Once inflated the sealed inner bladder retains its air so a continuously operating air blower is not required.

On the water the arch can mark a start finish checkpoint or course section for open water swimming triathlons rowing SUP and other water sports. Floating inflatable arches are used where athletes need a large visible course marker away from the shore. On land the same type of sealed air structure can serve running and cycling races festivals promotional areas and entrances. For water installation the arch must be secured with suitable mooring or anchoring lines to reliable fixing points.

Dimensions: width 5 m height 3 m depth across the supports 2 m. The structure consists of a sealed inner bladder and an outer cover that forms the arch and support sections. The inner bladder can be made from polyurethane or another suitable airtight material depending on the chosen construction. Similar professional airtight arches use a two layer system with a sealed chamber inside a separate outer shell and operate without continuous airflow.
