§ Fitting the Fleet Inside
The Salon Nautique international de Paris held its first edition in 1906, making it one of the oldest specialist consumer fairs in France. For much of its early life the show occupied the Grand Palais, where the nave's 45-metre-high iron-and-glass vault gave organisers the ceiling height they needed for stepped displays of sailing craft and motorboats. The floor, however, was never built for the loads that a collection of fibreglass hulls on steel cradles imposes, and the tension between the building's prestige and its structural limits was a recurring constraint.
The show moved to the Porte de Versailles in the 1960s, where the purpose-built exhibition halls offered floor loadings the Grand Palais could not. That shift reframed the engineering problem. The question was no longer whether the floor would bear the weight but how to display a 12-metre motor cruiser — or, in later decades, a sailing yacht of comparable beam — in a way that let visitors walk beneath the keel, step aboard via gangway, and read the hull lines at eye level. The answer developed at Porte de Versailles relies on a combination of purpose-built steel cradles, hydraulic lifting rigs brought in during the build-up, and a grid of reinforced floor sections rated to absorb concentrated point loads from keel blocks.
Water itself is present at the show in a modest but structurally significant form: a shallow in-hall basin, installed in one of the main halls, allows a selection of inflatable and rigid-inflatable vessels to be moored afloat rather than propped on stands. Filling even a shallow basin to a usable depth across several hundred square metres places a load on the hall floor that must be calculated against the slab's rated capacity — the water alone, at roughly one tonne per cubic metre, constitutes the heaviest single element in the hall during show week.

- 1960sshow transferred to Porte de Versailles, purpose-built halls with higher floor-load ratings

The Salon Nautique today occupies the Porte de Versailles site across multiple halls, drawing exhibitors from French builders including Bénéteau and Jeanneau alongside international marque holders. The Fédération des Industries Nautiques, the trade body that has co-organised the event since the postwar period, publishes attendance and exhibitor data from each edition, providing the most reliable continuous record of the show's scale.
