'''USCGC ''Katmai Bay'' (WTGB-101)''' is a United States Coast Guard Cutter, and the lead ship of the Bay-class of icebreaking tugboats. At {{convert|140|ft|abbr=on}}, she is designed to have greater multi-mission capabilities than the 110' ''Calumet''-class Harbor Tug (WYTM). She is homeported in Sault Ste Marie, Michigan, operating in support of the much larger {{USCGC|Mackinaw|WLBB-30}}.

==Design== ''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.<ref name=Trials/>

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 {{convert|12.8|kn}} when ordering full astern power. The ship can obtain a speed of {{convert|14.7|kn}}.<ref name=Trials> {{cite web |first1=Robert R. |last1=Hunt |first2=Lowry L. |last2=Hundley |title=Katmai Bay (WTGB-101) Speed, Tactical, and Maneuvering Trials |website=Defence Technical Information Center |year=1979 |url=https://apps.dtic.mil/sti/citations/ADA077587 |access-date=10 March 2009 }}</ref> thumb|600px|right|''Katmai Bay'' breaking ice
