How would the speed(efficiency) compare on a 20 ft boat with two good paddlers to a 15 ft boat with one good paddler ,same hull design and close to the same width?
On the paddlers ( the engine) would be the same guys.

Two paddlers will out due a single paddler any-day. It's like the Double mint Chewing gum ad , Double your pleasure double your fun , in this case double the paddling ability. Two paddles in the water sure beats one for getting down the river then with the 5 more feet in the boat... WOW ..

yep
