Six-component measurements of a model of a wing-in-ground effect craft (WIG) “Marine Slider: μ sky” were conducted in a low speed wind tunnel using a running belt as the ground plane. The “μ sky-1” was an experimental marine craft with a simple ram wing. Its wing section was a high cambered thin section to improve its performance in the ground effect. The wing of the test model was a square wing of the aspect ratio 0.625 with tip plates extending downward from both tips. Results obtained show that the ground effect is remarkable for this wing. The drag was reduced not enough. The reason was that there was a strong shear flow in a narrow clearance between the hull bottom and the ground surface. The shear flow increased the drag.
