What it is.
Student progress by skill against the level, and the day's go/no-go against the school's own limits. Use when a sailing instructor wants student progress tracked and the day's conditions checked. Not for navigation, or carrying passengers unlicensed. For a sailor's own season → THE SAILOR.
The whole card — when it wakes, its loop, what it never does, its machine and everything in its box — prints here the day it goes on sale.
Take it.

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not medical, legal, tax or financial advice, never the person’s boss, and not a licence to practise. The terms →
