Abstract : The recent availability of low cost, relatively powerful computers has had a major impact on experimental and analytic hydrodynamics. Application of these devices to control, data acquisition, and data analysis for ship maneuvering tests can result in improved cost efficiency, data quality, and interpretation of results. During the past year Offshore Technology has developed a low cost microcomputer-controlled planar motions mechanism, improved techniques for analysis of resulting data, and a simulation model capable of running on a small personal computer. Hardware design, software, operating features, and typical data resulting from these techniques are discussed. These are compared to typically used hardware and techniques and further design improvements are recommended. In addition, designs for microprocessor-based model control system and a digital model tracking system, which are currently under development are discussed.
