Superyacht Valuation Calculator & Market Index | Williams Yacht Intelligence

Independent superyacht market intelligence and valuation tool for the 24m+ professionally brokered market. Published by Andrew Williams, marine surveyor with 38 years of industry experience and an MBA from Warwick Business School.

Superyacht Valuation Calculator

Estimate the market value of a superyacht using an independent price model calibrated against 286 motor yacht listings and 79 sailing yacht listings across seven major brokerages. The motor model achieves R²=0.941 — comparable to published residential property indices. Inputs: LOA, year built, builder tier, and performance-open style; from Q3 2026 the ultra-premium tier carries an age interaction. Output: asking price estimate with ±1 standard deviation range and estimated transaction price.

The Williams Superyacht Index — Q3 2026

Q1 2026 established the baseline index of 100.0; Q2 read 100.7; the Q3 2026 edition reads 99.5 (−1.2%), the first decline in the series, measured on 1,908 matched same-vessel asking prices in native currency. The repricing is concentrated below 50m while 50m+ asks hold. Dataset covers 2,382 priced listings from Burgess Yachts, Camper & Nicholsons, Edmiston, Fraser Yachts, Y.CO, Denison Yachting, and Moran Yacht & Ship. Model-sample fleet value: motor €7.4bn + sail €0.95bn = €8.4bn asking.

Key Model Findings — Q3 2026

• LOA elasticity 2.85 (motor): a 10% increase in length is associated with approximately 31% higher asking price.
• Ultra-premium builder premium (e.g. Feadship, Lürssen, Oceanco, Abeking & Rasmussen): +44% at new, growing with age to about +86% at twenty years — Q3 2026 measures that Tier 1 hulls depreciate ~1.3 points a year more slowly (t=2.8 on the age interaction).
• Premium tier (e.g. Amels, Heesen): +44% over market baseline (t=7.1, p<0.0001).
• Mid-tier builders (e.g. Benetti, Sanlorenzo, Perini Navi, Codecasa, Icon, Royal Huisman, Palmer Johnson): +15.7% over market baseline (t=3.3, p<0.001).
• Performance-open flag: fast planing yachts without a flybridge (e.g. Mangusta, Pershing) carry +15% when new, eroding at roughly 3.3% a year faster than the fleet (t=−7.0).
• Annual depreciation: approximately 6.9% per year from new, decelerating with age. New for Q3 2026: ultra-premium hulls depreciate measurably more slowly than the other tiers.
• Asking-to-transaction discount: 15%, as established from 61 superyacht transactions 1999–2006 (Williams 2007, Warwick Business School).
• LOA elasticity 2.32 (sail, monohulls only): a 10% increase in length is associated with approximately 25% higher asking price.

Superyacht Depreciation Analysis

Empirical depreciation curves derived from the hedonic model show approximately 6.9% annual value loss from new, decelerating with age. From Q3 2026 the ultra-premium tier carries its own age interaction — Tier 1 hulls shed value about 1.3 points a year more slowly, so the builder premium grows over a vessel's life.
