Next step is to calculate leeway, and answer the remaining questions

This is what I surmised in Post #5... I had done this years ago, but appear to have forgotten.

Running Fix is now Lat: 41º 22.8'N Long: 71º 25.9'W
Close to the answer sheet's; 41º 22.35'N 71º 25.7'W

Course made good by my calculations is now 000ºm - answer sheet says 003ºm

This seems REALLY imprecise because I have no idea if the current or wind are helping or hurting my fix....
