Stabilisaattolauttoja, known in English as stabilizing rafts or pontoons, are buoyant structures designed to provide stability and buoyancy to vessels, particularly in offshore or demanding marine environments. They are typically attached to the hull of a ship or platform and can be either fixed or retractable. Their primary function is to increase the vessel's metacentric height, thereby reducing roll and pitch motions.

These structures are often employed on specialized vessels such as offshore construction platforms, heavy-lift vessels, and some types of research or survey ships. In some cases, stabilizing rafts are also integrated into the design of ferries or passenger vessels to enhance passenger comfort, especially in rough seas. The design and size of stabilizing rafts vary depending on the specific application, considering factors like the vessel's displacement, expected sea conditions, and operational requirements.

The principle behind their operation is simple physics. By increasing the vessel's beam or by strategically placing buoyant volume, the center of buoyancy is raised relative to the center of gravity. This increased separation creates a larger righting lever, which counteracts the heeling moment caused by waves, thus reducing the vessel's tendency to heel or capsize. Materials used in their construction typically include steel, aluminum, or composite materials, chosen for their strength, corrosion resistance, and buoyancy. Their deployment can significantly improve operational safety and efficiency in challenging maritime conditions.
