The ship

This term must be interpreted broadly and can refer to any structure floating in water. It is usually self-propelled but some, for instance, dumb barges and some offshore structures rely on tugs to move them. Others rely on the wind. Marine structures, such as harbour installations, are the province of the civil engineer.

The purpose of a merchant ship is to carry goods, perhaps people, safely across water. That of a warship is the support of government policy in the international field. Let us concentrate on the merchant ship. In ordering a new vessel the owner will have in mind, inter alia:

• a certain volume of cargo to be carried on each voyage;

• a range of ports from which the ship will operate;

• an average journey time.

Each requirement will have an impact upon the ship design:

• The type of cargo may be able to be carried in bulk or may require packaging; it may be hazardous or it may require a special on-board environment.

• The volume of cargo will be the major factor in determining the size of the ship. An additional factor may be the need to move the cargo in discreet units of a specified size and weight.

• The ports, plus any rivers and canals to be negotiated, may place restrictions on the overall dimensions of the vessel. Depending on the port facilities the ship may have to provide more, or less, cargo handling equipment on board. The ports will also dictate the ocean areas to be traversed and hence the sea and weather conditions likely to be encountered.

• Ship schedules will dictate the speed and hence the installed power. They may point to desirable intervals between maintenance periods.

How To Have A Perfect Boating Experience

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
