This is an 18 hours classroom course. Former "Coastal Navigation" is now split into "Basic" and "Intermediate" portions.
During the course we expand beyond objectives of the "Basic" and also cover much of the "Intermediate".
Still, the accent is on the "Basic" which is a prerequisite for on-water Intermediate Cruising Standard.
To get the certificate a candidate must pass written test and a chart work (70% pass mark). This is an open-book exam.
You can also challenge "Intermeditate" which is a closed book exam.
Beside classroom hours, be prepared for significant homework.
Navigation is not difficult, but knowing how is not enough.
It is the "small error" that leads to accident, so practice, practice, practice. There are no prerequisites to attend this course.
