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.
