By using Humphree's trim and stabilization system, you will reduce resistance, fuel consumption and environmental impact. It also means that the best possible performance and stability is achieved.
Humphree USA reports that it has won numerous orders this year for its automatic stabilization technology in the North American pilot boat segment, with nine new boats either delivered or under construction for eight different pilot associations.
This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.
