Since 1978 Lyman-Morse has built more than 110 vessels, ranging from aluminum workboats to high-end composite racing yachts and luxury power yachts. “Their experience with so many different building materials opens up a world of new possibilities for our vessels,” says Baltic Workboats’ CEO Margus Vanaselja.
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.
