244. Which term is used to describe the dip in a towline that acts as a shock absorber?
The correct term for the sag in a towline that acts as a shock absorber is catenary. This curve naturally forms due to the line's weight and drag, allowing it to gradually absorb tension and reduce shock loads on the tug and tow. Other options are not standard seamanship terms for this specific function.
