Self-Propelling Vessel Design & Construction
Ⅰ. Introduction
The process of working through details of a problem to reach a solution is called problem solving. Abstract and creative thinking are preferred in working out the best solution. There are about 5 stages to solve a problem: evaluating the problem, managing the problem, decision -making, resolving the problem, examining the results.
The subject for current project is to design a self-propelling
