Abstract: A water walking apparatus including a pair of elongated pontoons by which a user is able to propel himself through the water with a walking motion. The pontoons have longitudinally extending tunnels with flippers therein and have ballast tanks with buoyancy adjusting valves. The pontoons are formed with pitch dampeners thereon for improved stability and may also be provided with inertia reducers and improved propelling fins or flippers to increase the speed and distance travelled with the expenditure of a given amount of energy.
