Cradles are always needed for supporting the yachts during their construction and transportation. Local concentrative forces loaded by the non-uniformly distributed weights of yacht itself are only applied on the certain contact area between hull and cradle brackets. The deformed FRP hull, cracked gel coat, the distorted furnished interior and joinery work all cost the builder a lot to repair the imperfections. Moreover, even in the worst condition, the safety issue occurs owing to the structure failing which might not be solved by money only. This paper aims to establish the deformed measurement system for the yachts. Combined with the information of existing cradle, such as dimension, material and the measured data, finite element model of a target boat including whole boat structures, for example, hull, bulkheads and stiffeners, etc, can be established. By using commercial FEA software ABAQUS, the response of the structure supported by cradles can be obtained, and compared with the measured data to validate. It would help the optimization of the design of hull and cradle and reduce the problems caused by deformation.
