Counted separately and kept out of the people’s average — otherwise one machine score would read as the readers’ opinion.

ColRegs: Nav Lights & Shapes serves a very specific job: helping people learn the navigation lights, day shapes, and rule set behind COLREGs. By our assessment, its strength is that it turns a dense maritime code into something you can rehearse in small chunks, which is useful when the problem is recognition under pressure. The downside is that this is study material, not a full seamanship course, so it only covers one slice of the subject. In use, it probably feels like drilling symbols, meanings, and patterns until they stop blurring together. It sits closer to an exam aid than to a general boating guide.
