The foreship of Tempera is designed for open water performance with a bulbous bow to maximize the hydrodynamic efficiency.

It would seem reasonable to think that the regular spacing and size uniformity of fish in schools would result in hydrodynamic efficiencies.

A hydrodynamic efficiency of 40% has been achieved during the field tests.

It is also likely that fish benefit from shoal membership through increased hydrodynamic efficiency.

Its body was streamlined for greater hydrodynamic efficiency, which along with its finned tail made it a more efficient swimmer than modern crocodilian species.

Therefore, natural selection seems to lead to the evolution of an effective crocodilian snout by creating a mechanical compromise between bite force and hydrodynamic efficiency.

Unfortunately for the designers, the widened beam meant that an even longer hull was needed to maintain hydrodynamic efficiency.

This stiffness would have improved hydrodynamic efficiency by improving the flow of water across the body.

While successful, the bow bulge required to contain the operating mechanism reduced hydrodynamic efficiency and lowered her overall speed.

High power density and the hydrodynamic efficiency of a longer hull form allow high speeds to be sustained.
