Abstract
A dualistic stern-appendant device comprises, in integrated form, at least two gate-supportive bodies and at least one flap-hydrodynamic body. The device is characterized by an alternating arrangement of bodies (totaling an odd number of at least three bodies) whereby no two consecutive gate-supportive bodies are next to each other and no two consecutive flap-hydrodynamic bodies are next to each other. Each gate-supportive body has an upper surface which is a gate-supportive surface, all of the gate-support surfaces together representing a cumulative gate-supportive surface. Each flap-hydrodynamic body has a lower surface which is a flap-hydrodynamic surface, all of the flap-hydrodynamic surfaces together representing a cumulative flap-hydrodynamic surface. The geometric plane defined by the cumulative gate-support surface is not encroached upon by any flap-hydrodynamic body. The ship's bottom hull surface and the cumulative flap-hydrodynamic surface together represent an extended, continuous bottom hull surface having associated hydrodynamic benefits (e.g., improved ship's powering).
