Self-locking raft with tail sliding sections

A design of the self-locking raft with sliding tail sections is presented. The featured purpose of the proposed raft is to create with the help of its sliding sections the necessary supporting force when turning along curvilinear parts of the river and to prevent dislocation of its tail part toward the concave bank of the river. When turning to the left, slowing down is accomplished by the rear left section, and on turning to the right - by rear right section.
