A double scull, also abbreviated as a 2x, is a rowing boat used in the sport of competitive rowing. It is designed for two persons who propel the boat by

sculling Sculling is the use of oars to propel a boat by moving them through the water on both sides of the craft, or moving one oar over the stern. A long, narrow boat with sliding seats, rigged with two oars per rower may be referred to as a scull, its ...

. In contrast to the combination of the coxed pair, in which the distribution of the riggers means the forces are staggered alternately along the boat, the symmetrical forces in sculling make the boat more efficient and so the double scull is faster than the coxless pair. List of world records in rowing A double sculling skiff has a similar layout to a double scull and is rowed in a similar way, but usually has a cox as well as two rowers. It is clinker built with fixed seats and thole pins and can be skiffed for leisure purposes or for the sport of skiff racing.
