
For developers/waterfront land investors, this project underscores a shift: superyacht-scale infrastructure, exclusive use, highly serviced crew amenities — think gym, sauna, rooftop pool — all of which add to cost basis and value proposition.
For charter investors, while this is a private marina, the trend toward ultra-luxury marina infrastructure supports broader charter-friendly waterfront ecosystems (crew welfare and deep water access being key).
What to Watch Next as Ken Griffin’s Private Megayacht Marina Gets Green Light:
Building permit timeline: When Griffin’s team obtains full construction permits, it will likely trigger announcements from lenders and contractors.
Slip leasing / guest-use policy: Although exclusive, any ancillary guest-use or event policy (even limited) may raise new regulatory or community concerns.
Marine infrastructure ripple effects: Potential competitor marinas, or developers of waterfront residential communities, may accelerate upgrades to match emerging bespoke standards.
Impact on waterfront land values: The repurposing of Terminal Island may inspire adjacent parcels’ re-zoning or redevelopment momentum.
For the yacht-brokerage and waterfront-homes community in South Florida, Ken Griffin’s planned private megayacht marina is more than headline-grab: it’s a marker of where the luxury waterfront market is headed. It blends ultra-deep-water access, lifestyle amenities, crew facilities and real-estate scale into what amounts to a high-net-worth bespoke marina enclave.
If you work with clients seeking trophy berthing, waterfront estate with dock rights, or waterfront land with development potential, this is a story worth telling—and one your audience should understand.
