A Concept of the Triple-Hull Frigate

Ships with outriggers, such as multihull vessels, are defined and their advantages and disadvantages described. The general feasibility of a hull with a small waterplane area is considered as a method for development of an outriggered frigate design. The main dimensions, general arrangement, and hull structure of this design are offered along with calculations of initial transverse stability, longitudinal bending moment in waves, wetted area, residual resistance coefficient of the single hull, as well as the hydrodynamic interaction of the main hull with the outriggers.
