A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying goods or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and tradition.

Everyone knows what a submarine is - a ship that can go underwater. Hardly needs any explanation. Unless you're in the US Navy. By the Navy definition, only their modern, nuclear-powered boats ( all submarines are called "boats" ) are true submarines, designed to operate beneath the surface almost indefinitely. Anything else is merely a "submersible", tied to the surface by the need for fuel and air. Whatever.

A barge is a vessel that does not have its own means of propulsion ( usually. ) Barges are towed or pushed from place to place by tugboats, or anchored in place to serve as temporary work platforms, floating docks, or storage. Some barges are self-propelled, in a limited way. These are known as scows, and their limited propulsive power restricts them to protected waters without the assistance of a tugboat.

A tugboat is a small sturdy and powerful vessel designed to push or tow other vessels and barges

You will see them in every sizable port; smart, businesslike small ships, low in the water and surging out to a large inbound ship. Tugs represent power for pushing and pulling, an engine with just enough hull for adequate buoyancy. Thick fenders for close-quarters work, pushing a big ship alongside the quay against the wind, hauling her off at the end of a towing wire.

There are three basic types of commercial fishing vessels found in the Mid-Atlantic region: trawlers, seiners/gill-netters, and long-liners. A trawler or "dragger" operates by towing its fishing gear across the bottom. Weighted nets take bottom fishes, while cage-like steel dredges take clams and scallops. A seiner uses a floating net to encircle schools of surface-swimming fishes such as herring and tuna. A long-liner sets out miles of buoyed line with baited hooks to catch sharks, tuna, and swordfish. One could also add lobster boats and charter fishing or "head" boats to this list. And of course, dive boats.

A number of small warships are sunk in New Jersey and New York waters.

A subchaser was a small coastal patrol vessel of World War I or II. Subchasers were lightly armed and even more lightly constructed, mostly out of plywood, powered by two diesel (WWII) or three gasoline (WWI) engines. Roughly the same design was used in both wars - 110 ft long, about 100 tons. Almost a thousand were built over both World Wars, and several are lost in the waters around this area. Many private yachts and some larger fishing trawlers were converted to perform this function also, like the Tarantula and the Moonstone. Conversely, some subchasers were converted to other duties after the war, such as the Bronx Queen, pictured below in military trim. Real subchasers were designated SC-, while converted yachts were designated SP-, PY- ( patrol yacht ) or PYc ( patrol yacht - coastal. )
