Roll Motion of Yachts at Zero Froude Number
MetadataShow full item record
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.
