Kajian eksperimen: pengaruh water rudder pada olah-gerak kapal bersayap

The casually reports based on many institute in the world indicated that one third of casualties of collision, ramming, and grounding of tank vessel was due to poor controllability of the ship. Therefore the manoeuvring qualities of ship are very important to justify at the design stage. This paper describes the effects of water rudder on the manoeuvrability characteristics of WISE (Wing In Surface Effect) craft model design. The manoeuvring tests comprise tuming circle tests, directional course stabilly tests. The free running model test was carried-out in wave basin with a certain ship speed and loading conditions, Finally the test resulls are discussed in detail to understand these effects on the ship manoeuvrability.
