Boathouse Auctions is pleased to announce that STAR DIAMOND, the 154′ Admiral Marine superyacht sold at auction, closed today after a successful auction in partnership with Northrop & Johnson, with the buyer introduced by Denison Yachting. Last asking $8,950,000 USD, STAR DIAMOND sold through Boathouse Auctions’ transparent online auction platform, adding another major superyacht sale to Boathouse Auctions’ growing record of yacht auction results.
The sale reinforces Boathouse Auctions’ ability to work alongside the most respected yacht brokerage firms while creating urgency, visibility, and competitive buyer engagement for superyacht owners. STAR DIAMOND also strengthens Boathouse Auctions’ record with recognized yacht builders, adding an Admiral Marine auction result alongside other recent auction sales involving both motor yachts and sailing yachts.
The sale of STAR DIAMOND adds a notable 154′ Admiral Marine yacht sold at auction to Boathouse Auctions’ growing record of online yacht auction results. Offered from Fort Lauderdale, Florida, STAR DIAMOND attracted attention as a large-volume superyacht with substantial recent investment, exceptional deck spaces, and a highly recognizable story in the charter and television entertainment worlds.
Originally built in 1998 and extensively refit in 2024, STAR DIAMOND represented a rare opportunity for buyers seeking a 154-foot superyacht with meaningful improvements, proven capability, and a defined path to ownership through a structured auction process rather than an open-ended negotiation.
STAR DIAMOND is a 154′ Admiral Marine tri-deck superyacht with 492 GT of volume, accommodations for 10 guests in five staterooms, and crew accommodations for 10. Her scale, flexible guest layout, and expansive exterior spaces made her a compelling auction opportunity in the large-yacht market.
With more than $9 million invested in major mechanical, structural, and shipyard upgrades from 2023 to 2024, STAR DIAMOND offered the refit history and documentation serious buyers look for when evaluating a multimillion-dollar yacht. Her features include Quantum Zero Speed stabilizers with upgraded controls, a Donald Starkey interior, a generous sundeck with Jacuzzi, alfresco dining areas, and a beach-house-inspired interior designed for comfort, volume, and versatility.
STAR DIAMOND is also notable as the ex-OHANA yacht from Below Deck season two, giving the yacht additional public recognition beyond the traditional brokerage audience. For Boathouse Auctions, the sale demonstrates how a high-profile superyacht can be brought to market with urgency, transparency, and professional brokerage collaboration.
The STAR DIAMOND auction was completed in partnership with Northrop & Johnson, with Denison Yachting introducing the buyer. This structure reflects the broker-friendly nature of the Boathouse Auctions model: listing brokerage relationships remain central, buyer-side broker participation is fully supported, and the auction platform adds market exposure, bidder qualification, and real-time online bidding to the traditional brokerage process.
That matters for yacht owners and central listing agents. Boathouse Auctions does not replace professional yacht brokerage. It complements it by creating a defined sale timeline, focusing buyer attention, and giving qualified buyers a transparent path to participate.
The STAR DIAMOND superyacht auction result provides another example of how a scheduled online yacht auction can create urgency for a high-value yacht that might otherwise face an open-ended sales process. In traditional brokerage, distinctive multimillion-dollar yachts can carry ongoing ownership costs while waiting for the right buyer and the right offer. A time-defined auction process changes that dynamic by focusing the market within a clear decision window.
For buyers, the process creates a structured path to review available information, evaluate the yacht, work with brokerage representation, and participate through the platform. For sellers, the process creates a visible market response around qualified buyer interest rather than relying solely on private negotiations over an indefinite timeline.
The sale of STAR DIAMOND demonstrates the value of combining intensive auction marketing, brokerage collaboration, buyer qualification, and a transparent online auction process. When a yacht has a strong reputation, detailed documentation, professional representation, and a clearly defined auction timeline, Boathouse Auctions can help bring serious buyer attention to a decision point.
For owners considering whether to sell a superyacht at auction, STAR DIAMOND is a strong example of how a premium asset can be marketed through respected yacht brokerage channels while gaining the added urgency and transparency of a live online auction.
