To avoid confusion sweep and scull boats are named differently, a four man sweep boat is called simply "four", while a four man sculling boat is called " Quadruple scull" or just "quad"
The abbreviation for sculling boats is the number of rowers in the boat followed by an "x" to denote a scull then a "+" or "-" to denote coxed boats to coxless boats
Coxless Quadruple scull is "4x-"
"I can't stand sculling around like this all day. I need to accomplish a task!"
