The following ships have designation:&nbsp;&nbsp;<br />
<b>WTGB&nbsp;&nbsp;-&nbsp;&nbsp;140-FOOT ICEBREAKING TUG</b><br />
<br/><br/><br />
Number in service Coast Guard-wide: 9<br/><br />
Length: 140 feet<br/><br />
Beam: 37.5 feet<br/><br />
Displacement: 662 tons<br/><br />
Power plant: Two diesel engines<br/><br />
Commissioned: 1979-1988<br/><br/> <br />
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. <br />
<br />
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 <br />
