Coast Guard Station Portage boatcrews conduct training exercises aboard their 47-foot Motor Life Boat and 25-foot Response Boat-Small near Dollar Bay, Mich., Aug. 29, 2012. The 47-foot MLB is designed to perform heavy weather rescues with up to 50-knot winds and 20-foot breaking seas, and the 25-foot RB-S is a faster, more nimble response asset, but cannot operate safely in heavy weather conditions.
