A ship is supported by her buoyancy, advanced by her propeller thrust and turned by her rudder force. These forces arephysically caused by hydrostatic and hydrodynamic phenomenons around a ship. Students of the department of maritimetechnology should have a proper understanding of the above hydrostatic and hydrodynamic phenomenons around a ship.But it is not easy to understand the above complicated phenomenons for students.In order to make the above hydrostatic and hydrodynamic phenomenons more easily understandable, following twokinds of learning aid materials were developed.1. Hands-on training tool for Ship HydrostaticsDesktop hands-on training on heels and trims of a ship.2. Flow visualization materials for Ship HydrodynamicsFlow velocity and pressure distributions, which were analyzed by CFD, around a rudder and a propeller blade.Lessons using two learning aid materials are tried and also questionnaire surveys on their educational effects were carriedout. The results of the questionnaire showed good teaching effectiveness of the developed learning aid materials onhydrostatic and hydrodynamic phenomenons around a ship.
