Ship-Calculations Ver 0.98
These tutorials could be used in a beginner's course on Ship Stability, developed at <a href="http://wavelinklms.edu.sg">Wavelink Maritime Institute, Singapore</a> . The material is based on the well-known text book - Reeds Vol 13: Ship Stability, Powering and Resistance (Reed's Marine Engineering and Technology), 2014 [Christopher Patterson, Jonathan Ridley]. It is hoped that these calculation-examples using GeoGebra will reduce the calculation load for the students and help them explore various what-if situations easily.
