ABSTRACT
Following the established 3-stage R & D program of super-high-speed ships, a study on the conceptual
design of a large-size super-high-speed foil catamaran containership has been performed as the 3rd(the
final) stage work utilizing the accumulated experience and technology. In this paper, some main
features in the conceptual design shall be briefly discussed together with the present technical problems
in realizing actual ships.

1 INTRODUCTION
Hyundai Maritime Research Institute(HMR1) prepared a Three-Stage R and D Program for super-high-
speed ships in 1990 and has actively camed out the research works following the established plan. As
the largest single shipyard in the world, however, the ultimate goal of the research is in the development
of large-size super-high-speed ships. In this respect, the first and the second stage studies for the
development of small and medium size super-high-sped ships are regarded as the intermediate steps to
achieve the above goal. Therefore, the decisions on ship type and main characteristics have been made
considering the ultimate goal.

In order to increase ship speed significantly, it is necessary to prevent the rapid increase of resistance.
This purpose could be achieved in different ways. One way is to utilize the dynamic or static lift effects.
For dynamic or static effect ships, however, it is extremely difficult to increase the ship size beyond a
certain limit, which is regarded as the fatal disadvantage of these types of ship.

On the other hand, the hull form of displacement-type catamaran ships could be made very fine so as to
achieve the goal of high speed by preventing rapid increase of wave resistance. Among many practical
advantages of catamaran ships, the most noticeable merit is in the fact that ship size could be easily
increased without any limitations and without sacrificing any other characteristics.
