Scout (autonomous Boat)
Scout is an autonomous robotic boat designed to complete the first autonomous transatlantic crossing. The project was started by Tiverton students Dylan Rodriguez and Max Kramers in 2010 with the goal of creating an autonomous craft to make the journey from Rhode Island to Sanlucar de Barrameda, Spain. After several iterations, Scout's first transatlantic attempt was launched from Sakonnet Point on June 29, 2013 but unfavourable weather conditions forced the team to recover the craft the same day. A second launch was made July 4, 2013 but after two days a technical failure forced another recovery effort and a redesign of parts of the vessel. The third attempt was launched during the early morning of August 24, 2013 and is currently in progress but has already earned the record for distance of an unmanned Atlantic naval voyage. Technical specifications Scout is based on a custom carbon fiber hull with a Divinycell foam core and measures 12.8 feet long, and 25 inches wide and weigh ...

Unmanned Surface Vehicle
Unmanned surface vehicles (USVs), also known as unmanned surface vessels, autonomous surface vehicles (ASVs) in some cases, uncrewed surface vessels (USVs), or colloquially drone ships, or robot boats, are boats or ships that operate on the surface of the water without a crew. USVs operate with various levels of autonomy, from remote control to fully autonomous. Some commercial USVs may utilize COLREGs-compliant navigation. USVs were used militarily as early as World War II for remote controlled target craft and minesweeper purposes, they are becoming more widely used in the twenty-first century for a range of purposes including oceanography and environmental monitoring, as well as cargo transport, and military applications. Various other applications are also being explored. In October 2022 during the Russian invasion of Ukraine Ukraine armed forces used 7 USVs and 8 UAVs in an attack on multiple Russian naval vessels at the Sevastopol Naval Base.

Sanlúcar De Barrameda
Sanlúcar de Barrameda (), or simply Sanlúcar, is a city in the northwest of Cádiz province, part of the autonomous community of Andalucía in southern Spain. Sanlúcar is located on the left bank at the mouth of the Guadalquivir River opposite the Doñana National Park, 52 km from the provincial capital Cádiz and 119 km from Sevilla capital of the autonomous region Andalucía. Its population is 68,656 inhabitants ( National Institute of Statistics 2019). Sanlúcar has been inhabited since ancient times, and is assumed to have belonged to the realm of the Tartessian civilization. The town of San Lucar was granted to the Spanish nobleman Alonso Pérez de Guzmán in 1297. Its strategic location made the city a starting point for the exploration, colonization and evangelization of America between the 15th and 17th centuries. Sanlúcar lost much of its strategic value after 1645 because of the disgrace of the House of Medina Sidonia, the general decline of Spain und ...

The Providence Journal
''The Providence Journal'', colloquially known as the ''ProJo'', is a daily newspaper serving the metropolitan area of Providence, Rhode Island, and is the largest newspaper in Rhode Island. The newspaper was first published in 1829. The newspaper has won four Pulitzer Prizes. The ''Journal'' bills itself as "America's oldest daily newspaper in continuous publication", a distinction that comes from the fact that ''The Hartford Courant'', started in 1764, did not become a daily until 1837 and the ''New York Post'', which began daily publication in 1801, had to suspend publication during strikes in 1958 and 1978. History Early years The beginnings of the Providence Journal Company were on January 3, 1820, when publisher "Honest" John Miller started the ''Manufacturers' & Farmers' Journal, Providence & Pawtucket Advertiser'' in Providence, published twice per week. The paper's office was in the old Coffee House, at the corner of Market Square and Canal street. The paper moved many t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulb Keel
200px, Flat Keel bulb A bulb keel is a keel, usually made with a high aspect ratio foil, that contains a ballast-filled bulb at the bottom, usually teardrop shaped. The purpose of the bulb keel is to place the ballast as low as possible, therefore gaining the maximum possible amount of leverage and thus the most righting moment. An example of a class of boats that use a bulb keel is the International 110 racing class, which uses a 300 lb (136 kg) cast iron bulb keel on a boat whose minimum racing weight is 910 lb (414 kg). Since bulb keels work best on long, thin keels or daggerboards, they are generally not used on sailboats intended for shallow waters, but are most often found on offshore racing craft. Daggerboards built like bulb keels are often referred to as "lifting keels", and they can be retracted into the boat to reduce the draft, and to allow the boat to be loaded onto a trailer. Lifting keels are also more likely to be found on craft built for sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trolling Motor
A trolling motor is a self-contained marine propulsion unit that includes an electric motor, propeller and control system, and is affixed to an angler's boat, either at the bow or stern. A gasoline-powered outboard used in trolling, if it is not the vessel's primary source of propulsion, may also be referred to as a ''trolling motor.'' The main function of trolling motors is to keep the boat running at a consistent, low speed suitable for trolling. Trolling motors are often lifted from the water to reduce drag when the boat's primary engine is in operation. Uses * Trolling for game fish; a motor used for this purpose is usually a secondary means of propulsion, and mounted on the transom alongside the primary outboard motor or on a bracket made for the purpose. * Auxiliary power for precision maneuvering of the boat, to enable the angler to cast his bait to where the fish are located. Trolling motors designed for this application are typically mounted in the bow. History An 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithium Iron Phosphate Battery
The lithium iron phosphate battery (LFP (lithium ferro-phosphate), or Li-IP) is a type of lithium-ion battery using lithium iron phosphate () as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their lower cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. LFP batteries are cobalt-free. As of Q1 2021, LFP type battery market share reached 24.1%, with Chinese manufacturers holding a near monopoly, and is expected to rise further to surpass NMC type batteries in 2028. The energy density of an LFP battery is lower than that of other common lithium ion battery types such as nickel manganese cobalt (NMC) and nickel cobalt aluminum (NCA), and also has a lower operating voltage; CATL's LFP batteries are currently at 125 watt hours (Wh) per kg, up to possibly 160 Wh/kg with improved packing techn ...

Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
