Chart Plotting Lab
The plotting questions trip up more OUPV candidates than any other section. This is hands-on practice on a universal plotting sheet — lay a course, read true bearing and distance, and solve set-and-drift current triangles. Unlimited auto-graded problems.
What you’ll drill
- Course & distance — plot a leg and read the true course and nautical-mile distance off the grid.
- Set & drift — vector the current against your water track to find course and speed over ground.
- Unlimited randomized problems, auto-graded to exam tolerance.
