A quad scull, sometimes known as a quadruple scull, is a rowing boat used in competition rowing. It is intended for four individuals who scull with two oars in each hand to move the boat. There are several types of boats that can be referred to as quads.
The number of oars per person varies depending on the type of boat. In a coxed quad, one person sits in the bow and steers with an oar in each hand. The others sit in the stern and scull with two oars in each hand. In a double quad, three people usually sit in the boat, with one person rowing in the bow and steering with an oar in each hand, and the other two sitting in the stern and using two oars in each hand. The term "quad" also may refer to the number of people in the boat, without reference to their relative positions. For example, a quad of eight people would consist of four pairs of twins or sibling rows.
Quads are typically between 18 and 22 feet long and weigh around 1500 pounds. They have flat bottoms which make them stable on water but not very fast (about 15 miles per hour).
There is no specific national body that controls the development of quad racing.
Sculling in fours. The length is 13.4m, and the weight is 52kg. Men's and women's events After the eights, the quickest boats have eight blades and four rowers. These are known as sculls. The rest of the boats have six blades and two rowers or four blades and three rowers.
Quads have longer blades and so can reach higher speeds. They also require more skill to drive. An eight-man boat can go faster than a quad because it has more crew members and therefore more weight over the blade. A quad cannot go as fast because it is easier to capsize than an eight.
In practice, most regattas offer choices of both types of boat. The decision will depend on the size of the field and the type of race being held. In general, quads are for smaller courses up to about 500 meters long, while eights are usually used for longer races.
However, in some cases you may come across older races where only quads are allowed. Also, in major regattas such as the Olympic Games, only quads are permitted because they provide a closer race. Eight-man boats tend to be wider and so can hold more people. This means that they are likely to have more sponsorship logos visible during the race.
Currently, men and women participate in six events. These are the single, double, and quadruple sculls, as well as the lightweight double scull, eight, and coxless pair. Men also compete in two more events: coxless fours and lightweight coxless fours. Women can enter up to five events. The exceptions are the heavyweight rowing events, which are only for men, and the mixed double sculls, which are an open event for both men and women.
In ancient Greece, there were only three types of boat used for naval warfare: the coracle, the trireme, and the rowing ship. The coracle was a small, round boat with no more than 1 or 2 meters (3-6 feet) of depth. It was used by warriors on land or sailors at sea. The trireme was a larger version of the coracle that was used for battle by soldiers from different cities who wanted to avoid fighting each other directly. They would instead hire champions from each city to fight for them. Finally, the rowing ship was the largest type of boat used by Greek and Roman navies. It was usually made out of wood and had up to 70 oars per side. Rowers sat facing forward, one behind the other, using their legs to power the boat along the river or ocean. There were two types of rowing ships: those that were sailed by slaves and those that were not.
