Yacht Purchase Due-Diligence Guide

A detailed guide to surveys, sea trials, documentation, operating costs, insurance, crew, and closing checks before buying a yacht.

Define the operating profile before choosing the vessel

The right yacht depends on how it will be used: day trips, coastal cruising, extended passages, charter, entertaining, family travel, or seasonal residence.

Range, draft, speed, stabilization, crew requirements, tender capacity, storage, and marina access should match the intended use rather than an aspirational brochure.

Commission an independent survey

A purchase survey should evaluate hull, machinery, electrical systems, safety equipment, navigation, generators, plumbing, corrosion, moisture, and compliance issues.

Use a surveyor who is independent of the broker, seller, and yard. Significant findings should be converted into repair estimates and negotiation decisions.

Conduct a meaningful sea trial

The sea trial should test engines under load, steering, vibration, noise, stabilization, electronics, charging systems, generators, anchoring equipment, and onboard systems.

A brief demonstration is not the same as a structured sea trial. Document performance and unresolved issues.

Verify title and documentation

Confirm ownership, liens, registration, tax status, import history, maintenance records, class records where relevant, and compliance with applicable rules.

Complex ownership structures or multiple jurisdictions may require specialized legal and tax advice.

Model the operating budget

Include crew, fuel, dockage, insurance, maintenance, haul-outs, paint, electronics, tenders, safety equipment, management, travel, and major refits.

Budgeting only a percentage of purchase price can hide the effect of age, complexity, usage, and local costs.

Plan the first year before closing

Identify the home marina, insurance requirements, crew plan, immediate repairs, registration, management, and expected itinerary before ownership begins.

A well-planned first year reduces the chance that the yacht becomes unusable while unexpected work is completed.
