Phi delivered from Royal Huisman in late 2021 at 58.5m LOA. She was detained by the UK National Crime Agency in March 2022, held at Canary Wharf for more than two years, and released in 2024 following the successful legal challenge to the detention order. Her return to commercial operation is the most consequential 50-60m news of the 2024-2026 period because the legal precedent her release set has changed the way charter clients should think about flag-state and beneficial-ownership due diligence. We will cover the yacht herself, the case, and what her current operating status means.

Why Phi is the strangest 58m on the water
Two reasons. First, she is a Royal Huisman motor yacht. Royal Huisman, the Dutch yard at Vollenhove, has built its reputation over 140 years on aluminium sailing yachts. Phi is one of the very few full motor yachts they have produced (the sailing-side deliveries dominate the orderbook). The build quality is consistent with Royal Huisman's sailing-side reputation, which is a notable thing in the 50-60m motor class. Most 58m motor yachts come from the Italian or Dutch motor-yacht specialists. Phi came from a sailing yard, and you can see it in the engineering details.
Second, she has a 2.5m higher main-deck headroom than a comparable 58m yacht because she was designed without the constraint of internal cabin volume on the lower deck. The cabin count is 5 (not 6), the guest count is 10 (not 12), and the trade is real: more communal volume, fewer cabins. That trade is the design statement of the yacht and it is the part most charter clients either fall in love with or rule out within the first day on board.
The interior
Lawson Robb's interior is the most architectural in the 50-60m class. The aesthetic is contemporary-minimal with bookmatched walnut, polished concrete, brushed bronze, and an integrated lighting design that treats the cabins as gallery rooms rather than cabins. The main saloon runs the full beam with a continuous glass aft bulkhead. The owner's cabin is on the main deck forward with a private terrace that doubles as a daybed area.
The four guest cabins on the lower deck are unusually large for the 58m class. Two of them are convertible doubles/twins. The dining saloon seats 10 indoors and 14 alfresco on the upper deck. The wellness deck is light (small gym, no spa), which is consistent with the design's focus on communal volume rather than amenity count.
The detention
The chronology, in brief. Phi was berthed at Canary Wharf in London in late February 2022 for owner use. On 28 March 2022 the UK government issued a detention order on Phi under sanctions enforcement powers, citing beneficial-ownership concerns. The yacht was held at Canary Wharf for approximately 26 months. In March 2024 the UK High Court ruled the detention order unlawful on the grounds that the beneficial-owner determination did not meet the statutory threshold for sanctions enforcement, and the detention was lifted.
The case is now a precedent in UK sanctions law for the standard the enforcement authority must meet on beneficial-ownership identification. For yacht-industry purposes, the case is the most-cited recent example of detention-then-release, and it has materially changed the way responsible brokers structure due diligence on charter and brokerage transactions involving complex ownership structures.
Phi spent approximately two years at Canary Wharf without engineering attention, fuel cycling, or crew rotation. Royal Huisman ran a comprehensive post-release inspection at the yard in summer 2024, with a reportedly limited intervention required to return her to commercial-ready status. The yard's view, as publicly stated, was that the build quality was sufficient to handle the prolonged static layup without significant degradation, but the inspection record from that yard visit is not public.
What works on Phi
The build. Royal Huisman engineering is among the strongest in the European yacht industry, and Phi benefits from it. The hull, the welds, the systems integration, the electrical work. By reputation, all of it is at the top end of the 58m class.
The hybrid propulsion. The diesel-electric configuration on Phi allows zero-emission at-anchor operation for periods of and meaningfully reduces noise underway. For an Adriatic or Cyclades itinerary where you will be at anchor most nights, the difference is audible.
The volume. Five cabins for ten guests with full-beam main deck saloons gives a 76 GT per guest figure that is uncommonly generous for the class. The yacht feels considerably larger than her LOA suggests.
The aesthetic. The Lawson Robb interior is a design statement, not a luxury-by-numbers package. For a charter client who has stayed in too many Sinot-or-Reymond-Langton interiors, Phi is a different proposition.
What needs work
The cabin count. Five cabins for ten guests works for some parties and rules her out for others. A six-couple charter party or a four-adult-four-children family group does not fit. The yacht's design is uncompromising on this point and it limits her addressable charter market.
The post-detention provenance. The yacht's history is not her fault, but it is real, and any charter client running a personal due diligence brief will want to satisfy themselves on flag, beneficial ownership, and the status of any residual claims before signing. The current management has, by reputation, been forthcoming on this work, but it is a step that a charter on a yacht with a less complicated history does not require.
The wellness deck. As above. Light. The design priorities on Phi went to communal volume and the architectural interior, and the wellness package paid the price. For a Med charter where you spend most of the day off the yacht, this is acceptable. For a longer charter it is a real gap.
The pricing. Phi is not openly published as a charter rate in May 2026. We have heard that inquiries through her management have produced offers in the €380K to €450K per week range plus 30% APA, which is moderate for the class. But the pricing has not stabilised in a published-rate sense, and a 2026 charter client should expect a more transactional process than a typical 58m booking.
Charter rate and availability
As of May 2026, Phi is not openly listed for commercial charter through the major brokerages. Private inquiries through her management have reportedly produced charter availability in past months. The rate band we have heard is:
- Mediterranean (May to October): €380K to €450K per week + 30% APA + VAT
- Caribbean (December to April): not openly offered for charter
The central agent is. Retail brokers can in principle place a charter inquiry through management. The transaction is not a standard MYBA contract path in May 2026.
Comparable yachts in the class
If Phi's post-detention status or her five-cabin layout is the wrong fit, the closer comparators in the 50-60m class are:
- M/Y Spectre (69m Benetti, 2018): larger, six cabins, more conventional luxury package. See our Spectre profile.
- M/Y Home (50m Heesen, 2017, hybrid): smaller, hybrid propulsion, similar Dutch build philosophy. See our Home Heesen profile.
- S/Y Sea Eagle II (81m Royal Huisman, 2020): the sailing comparator from the same yard. See our Sea Eagle II profile.
Frequently asked questions
Can I tour Phi before chartering? Possibly. Her management has reportedly been open to pre-charter visits at her current base. The visit would be private rather than at a boat show.
Is Phi at boat shows? No. She did not attend Monaco 2024 or Monaco 2025 following her release. We do not expect her at Monaco 2026 based on current planning.
Does the detention affect the charter contract? The standard MYBA charter contract is the same. The due diligence and disclosure expectations are not. A responsible broker will provide more documentation on flag, ownership, and operational continuity than they would on a yacht with a more conventional record.
Is Phi insured for charter? Yes. The post-release inspection and the yard's certification have produced insurance terms that are reportedly within standard market norms.
Can the design be replicated? Royal Huisman has not built a sister hull to Phi. The yard's recent motor-yacht orderbook is light, with the focus on sailing yachts and motor-sailers. A Phi-spec yacht is, as of May 2026, a one-off.
Verdict
Phi is the most interesting 58m yacht in commercial circulation. The combination of Royal Huisman build quality, the Lawson Robb interior, the hybrid propulsion, and the five-cabin volume distribution is unique in her class. The detention history is the part of her record that a charter client must independently evaluate. We are not in a position to underwrite the due diligence work for any individual client, and we will not pretend that the legal context is fully resolved beyond the 2024 release. We can say that her physical condition appears to be intact, her operational status appears to be normal, and her charter availability is real for clients willing to work through a non-standard inquiry path.
If you want a 58m charter with a conventional MYBA contract, a published rate sheet, and a five-broker market for the same booking, Phi is not the easiest answer. If you want a 58m yacht that is genuinely different from the rest of the class, knowingly accept the post-detention provenance, and are willing to do the due diligence work, she is the most interesting choice on the water. The right question to ask the central agent is not the rate. It is the inspection report.
