The Study of Shape Flat Hull Ship Toward Resistance

Flat hull ships are increasingly being used in Indonesia for fishing boats, passenger ships and tourist boats. However, this sort of ship has a shortcoming in terms of the enormous resistance compared to streamlined hull vessels, therefore it is necessary to study the hull design of the flat hull ship. In addition, the purpose of this research was to study the effect of the shape and arrangement of the flat plates that form the hull of the ship on the resistance. The research method was the comparator ship method in which the design of the ship models with a flat plate hull was compared to the resistance experienced with a ship with a streamlined hull form (comparator ship). Hence, to reveal the resistance experienced by each ship model, this research used the Maxsurf Resistance Software. The results of the study found that the more similar the hull plate arrangement of a flat hull ship with a comparator ship, the closer the resistance being experienced. The unevenness of the flat hull ship causes energy losses that make the ship have high resistance.
