Coast Guard Cutter Katmai Bay departed the Coast Guard Yard in Curtis Bay, Maryland, Sept. 29, 2018, following completion of service life extension project activities as part of the In-Service Vessel Sustainment (ISVS) Program. Katmai Bay is the sixth of nine 140-foot icebreaking tugs to undergo work through ISVS. The program is extending each cutter’s service life by 15 years and is completing upgrades to propulsion and electrical systems, replacement of the boat-launching davit and habitability improvements. The tugs entered service in the 1970s. Katmai Bay will return to Sault Ste. Marie, Michigan.
