Sources, assumptions and methodology

Indicative SYG estimate. Value basis: Length-and-age model using length. Central annual OPEX uses the established 14% of estimated yacht value fallback, adjusted for yacht age where available. Low and high cases reflect utilisation, condition, crewing, fuel, berthing and maintenance uncertainty. Capital reserve is shown separately from routine OPEX. Figures must be replaced or upgraded when reported accounts, invoices, court records or other yacht-specific evidence is available.

Calculation version: SYG-FI-1.0 · Last reviewed: 25 July 2026

Financial figures may include reported expenditure, source-derived calculations and indicative estimates. Estimated figures are not audited accounts, quotations or financial advice.

How to read this history: Superyacht Guide estimates, brokerage asking prices and documented transaction values are stored as separate record types. The first baseline record marks the beginning of permanent Superyacht Guide value-history tracking; the absence of an earlier record does not mean the yacht had no earlier market value or sale history.
