The correct answer to the question asked is the current is 5-mph, except in the real world of boating in the Weirs channel, you need to consider the different drag coefficient for each boat.

A 16' fishing boat with a 40-hp outboard can weigh 800-lbs, while a 27' cruiser with twin 450-hp inboards can weigh maybe 10,000-lbs. The length, weight, and surface friction work together to determine the drag coefficient, and how each boat is effected by the 5-mph current, plus the hull is effected by the wind, too.
