100m+ Yachts for Sale

Two yachts of the same length can feel completely different on board. Gross tonnage (GT) measures enclosed internal volume — it is not weight, and it is not displacement. At 100m+, GT is often a better guide than length to living space, crew areas and running costs.

• GT = enclosed volume; displacement = weight of water displaced
• At 100m+, volume commonly starts around 4,000–5,000GT, and the largest yachts exceed 10,000GT
• Higher tonnage generally means larger crew, more demanding certification and higher running costs, depending on flag and use
• A high-volume 105m can exceed a low-volume 120m
• Only the yacht's tonnage certificate is reliable — never a brochure figure
• We show GT only where the yacht's documents support it

This is general information, not legal or regulatory advice. Confirm the requirements for a specific yacht with its flag, class society and a qualified adviser.

Build type is one of the biggest differences between yachts of similar length. It shapes how easily a yacht can be compared, how it holds value, and what can be changed.

• Series: a defined model with limited options — the easiest to compare against sisterships
• Semi-custom: a proven hull and engineering platform with tailored layout and interiors — builder programmes exist around 100m+, but many yachts here are full custom
• Full custom: designed for one owner; the majority of this band, from Northern European and Mediterranean yards and harder to benchmark
• Model number ≠ actual length: always compare length overall, not the name
• One model name can span several generations with different hulls, engines and layouts
• Factory options and later refits shape value as much as year

Every 100m+ yacht is run by a professional captain and crew, and the way crew move around the yacht — separately from guests — shapes the whole layout.

• Crew cabins, crew mess and a dedicated crew stair
• Galley location and service routes to the dining areas
• Separate guest and crew circulation
• Captain's cabin, often near the bridge
• Crew numbers set by safe manning, use and service level
• Watch-keeping and rest hours set by flag and use

Class, flag and commercial code are three different things, and each affects how a yacht can be used and sold.

• Class society: technical standard and periodic surveys
• Flag state: registration, manning and safety rules
• Commercial code: needed for charter in many jurisdictions
• Private or commercial registration affects tax, crew and use
• Class survey due dates affect near-term cost
• VAT and ownership status must be documented, never assumed

• Independent pre-purchase survey, out of the water
• Engine and generator survey, oil analysis, hours and service history
• Class status and upcoming survey dates
• Refit history: what was done, by whom and when
• Paint and coatings, teak decks
• Stabilisers, thrusters and hydraulics
• AV/IT, network and cybersecurity
• Tonnage, flag, VAT and ownership documents
• Sea trial run by the yacht's captain with your surveyor present

Engine and machinery testing should be carried out only by qualified surveyors and the yacht's crew.

Many yachts at this size change hands privately, before or without a public listing. With a clear brief, we approach brokers and owners' representatives discreetly. We cannot promise off-market inventory; every opportunity is confirmed with its owner first.

We position your yacht against true comparables — same size band, build type, generation and volume — and present it discreetly to qualified buyers. Sell your yacht →
