ORC and X-Yachts Joint Update on XR41 and VPP
Alexandra
ORC will present verified analytical results and any proposed adjustments to the 2026 VPP to the ORC Congress, the official body that approves rating changes; that regulatory timetable anchors the current technical work on the XR41 and sets the path for implementation across race fleets and charter-rated yachts.
Current coordinated technical process
ORC and X‑Yachts have launched a structured, multi-method review focused on ensuring the VPP remains a scientifically robust rating tool. The collaboration centers on the XR41's observed performance relative to the modelled outputs and on the formal limits embedded in the ORC VPP parameter set for 2026.
Core activities underway
- Joint review of observed performance data: measured race logs and in-service telemetry are being compared directly against VPP predictions to identify consistent offsets in speed or polars.
- Additional CFD studies: computational fluid dynamics analyses are being contributed by X‑Yachts’ naval architect Tobias Merkel to refine hull and appendage flow models.
- Independent analysis: third-party experts, including consultancy KND, are conducting validation runs to provide impartial verification.
- ANN-domain mapping: systematic mapping of artificial neural network coverage is identifying structural gaps where the model behavior may be extrapolating beyond its validated domain.
- Parameter evaluation: current limits in the VPP parameter set are being examined for scientific justification and will be adjusted only where validated evidence supports change.
Why these steps matter
A rating system such as the ORC VPP is a computational representation of yacht performance. Changes that are not grounded in transparent, replicable science risk introducing bias—affecting not only race fairness but also charter ratings, sale valuations, and owner decisions on modifications or new builds.

Governance, transparency and impartial adjudication
The joint statement emphasizes that any VPP modification must be data-led and methodologically transparent. Both organizations underline the role of a balanced and impartial ITC, supported by governance safeguards against conflicts of interest, and by open communication in rule development.
Principles reiterated
- Scientific integrity: the VPP must remain a scientific model — updates will be validated, documented, and publicly explained.
- Transparency: ORC will publish a full technical explanation of background, findings, and implications once the analysis is verified.
- Fairness: adjustments cannot be driven by single regatta results or stakeholder pressure; they must be repeatable and evidence-based.
Timeline and delivery
The work is being prioritized; once verified results are available, ORC will circulate detailed technical reports and present any recommended actions at the ORC Congress for approval. That governance checkpoint ensures rule legitimacy before any field application in the 2026 season.

| ORC Congress review | ORC Congress | Approve any changes | Decision on 2026 VPP |
Implications for yacht owners, charter operators and sailors
Adjustments to a VPP affect more than race results. A revised rating can influence how a yacht is presented on the charter market, its handicap in club racing, and owner choices about sail inventories or appendage changes. Charter operators and brokers should monitor the ORC announcements closely as rating changes can alter competitive matchups and booking decisions for race charters and regatta-week clients.
Practical points for the charter sector
- Listing accuracy: charter platforms and owners need up-to-date ratings and polars to present fair expectations to renters.
- Refit planning: owners contemplating changes should weigh potential VPP consequences before investing in major modifications.
- Race charters: charterers seeking competitive experiences will want vessels with clearly validated performance data.

What to watch next
The immediate milestones are completed CFD deliverables, independent verification statements, and publication of the ORC technical explanation. Sailors, designers, and charter managers should expect transparent documentation before any rule changes are enacted for 2026.
Key highlights of this process include the use of multi-method validation (field data, CFD, and third-party review), the explicit mapping of ANN model coverage to avoid extrapolation errors, and a governance path that routes decisions through ORC Congress to maintain credibility and fairness.
If you are planning your next trip to the sea, you should definitely consider renting a boat (boat rentals, rent a boat, rent a yacht), as each inlet, bay, and lagoon is unique and tells you about the region just as much as the local cuisine, architecture, and language — experiencing a new location is always a multifaceted process, where one learns about the culture, nature, the indescribable palette of local colors its rhythm of life and also the unique aspects of the service.

Forecast: this technical review is regionally important to fleets racing against the XR41 and to markets where XR41s participate in charter or sale activity; its global tourism impact is limited but relevant to niche regatta circuits and charter communities. However, it remains significant to customers—GetBoat aims to stay abreast of developments and keep pace with the changing world. If you are planning your next trip to the seaside, consider the convenience and reliability of GetBoat.
Summary: ORC and X‑Yachts have committed to a transparent, evidence-based review of the XR41 and the ORC VPP parameters for 2026, combining on-water data, CFD work by Tobias Merkel, independent analysis by KND, and ANN-domain mapping to ensure any changes are scientifically justified. This process protects fairness in racing and maintains confidence for owners, charter operators, and buyers. Whether you are looking at a yacht for charter, sale, or private use, platforms like GetBoat provide global, user-friendly access to listings that include make, model, ratings, and transparent details, helping you plan unforgettable experiences on the sea. Embrace the freedom to choose — book your next charter or explore a sale with confidence, and let reliability and transparency guide your course.
