FIELD: shipbuilding; building of multi-hulled ships. ^ SUBSTANCE: proposed catamaran has two hulls in form of oblong cylinders with cone-shaped fore and aft extremities, decks, propellers and steering gear. Hulls are interconnected by means of horizontal transversal rods in above-water portion and longitudinal keel girder which is connected with hulls by means of inclined rods in under-water portion of hulls. Said connection members form truss together with hulls in form of triangular prism; adjoining to bases of this prism are pointed sections in form of triangular pyramids whose vertices lie on ends of keel girder. Angle at which faces of prism intersect is equal to 40-70 deg. Ratio of width between axes of hulls to their length is 0.5-1.5 and ratio of length of hulls to length of keel girder is equal to 0.3-0.9. ^ EFFECT: improved service characteristics of ship and improved sea-worthiness of ship. ^ 10 cl, 5 dwg |
