Left and Right didn't have their modern meaning back then. In Old English riht meant straight, as in direct or not bent. It later assumed the meaning of correct as in right and wrong. Lyft meant weak. Their reference to handedness seems to have been incidental. It seems odd to us to talk about the 'straight' and 'weak' hand, but to them it made sense, but maybe not to talk about the 'straight' or 'weak' sides of a boat.
The concept of left and right hands was not very commonly used historically. It wasn't important to most people. During the English Civil War many recruits didn't know which hand or foot was left or right. During marching training instructors used to stick some hay in one boot and straw in the other for each recruit and call out "Hay, Straw, Hay, Straw".
