Inflatable boats with water release valve

Water release valve

— a special valve that allows you to drain water from the cockpit of the boat through the bottom — and many models allow you to do this right on the go (after all, the buoyancy of the boat does not depend on the integrity of the bottom, but on the fullness of the cylinders). Removing liquid in this way is much more convenient than bailing it out or even turning the whole boat over.
