Correction for Leeway - Estimated Position

[fryewe]

Looked through the whole thread again...wanted to point out that heading is where the ship is pointing, and can be measured in either true or magnetic, and course is the direction you are trying to go. For example, your course can be 090M, and you can be heading 095M when you check the instrument you are using to steer...and your course can be 090M, and your heading could be 085M when you check the instrument. The course didn't change because you are still trying to go 090M. Your heading is always changing, wandering about the course you are trying to steer for reasons noted earlier.
