PURPOSE: An apparatus for decreasing drag of a side thruster hole of a ship is provided to prevent the loss of power by minimizing the generation of drag in a thruster hole due to seawater. CONSTITUTION: An apparatus for decreasing drag of a side thruster hole of a ship comprises a seawater blocking part(30). The seawater blocking part blocks inflow of seawater into a thruster hole in the sailing of a ship, and is arranged in the leading end of an entrance of an thruster hole(11) based on a progressive direction of a ship. The rear end of the seawater blocking part is outwardly bent from the thruster hole. |
