Fin is for stability.
Rudder is to compensate for crosswind, engine power etc. It controls the longitudinal axis around the vertical axis.
Your point? Its the same reason why multi-engined aircraft have a fin and rudder.
Although there are aircraft that don't have a fin and rudder.
My question was if you ever needed more rudder on a crosswind landing then on a TOGA V1cut with minimum V speeds in a jet (not talking about fancy improved climb speeds or flex takeoffs)?
