Shipbuilder Metal Shark is building a welded aluminum 55’ x 17’ pilot boat for the Pascagoula Bar Pilots Association in Mississippi.
Designed in-house, the new 55 Defiant Pilot being built for Pascagoula Pilots represents the latest evolution in Metal Shark’s pilot boat lineup.

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.
