USCG Inland Construction Tender
An inland construction tender is a type of ship used to build and service shore structures such as piers and buoy trestles. It is also used to maintain buoys and aids to navigation. Less frequently, they may be used for law enforcement, environmental, icebreaking, and search and rescue operations.

Navigation Aid
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.Bowditch, 2003:799. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. History In the European medieval period, navigation was considered part of the set of '' seven mechanical arts'', none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open-ocean navigation; it was b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The United States Coast Guard (USCG) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces and one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest and most powerful coast guard in the world, rivaling the capabilities and size of most navies. The U.S. Coast Guard is a humanitarian and security service. It protects the United States' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across vast territorial waters spanning 95,000 miles of coastline and its Exclusive Economic Zone.

USCG Coastal Buoy Tender
The United States Coast Guard commissioned a new Keeper class of coastal buoy tenders in the 1990s that are 175 feet (53 m) in length and named after lighthouse keepers. Keeper-class cutters serve the Coast Guard in a variety of missions and are tasked with maintaining aids to navigation (ATON), search and rescue (SAR), law enforcement (LE), migrant interdiction, marine safety inspections, environmental protection and natural resources management. Keeper-class cutters are also used for light ice breaking operations. These vessels are 175' long and replaced the World War II era 180', 157' and 133' tenders. The new class of buoy tender cut crew size from 50, 35 and 26, respectively, to 25, saving the already cash-strapped Coast Guard financial and personnel resources. Keeper-class cutters were built by Marinette Marine of Marinette, WI. Keeper-class cutters are equipped with mechanical Z-drive azimuth thruster propulsion units instead of the standard propeller and rudder confi ...
