- 3Fixed prices of auf Anfrages or auf Anfrages ensure full cost transparency with no hidden fees.
Tuesday, 10:00 a.m., a marina in Berlin-Wannsee. A 12-meter sailing yacht lies at the jetty, waiting to be inspected ahead of a planned private sale. The prospective buyer needs certainty about the condition of the GRP hull and the functionality of the onboard electronics, while the seller wants to substantiate a fair market value. This is where the mobile surveyor from DIAVAG comes in. Without the boat having to be laboriously relocated or craned out, the technical inspection takes place directly on site. This standardized process safeguards the independence of the valuation and creates a robust data basis for both contracting parties.
The Importance of Independence in Boat Valuation
In the maritime industry, the independence of the surveyor is the highest good. Many market participants simultaneously act as brokers or insurance intermediaries, which can lead to potential conflicts of interest. DIAVAG positions itself strictly as a neutral service provider. The company does not sell boats, does not broker insurance, and does not carry out repairs. This separation of trading and inspection interests is the fundamental prerequisite for the recognition of the valuation reports by banks, insurers, and in legal disputes such as inheritance or divorce cases.
The qualification of the surveyors follows the guidelines of the BVSK (German Federal Association of Freelance and Independent Motor Vehicle Surveyors). In addition, DIAVAG operates according to the ISO/IEC 17020 Type A standard, which represents the highest level of independence for inspection bodies. For customers, this means that the delivered PDF report is not merely a subjective opinion, but is based on a standardized inspection procedure that is finally signed off by a senior inspector. For specific legal questions, customers should always consult a specialized lawyer or notary, as the surveyor exclusively provides technical and value-relevant facts.
Mobile Service at the Mooring and in Winter Storage
A key advantage of the DIAVAG model is mobility. Traditional valuations often require the asset to be brought to an inspection station. For sailboats, this involves considerable logistical effort and cost. Instead, the DIAVAG surveyor comes directly to the boat's location, whether at a marina, in a boat storage facility, or on a trailer in winter storage. This service is available in the regions of Hamburg, Berlin, and Munich within 24 hours of booking an appointment. Nationwide rollout is planned for 2026.
On site, the surveyor needs less than 15 minutes for the physical inspection, provided all relevant areas are accessible. Through the use of calibrated hardware and a specialized software app, the condition of the sailboat is documented comprehensively. The time savings for the owner are considerable, since no transport trips or crane appointments need to be coordinated. The result of the inspection, a legally sound PDF report, is delivered digitally the same day. This speeds up sales processes and enables prompt clarification of insurance matters.
Technical Inspection Points and Hardware Used
The inspection of a sailboat by DIAVAG follows a strict protocol to capture all value-determining factors. A standardized hardware case is used, which includes, among other things, a coating thickness gauge. This can identify repaints or repairs to the hull that may indicate previous collisions or groundings. For steel yachts, measuring the material thickness is also essential for assessing the risk of corrosion.
Another focus is on the drive unit and the onboard electrics. If the boat has a modern inboard engine with an appropriate interface, an OBD2 scanner is used to read out fault memories and check operating parameters. The electrical systems are examined with a digital multimeter for voltage stability and correct fusing. The sail wardrobe, the rigging, and the safety equipment are also included in the assessment. The entire documentation is supplemented by a tamper-proof photo set that unequivocally proves the condition at the time of inspection. Optionally, the report can be secured with a notarial hash on the Polygon blockchain to guarantee maximum protection against forgery.
Transparent Fixed Prices with No Hidden Costs
Pricing in the surveying industry is often opaque and dependent on hourly rates or the value of the object. DIAVAG breaks with this practice and offers a fixed-price model for sailboats. The standard report for private customers costs auf Anfrages. This price includes travel within the regions, the on-site inspection, and the preparation of the BVSK-compliant report. For particularly high-value assets or yachts with complex systems, the premium variant is available for auf Anfrages.
This model provides planning certainty for buyers and sellers. There are no hidden fees for documentation or for sending the digital report. For commercial customers, such as charter fleet operators or boat dealers, who reach a volume of more than 50 reports per month, individual terms are agreed. These B2B customers also benefit from an API connection to their dealer management systems (DMS), which automates the integration of the reports into existing sales processes. Independent surveyors also have the option of purchasing the standardized hardware case, including the software, for a list price of auf Anfrages to become part of the DIAVAG network.
Comparison of Surveying Services
To clarify DIAVAG's positioning, a comparison with other market participants is worthwhile. While classic inspection organizations such as TÜV or DEKRA focus almost exclusively on the passenger car segment and rarely offer specialized boat valuation reports, DIAVAG covers a total of seven asset classes. Unlike pure online estimation services, DIAVAG always carries out a physical inspection by a qualified surveyor.
| Feature | DIAVAG | Vehicle inspection stations (TÜV/DEKRA) | Online estimators |
|---|---|---|---|
| Mobile service | Yes, at the mooring | No, stationary | No inspection |
| Boat asset class | Yes, specialized | Usually not | Partially (data-based) |
| Fixed price | auf Anfrage / auf Anfrage | According to fee schedule | Often free/inaccurate |
| Legal validity | BVSK / ISO 17020 | Only for vehicle inspection | Low |
| Processing time | 24h appointment / PDF same day | Appointment-dependent | Instant (algorithm only) |
This comparison shows that DIAVAG closes the gap between purely algorithmic valuation and often hard-to-access, high-priced specialist appraisal. The combination of mobility, technical depth, and legal usability makes the service an efficient solution for the maritime secondary market.
Occasions for a Sailboat Valuation Report
There are numerous situations in which a professional valuation report is indispensable. In a private purchase or sale, it serves as an objective basis for negotiation and protects against unpleasant surprises after the transaction. Insurers often require a current report to determine the replacement value, especially for older yachts or after extensive modernization. In the event of damage, the report forms the basis for settlement by the insurer, whereby DIAVAG only provides the technical facts and the final decision rests with the insurer.
Documentation also plays a central role in a legal context. In cases of inheritance or divorce, the real market value of a sailboat must be determined to enable a fair division of assets. Here, the reference to the JVEG (Judicial Remuneration and Compensation Act) applies, as BVSK-compliant reports enjoy high acceptance in court. Another important aspect is charter return. Charter fleet operators use the standardized inspection to document the condition of their vessels after the season and to assert any defects in a legally sound manner against the customer or the insurer.
Future Readiness and Regulatory Standards
The requirements for documenting technical assets are steadily increasing. DIAVAG is already preparing today for upcoming regulatory requirements, such as the EU Battery Passport, which becomes mandatory from February 2027. This is particularly relevant for sailboats with electric propulsion or large lithium-ion storage capacities for onboard power supply. The DIAVAG Premium Battery Test already provides detailed data on state of health (SoH), cell balance, and actual capacity.
Compliance with GDPR and data storage on servers within the EU are a matter of course for DIAVAG. This guarantees customers that their sensitive vehicle and personal data are processed to the highest security standards. By combining traditional surveying expertise with modern digital infrastructure, DIAVAG offers a solution that meets both today's requirements for speed and transparency and future legal frameworks. Independence always remains the core of the business model, in order to preserve the integrity of every single report.
