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.
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.

A harbor pilot is a person who takes control of a seagoing ship when it is entering or leaving port. He is expertly familiar with all the channels, shoals, currents, tides, and regulations of his particular port, and is essential to safely steer the ships in and out. It is an ancient and exclusive profession, often passed down from father to son*. In old days, the top two signal flags at right were used by ships entering and exiting a harbor to call for a pilot, while the bottom flag indicated "pilot on board."

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.

The schooner barge was the final development of the working sailing ship. The design originally evolved in the 1870s on the Great Lakes, where it was found that sailing ships could be more profitably towed from place to place than sailed. No longer subject to the vagaries of the wind, such trips could be made on a scheduled basis, and with reduced labor costs. The idea spread into general use, resulting in the conversion of many sailing ships into barges. Ironically, most of the vessels that were converted to schooner barges were not actually schooners, but square-rigged ships. Square-riggers, with their large and expensive crews of skilled sailors, became uneconomical to operate in the face of ever-improving steam power, while more efficient schooners managed to compete for a few years longer.

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.
