Technological factors for development of advanced sail-assisted ships are studied. Aerodynamic performance of hybrid-sails consisting of a slat, a hard sail and a soft sail is investigated by wind tunnel test. Interaction effect among plural hybrid-sails and that between hybrid-sails and ship hull are also investigated. Underwater fin arrangement and its hydrodynamic characteristics are measured in a towing tank, and estimation formulae of underwater fin effect are proposed. In order to investigate into advantage of wearing underwater fin quantitatively, sailing performance in steady condition is calculated. A practical hybrid-sail which utilizes deck crane as its boom is designed and its aerodynamic characteristics are measured by wind tunnel test. Weather routing system for an advanced sail-assisted ship is developed, and advantages of the hybrid-sail and the weather routing system are estimated based upon calculation applied to a bulk carrier on North Pacific Ocean route.
