In towing it is desirable for the tug and the MODU to ride wave crests simultaneously because __________.

Correct Answer: Option D — shock loading on the tow line is reduced

Riding wave crests simultaneously prevents the tug and MODU from falling into troughs out of phase, which causes severe snap loads. Matching wave positions minimizes severe catenary fluctuations and drastically reduces dangerous dynamic shock loading on the towing gear.
