Siran is a 63.63-metre Feadship motor yacht built as hull 643 and listed by the yard in its 1991 fleet. Feadship states that the yacht was completed in January 1992, explaining why construction-year and completion-year references can differ. The project is historically significant as the final collaboration between Feadship and designer Jon Bannenberg, an influential figure in the development of the modern superyacht.
Feadship De Voogt Naval Architects provided naval architecture. The shipyard credits Jon Bannenberg and Tim Heywood Design for exterior work and Bannenberg for the interior. At completion, Siran pushed technical and decorative boundaries at the Aalsmeer yard. Feadship highlights the unusually large bonded laminated-glass windows, elaborate exterior stairways, innovative tender handling and a dramatic marble staircase, all developed to create a yacht with a strong architectural character.
The builder's specifications record a length of 63.63 metres, a beam of 10.30 metres and a draught of 3.45 metres. Two Caterpillar 3516 DI-TA engines are listed at 1,119 kilowatts each at 1,600 rpm, with fuel capacity of 130,400 litres and freshwater capacity of 31,000 litres. Feadship publishes an estimated range of 6,000 nautical miles at 13 knots, reflecting the yacht's intended long-distance cruising capability.
Siran has undergone significant updates over her career, with changes made to maintain both engineering reliability and the expectations of subsequent ownership. Feadship's refit record lists work in 2007 including an extension, interior redecoration, an engine-room overhaul, systems updates and repainting. A further programme in 2015 involved a partial repaint, mast-deck extension, changes to crew accommodation and mechanical maintenance.
In 2022, Feadship described the return of Siran to its Makkum facility for another refit, noting the value of retaining access to the yard's specialist engineering expertise. Those successive programmes help explain how an early-1990s landmark yacht remains relevant while preserving the distinctive design ideas that made her notable at launch.

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.
