A knot/hour is an acceleration. You are using modern terminology. In the days when they tossed a real log overboard and measured time by singing a song. Issac Newton was still 100+ years in the future and no one new calculus or what "acceleration" was. Most sailors could not count to 100 out load and many could not even write their own name. I doubt they used the terms as precisely as we do now. History seems to only teach us about the top tier, the Royal Navy and their educated officers and the explorers like Cook and Magellan. Most were not nearly at that level of competence. Most captains followed "cook book" like directions and did not understand the theory.
