This research has been performed with the goal to set up a model for the comparison of the environmental impact caused by the production of yachts. This model is created in such a way that it can be implemented in the YETI, Yacht Environmental Transparency Index, which is currently under development. The model that is created is based on a Life Cycle Assessment methodology named Fast Track LCA. This methodology consists of five steps which are further standardized to meet the requirements of the YETI. Choices are made for the functional unit, system boundaries, the quantification of materials, the assessment method, environmental database and LCA software. With a case study, the created model is validated as the results have realistic values. Some other design choices are applied on the case study to check the sensitivity of the model. The sensitivity was enough to show the effect of a different hull material and the use of batteries for the hotel load and peak shaving. It is concluded that the model can be used for the comparison of the environmental impact from production of different yachts. However, it should be noted that due to design choices for the model based on the requirement for comparison, the outcome itself is an underestimation of the environmental impact from yacht production.
