Sailing Island was developed for Nodeulseom Island, in the Han River, as part of a public art competition organised by the Seoul Metropolitan Government. The project proposes a field of vertical masts and rotating sails that respond to the changing direction of the wind, turning an invisible environmental condition into a visible and inhabitable sequence.

The installation works through two simultaneous readings of the river. When the wind arrives from one direction, the sails align to reveal a curving path that recalls the former, softer edge of the Han River. When the wind changes, another alignment appears, closer to the straightened and engineered river that defines Seoul today. The work therefore acts less as a fixed object than as a changing drawing made by air, fabric and time.

Its geometry was generated through a parametric process that positioned and dimensioned each element while avoiding collisions between moving parts. This digital system was later tested through physical prototypes, simulations and construction details, translating an abstract sequence of forces into a buildable public installation.

During calm moments, the field becomes open to direct interaction. Visitors can move between the masts, rotate elements and produce temporary compositions of their own before the wind reorganises the installation again. The project remains suspended between landscape, infrastructure and collective play.
