Balsa raft

A balsa raft is a lightweight, buoyant vessel made primarily from balsa wood, known for its high strength-to-weight ratio. Balsa wood's low density allows the raft to float easily on water. These rafts are often constructed for educational, recreational, or survival purposes, utilizing simple design principles such as stacking or lashed balsa logs. Their minimal weight makes them easy to transport and assemble, while their buoyancy provides reliable floating capacity. Overall, a balsa raft exemplifies efficient use of lightweight materials to create a functional floating platform.
