Review on Advance Seaplane Conceptual Design Adapting Trimaran Boat Hull Concept

The decline in the research of seaplanes started after 1950, when the focus shifted towards improving the infrastructure of land-based aircrafts. Existing designs with minor improvements are being used since then. The goal is to critically discuss the parameters one by one based on which a specific design configuration of a seaplane is evaluated in this paper. Trimaran based configuration is based on a blend of float plane and flying boat. It has lower aerodynamic drag once airborne. The hydrostatic stability is achieved by the restoring moment generated by the interaction between c
g
and m
c
height. They have superior stability achieved by the restoring moment generated by the interaction between center of gravity and meta center height.
