Two bow and two stern thrusters provide port manoeuvrability, and two pairs of stabilizer fins reduce rolling. A special silicone-based paint, instead of biocides used by much of the industry, keeps barnacles off of the hull. This increases her efficiency by reducing drag while also protecting the ocean from biocides that may leak. The paint is credited with lowering the water drag enough to save 1,200 tonnes of fuel per year. The ship has a bulbous bow, a standard feature for cargo ships.
