Our fields of expertise
Acquiring, insuring, or constructing a large sailing yacht involves significant technical, financial, and legal considerations. Our surveys aim to secure these decisions through thorough, independent, and documented analyses.
We follow a structured methodology based on maritime standards (ISO) and best practices, ensuring rigor, traceability, and objectivity in all technical assessments.
Pre-Purchase Survey
A comprehensive assessment of the yacht’s technical condition in the context of a purchase or sale.
Construction Supervision
From full project oversight to targeted inspections at delivery, we provide owners with an independent and rigorous perspective, ensuring compliance, quality, and peace of mind.
Damage Survey

Performed exclusively on behalf of insurance companies, covering the entire Spanish Mediterranean coast and the Balearic Islands.
Osmotic Survey
Conducted for owners and insurance companies to evaluate moisture levels in the composite materials of the hull.
Pre-Insurance Survey
Intended for owners wishing to reassess their insurance policy following a major refit or significant modifications to their yacht.
Methodology & Independence
All surveys are performed using a structured, consistent, and fully documented methodology.
Each assignment is traceable, ensuring objective analyses and reliable conclusions. We operate independently, without any links to shipyards, brokers, or service providers, and maintain strict confidentiality of all cases.
