What do call a team of oarsmen?

Answer 1

there is no such boat that exists. in rowing there are single man boats (1x or referred to as a single) a 2 man boat (referred to as a double or a pair) a 4 man boat (a four) or an 8 man boat (an eight). including the coxswain there can be a 5 man boat in a four but not six

Answer 2

A crew
