The range of directions into the wind, where a sailing craft cannot sail is called the [[:wiktionary:no-go zone|''no-go zone'']].<ref name="Complete">

A craft passing through the no-go zone to change tacks from one side to the other, must maintain momentum until its sails can draw power on the other side. If it remains in the no-go zone, it will slow to a stop and be ''in irons''.<ref name="Jobson">{{cite book |last=Jobson |first=Gary |url=https://books.google.com/books?id=mKTrrP3wA-cC&q=Johnson,+Gary+(2008).+%22Sailing+Fundamentals%22 |title=Sailing Fundamentals |publisher=Simon and Schuster |year=2008 |isbn=9781439136782 |location=New York |pages=72–75}}</ref> This is called ''missing stays''.

A  craft stopped in the no-go zone is said to be in irons.
