Updated Regularly

We always update the content according to the latest NTM's (Notice to Mariners) before a print run, or we include a printed addendum which includes any changes.

Our cover design includes the date of the most recent update and is often imitated. Don't be fooled by a subpar version with a similar cover.

Professionally Printed

Our version is in color, which is important when learning the color patterns of lights.

Includes a Record of Changes

We include a table of changes at the beginning of the book.

Easy to Find All Changes

Inside the book we underline and highlight all of the changes made to the edition.
