A greater concern is how well a ship cuts through waves. The ability of a ship to cut through waves can greatly affect its fuel efficiency and even its safety in a storm. Most ships use a sharp bow to cut through waves and help prevent waves from slamming the bow of the ship. Icebreakers with the round; sled-like bow used to ride up on the ice; tend to slam into waves and can be a risk in high seas. Recent advances in ship propulsion have produced new experimental icebreakers. Electrically driven propellers are mounted to steerable pods under the ship. These Azimuthing Podded Propulsors, or ''Azi-pods'', improve fuel efficiency, ship steering, ship docking, and removes the need for rudders. Azipods also allow a ship to travel backwards as easily as it travels forward. The double acting icebreaker is unique beacuse its stern is shaped like an icebreaker's bow. Normally travelling forward, a double acting icebreaker uses a conventional ship bow for a more comfortable ride. When ice is encountered, the ship turns around and drives backward through the ice. The [[MT Mastera]] and [[MT Tempera]] are two vessels using this new technology.
