Assume that there are two canoes of identical design, materials, etc. The "only" difference between them is that one weighs 28 pounds and the other 34 pounds fully rigged. Both canoes are not affected by the weight difference in terms of the strength and the long-term integrity of the canoe. Assume also that both canoes are paddled by the same paddler (assume he/she weighs 170 lbs) and under the same conditions.
What would you expect to find when the canoes are raced in (i) flat water, (ii) upwind and (iii) downwind conditions under sprint and endurance events?
Is 6lbs a detriment or contributor to performance in terms of who wins the race?
