For davits it is crucial to be able to launch lifeboats even under extreme conditions like 20° list and 10° tilt. The engineer carries the responsibility to ensure, that constructed davits satisfy this requirement. In this paper a parameterized simulation model for simulating the movement of the davit over time is presented. The parameterization allows adapting, e.g. the amount of stored power, the weight of the life boat or several geometric properties. The simulation model is coupled with a virtual reality system allowing the disembarking procedure to be visualized before even a prototype is built. The paper demonstrates how virtual prototyping can be used to support the design process even for small and medium enterprises.
