Most ships are using conventional hull form, i.e. a mono hull with holds for cargo and decks and superstructure for passengers accommodation.
With the same displacement and power consumption, catamaran and SWATH can move faster on the surface of the water. Therefore, they are also called high speed marine vehicle. SWATH ships are used to transport people in short distance. Faster speed means higher power. Improvements in photovoltaic technology have to be done in order to increase its efficiency so that it can easily be applied into many other applications both at sea and on land.
Unfortunately, the cost of construction for these ships is still higher than the conventional mono hull ships.
