DIRECTIONAL STABILITY OF THE WYTM ICE BREAKING TUGBOAT AS REPRESENTED BY MODEL 5336
The results of spiral maneuvers conducted with Model 5336, representing a preliminary design of the WYTM Ice Breaking Tugboat, indicate that the ship, when appended with a 61 or 73 square foot rudder, will be directionally stable at ahead speeds of 5 knots and above. The results further indicate that when appended with a 49 square foot rudder, the ship will only be marginally stable at a ship speed of 5 knots. Regardless of which of the three rudders is used, the neutral rudder angle will be between 0.6 and 1.0 degrees right.
