About Guillaume Verdier, Naval Architect

After graduating in naval architecture in 1995, Guillaume Verdier joined the research programme at the University of Copenhagen. In 1997, the Groupe Finot offered him a position in their team.

He then specialized in the open sea racing field, by taking part in the design of boats striving for performance: 40, 50 & 60 footers on his chart table.

In 2001, Guillaume Verdier created his own naval architecture company. Commissions soon flowed in. With his team, he worked on his own projects and on partnerships. With Yves Parlier, he took part in the design of the Hydraplaneur “Mediatis Region Aquitaine”. He also rehabilitated the PRB 60 foot monohull in collaboration with Groupe Finot. Finally, he partnered with the VPLP office to design Safran and Bel’s 60 foot boats.

In 2004, Areva Challenge contacted him to take part in the design and conception of the America’s Cup Class boat for the French team. The boat raced in the 32nd America’s Cup in Valencia in 2007 (Spain).

With his twenty years of experience, Guillaume Verdier is at the origins of many successful projects.


    The expertise of the Guillaume Verdier architectural office revolves around three fields of major competences.

    • Conceiving structures
    • Studying hydrodynamic and aerodynamic shapes
    • Predicting performance

    Three areas of study that are essential for the design of innovative boats striving for performance.

    Guillaume Verdier’s point of view on the naval architecture profession

    “The office’s job is fascinating because it involves taking into consideration numerous inseparable parameters.

    We consider that our role does not only consist in drawing the lines of hulls. Quite the opposite, for a boat’s design to be harmonious, we work on hydrodynamic and aerodynamic shapes at the same time as on the structural calculations and performance predictions.

    Concretely, a thick keel provides better rigidity and limits vibrations, but it will generate more hydrodynamic drag. The structural calculations must be linked to the hydrodynamic shape for the result to be coherent, homogenous and consistent with the objectives aimed for.

    Our job consists in synthesizing all of these fields. We work with different computer programmes and we develop many tests, such as tank tests for hydrodynamics, or wind tunnel tests for the aerodynamics.

    The multiple parameters provide a broad spectrum of possibilities. We can make specific choices according to the sailors or shipyards with whom we work. Adapting to our clients’ needs adds a fulfilling human dimension to our activity, which is essentially very scientific.

    Lastly, working on race projects that are constantly evolving requires us to be at the cutting edge of new technologies. We ensure permanent monitoring and regularly undertake research.

    Constant re-assessment and open-mindedness are absolutely crucial to the success of our projects.

  • Resources

    • Partnership with Microsoft for access to resources and a calculations cluster
    • Routing architecture type software developed thanks to the Microsoft partnership and with Benjamin Muyl for better targeting of hull choices.
    • Partnership with Siemens and Unigraphics Solutions for finite element analysis, computational fluid dynamics and CAO software.
    • CFD software (Volume of Fluide) developed originally by the University of Nantes, then by Fine Marine to simulate runoff specific to the water-air interface going up to the separation of free surface (e.g.: spray simulation)
    • The Guillaume Verdier architecture office also uses for most of its designs the following programmes: SIEMENS – UNIGRAPHICS SOLUTIONS – NASTRAN, WOLFSON UNIT VPP programmes (Velocity Prediction program), a CFD programme (Computational fluid dynamics), and its own calculations software, MADSYS (© Guillaume Verdier).

After training as a naval architect at Southampton Institute, Guillaume Verdier designed his first racing boats within the Groupe Finot. In 2001, he set up his own shop and took part in the creation of racing boats within his own design office.
