Graycliffs is a 33.65-metre Feadship motor yacht delivered in 2016 as Moon Sand Too, hull 691. She was conceived as one of three smaller, shallow-draught Feadships intended to retain Feadship construction quality while allowing access to cruising grounds and moorings that can be restrictive for larger yachts. Naval architecture is by Feadship De Voogt Naval Architects, exterior design is by Studio De Voogt and the interior is by Bannenberg & Rowell Design. Feadship's original fleet archive records a 7.75-metre beam, 1.80-metre draught, twin MTU 12V 2000 M93 main engines rated at 1,340kW at 2,450rpm, twin Kohler 70EFOZDJ generators, 24,600 litres of fuel, 5,400 litres of fresh water and a 3,000-nautical-mile range at 10 knots. Accommodation is for eight guests in four staterooms. Renamed Graycliffs, she was sold to an American owner in August 2026 through a Joint Central Listing by Feadship Resale and Edmiston; the final sale price was not disclosed.

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.
