One of the other signs of spring is spring buoy placement.The Coasties are busy with the spring job of marking navigation routes, channels and hazards.
The 140-foot Bay-class Cutters are state of the art icebreakers used primarily for domestic ice breaking duties. They are named after American Bays and are stationed mainly in Northeast U.S. and Great Lakes. WTGBs use a low-pressure-air hull lubrication or bubbler system that forces air and water between the hull and ice. This system improves icebreaking capabilities by reducing resistance against the hull, reducing horsepower requirements.
The Cutter found in Sturgeon Bay is WTGB 103 - the Mobile Bay.
