After seeing the images of the American Coast Guard and the Italian Coast Guard practicing in the sea with very high waves, today we bring you on board with this video of the US Coast Guard to understand or at least imagine what it means.
An extreme motor boat for extreme conditions
The motor boat in the photos is the 47 foot MLB of the United States Coast Guard, successor to the historic 44′ MLB. This is the standard lookout provided in the U.S., an extreme boat designed to act in extreme conditions such as those that may occur overseas.
What can the 47 foot MLB withstand?
winds with the force of hurricanes, up to 60 knots
breakers up to 6 meters
with very strong impacts
to the overturning, in fact in case of “cupsize” this boat returns straight in less than 10 seconds without damage
To succeed in all this, the hull is designed with a deep “V” line and is built entirely of aluminum. Thanks to these features, combined with the pair of 435 horsepower engines, the 47 foot MLB is able to develop up to 25 knots top speed with 22 knots cruising speed. Up to 30 people can be embarked on board, plus 4 crew members.
To control the hull in all conditions and situations there are also four different driving positions: two in the closed deck and two outdoors.
