| Summary: | Yachts tend to roll uncomfortably whilst at anchor, causing discomfort to the crew and passengers, generating stresses on equipment, and making operations such as embarking and disembarking hazardous activities. A research program is under way to better understand the design factors and environmental influences leading to the rolling problem, with a view to providing effective solutions. A numerical model has been written which incorporates the results of tests on stylised keels under forced oscillation and the results compared with full scale trials on a yacht. The results holdinteresting implications for the design of those yachts for which safety and comfort when not under way are important criteria. |
