The effect of ocean currents is usually more evident on a rig being towed than on a tug navigating independently because the __________.

Correct Answer: Option D — speed of the tow is less

Towed rigs exhibit significantly lower operational speeds and vastly increased wind and current cross-sectional area compared to independently propelled tugs. Consequently, ocean current vectors exert a much greater proportional set and drift effect on the sluggish rig than on the powered towing vessel.
