I purchased a freelance software from Hawspipe, and everything was going smoothe until i opened up the navigation section. Bunch of terrestrial stuff thats ive not done before. Sunrise, sunset, chronometer error etc… just stuff im not familiar with, and the reference it gives me is to bowditch, and i am a bit overwhelmes. Anyone have any suggestions on how i can get through this part of the test? Ive asked a couple buddies that are academy grads, and they cant remember the stuff either. I dont have the resources to pay 2000.00 for a prep course, and take that time off work. Im doing all of this on my own dime. Any help would be greatly appreciated. Thanks in advance.
