Designing in practice can be carried out in many ways. At Werner Yacht Design we have two main rules that we follow: Firstly we consider as many aspects of boat building as possible in the preliminary design, detect all possible challenges that might occur in the design, and address these issues straight away. Secondly, as a basic practice we always divide the process of designing into four stages, Design, Lines plans & Calculations, Construction, Interior / Exterior. Every single stage is always completely finished before the next one is started. This means that the parameters for every stage are set. Consequently one only has to look forward.
Working this way will not necessarily result in a cheap design, but it does guarantee a very high standard of precision, and a smooth and cost efficient building process, that leaves you with little to worry about.
