Curling stones must be the correct shape and size: about 40 pounds in weight, a maximum circumference of 3 feet 36 inches wide, and minimum height of 4. The curling lines and circles are also highly regulated. The hacks, back lines , tee lines, Free Guard Zones, hog lines, and house circles all have to follow exact measurements, for example, the radius of the largest circle is exactly 6 feet, while the button is only 6 to 9 inches. In all, a full ice sheet measures up to feet by The brooms, footwear, and optional stabilizers may also be subject to review by the competition organizers if needed, although gaining a competitive advantage via equipment is highly frowned upon by the culture and spirit of curling.
Within each curling team, there is a certain order in which curling throws are made. This is similar to a batting order in baseball or softball. This order is as follows:. The idea is that the lead has the easiest shot since there are less stones on the ice at the time of the first shot , and the shots increase in difficulty for each subsequent throw.
This means the skip has the most difficult shot because there are already several stones on the ice by the time it is the skip's turn to throw.
This is why the skip is often the most experienced player on a curling team. After the lead throws, they will sweep for the next three of their teammates' shots. The second also sweeps for their other three teammates.
The vice takes up the "target" position for the skip and sweeps only for the first two throws. The skip is the target for the three other players. This position requires holding a brush to indicate where a stone should be thrown while telling one's teammates where and how to sweep. One of the most basic rules of curling is the hog line rule: a player must release their stone before it reaches the hog line.
The delivering side's hog line is located 33 feet from the starting hacks, 72 feet to the next hog line, and a total of 93 feet to the far end tee line. The hog line rule forces players to throw the stone farther than they carry it, increasing the level of difficulty and making players rely more on skill and precision than strength or speed.
If a stone is not released before touching the hog line, the non-offending team removes it and replaces any stones it may have affected. The throwing team will almost always acknowledge their mistake and the error can be courteously rectified. The throwing team is also allowed to collect the stone before it reaches the tee line if it has violated the hog line rule. Five times as popular as in the US. Because the barbell curl performs the same motion as the dumbbell curl, except with both hands, the average curl weight for this type of exercise would be approximately half that per arm or 40 pounds for men and 20 pounds for women.
So why does the curling stone curl the way it does? Wet friction, say the scientists. However, for the curling stone, the liquid layer reduces the friction at the front so that it is less than the friction at the back. Thus a clockwise-turning stone curls to the right. Only one team can score during a curling end.
The team with the most stones closest to the curling bullseye — the button — is awarded points. So if, after 16 stones are thrown, Team A has a stone right on the button, and Team B has a stone a few feet off the button, Team A scores a point. The hammer for the first end is awarded to the team that puts two rocks closest to the button in a pre-game shootout. Officials measure the combined distance. As the match wears on, the hammer goes to the team that did not score in the previous end.
It uses innovative technology to detect a magnetic strip frozen into the ice at the hog line and a bare hand touching the handle. Circuitry in the handle turns on green lights after a valid release or flashes red lights if a violation has occurred.
The system is activated when the rock is tilted for cleaning. The last shot of an end is called the hammer. The team that shoots last has the advantage. It is considered a victory for the team without the hammer if they make the other team take only one point. For curling clubs that play on arena ice which is not specifically dedicated for curling , it is important to set up the ice quickly so that all eight ends can be fit into the curling club's ice time slot.
There are some cases in which eight ends cannot be completed due to timing restrictions. Ten end games are the most common for competitive national and international play, and usually take about two and a half hours to play recall that 15 minutes per end is being budgeted. As a new curler, you will probably not play ten end games. However, you will definitely see them on television. This is called a blank end. The teams take it in turns to deliver their stones from the Hack at one end of the sheet to the house at the opposite end.
Players must release the stone before the Hog Line for the stone to be considered in play. Stones which do not pass the hog line at the scoring end of the sheet are removed from play.
When an end is complete, the next end is played in the opposite direction. After all stones have been delivered to the scoring end of the sheet, the players themselves calculate the score. Curling is played over ten ends, however in some formats and competitions this may be reduced to eight ends. Teams can concede their game earlier than the defined number of ends according to the rules of the competition.
The teams with the most points at this stage wins the game. Before a game of curling begins, teams decide who will have what is called the Hammer or Last Stone Advantage. In championship curling this is decided by a draw to the button with two players from each team delivering a stone as close as possible to the centre of the house — one stone is delivered clockwise and the other counter-clockwise — and the distance from the stone to the centre being measured.
If a team has the last stone advantage, it means they can deliver the final stone of an end and have an advantage to score at least one point and potentially win that end. When a team scores, they lose the last stone advantage and the hammer passes to the opposing team for the next end. Teams generally try to score more than a single point in an end and will, therefore, sometimes blank an end, ensuring that no stones are lying in the house after the last stone is played.
This means they get to keep the hammer for the next end. However, in mixed doubles, a blank end also causes the hammer to be passed to the opposing team. In mixed doubles, teams have the right to use a power play once in every game.
In most ends, the pre-placed stones, will be positioned so that the team with last stone advantage will start the end with one stone at the back of the four-foot circle red in this example.
