KATMAI BAY (WTGB-101) SPEED, TACTICAL, AND MANEUVERING TRIALS
This report contains the results of tactical and maneuvering trials and speed versus shaft rpm trials conducted on United States Coast Guard Cutter KATMAI BAY (WTGB-101). KATMAI BAY is the lead ship of new class of icebreaking tugboats. The trials were conducted in Whitefish Bay, Lake Superior, Michigan. Tactical data determined that the ship has a tactical diameter of approximately three ship lengths when using 30 degrees rudder. Maneuvering data indicated that the ship could stop in 40 seconds with a reach of four ship lengths from an approach speed of 12.8 knots when ordering full astern power. Ship's speed versus propeller shaft rpm trials indicate that the ship can obtain a speed of 14.7 knots at an average rpm of 303.7. (Author)
