When the rower uses one oar on one side, it is called sweep rowing that the single oar is called a "sweep" oar. [1] When the rower uses two oars at the same time, one on each side, it is called sculling, and the two oars are called a pair of "sculls". Typical sculls are around 284 cm - 290 cm in length — sweep oars are 370 cm - 376 cm.
Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.
In fresh water terminology, "rowing" is the use of one oar per person, whilst "pulling" denotes each person using two oars. [1]: 135 Traditional boats propelled by oar are fitted with thwarts - seats that go from one side of the hull to the other, as well as forming part of the hull structure. A boat that is "double banked" has two crew members ...

Three levels of oars was the practical upper limit, but it was improved on by making ships longer, broader, and heavier and placing more than one rower per oar. Naval conflict grew more intense and extensive, and by 100 BC galleys with four, five or six rows of oarsmen were commonplace and carried large complements of soldiers and catapults.
The vessel was designed with a high, almost vertical, stern and stem. It proved difficult to fit in more than one rower per oar and the thwarts were too close together. Less constricted images from the fourteenth and fifteenth centuries show vessels which are longer and larger. [26]

In computer graphics, a line drawing algorithm is an algorithm for approximating a line segment on discrete graphical media, such as pixel-based displays and printers. On such media, line drawing requires an approximation (in nontrivial cases).
