USCGC Katmai Bay (WTGB-101) is a United States Coast Guard Cutter and icebreaking tug.

DesignEdit

Katmai Bay, namesake of an area of saltwater shoreline in the Katmai National Park and Preserve of Alaska, is the lead ship of a class of icebreaking tugboats designed to have greater multi-mission capabilities than the 110' Calumet-class Harbor Tug (WYTM). The most significant differences include greater horsepower, greater speed, longer range, increased ice-breaking capability, hull lubrication system, greater degree of automation, and better habitability.[1]

Trials were conducted in Whitefish Bay, Lake Superior, Michigan which determined that the ship has a tactical diameter of approximately three ship lengths when using 30 degrees rudder and that the ship could stop in 40 seconds with a reach of four ship lengths from an approach speed of 12.8 knots (23.7 km/h; 14.7 mph) when ordering full astern power. The ship can obtain a speed of 14.7 knots (27.2 km/h; 16.9 mph).[1]
