Description

Many mariners struggle with learning Secondary Ports on their RYA course, but this sheet is a simple graphical method to show how easy the calculations can be.

The A4 laminated sheet has two sides, with the first side showing how the information you need is laid out and what it means, as well as a worked example of time differences. The second side has a worked example of height differences, with space left for your own calculations.

Matt encapasulation means that a 2B pencil may be used directly on the plastic.
