Aeroyacht Type Denhaut I: This handsome biplane flyingboat was entered at Monaco in 1913, painted with the number 9. The upper wing had substantial overhang; outside the center-section, it was separated from the small triangular sesquiplane lower wing by struts at the leading edge only, the rest by wires for flexibility in wing-warping. The horizontal tail was fixed on top of the cut-off fin and rudder.

   Aeroyacht Type Denhaut II: The wing arrangement was similar to that of Type I (perhaps the same machine, modified?), but with cut-outs in the small lower wings. The tail was new, with a distinctive long trailing point to the rudder, and the tip floats were of a different shape.

   Aeroyacht Type Denhaut III: Clearly a development of Types I and II, this machine featured an even longer trailing rudder tip, longer lower wings, and conventional double-strut bracing - though still with wing-warping. It was powered with a 10-cylinder Anzani and competed in the Paris-Deauville meet in 1913, carrying the number 10.

   Type Monaco: This interesting flyingboat also entered the meet at Monaco in 1913. It featured a short hull with the 160 hp Gnome buried inside the hull, driving the 4-bladed pusher propeller through chains; 2 big cylindrical tanks were mounted above the hull under the wing; a streamlined cowl with an oval window on each side was set ahead of the 2 pilots. The aft fuselage, like the military pusher monoplane of the same year, comprised a triangular girder whose top longeron was fitted to the propeller hub and a bearing.
