### Instruction:
What is the role of the coxswain?

### Input:
The coxswain (or simply the cox) is the member who steers the boat using rudder strings, and coordinates the power and rhythm of the rowers, by communicating to the crew, often through a device called a cox box and speakers. The cox usually sits in the stern of the boat facing the rowers but in bowloaders, usually seen in the coxed four and coxed pair types of boat, the coxswain lies in the bow.

### Response:
A coxswain sits in the stern of a rowing boat. A coxswain steers using rudder strings and coordinates the rowers through speakers located throughout the boat.
