The paper presents the review of design experience and applied research of catamaran craft, up to 30m in length, of total over 30 catamaran designs, developed by 'Albatross Marine Design' and launched during recent years. Architecture of catamarans is discussed; typical catamaran hull shapes are reviewed and their suitability for different applications and desired speeds are studied. Recommendations are given for hull shape particulars selection. Performance issues are studied using available theoretical methods and sea-trials data of number catamarans. Components of resistance of catamarans and methods of their prediction are reviewed. Comparison of methods is presented and samples of their applications for hull shape selection are shown. Seakeeping performance is discussed in terms of vertical accelerations. Results of full-scale measurements of vertical accelerations on number of craft are presented. Controllability discussion is based on turning track measurements for power catamarans of different configurations at different speeds. Structural design issues are reviewed with special interest in composite craft and their improvements. Perspective applications of catamaran concept for different types of craft are indicated, including workboats and wind farming. Presented are samples of catamaran designs for special, small commercial and pleasure catamarans. © 2014 The Royal Institution of Naval Architects. Source
