US Sailing Basic Keelboat Practice Test

Which term means a quick reefing method that secures a section of the mainsail to the boom?

Kedge off Jibe Keel Jiffy reef

Correct Answer:

Jiffy reef

Explanation:

This question is about reefing terminology—the fast way sailors reduce mainsail area when wind picks up. A jiffy reef is a quick method to reduce sail by securing a section of the mainsail to the boom, making the sail smaller without fully dropping and re-hoisting it. This lets you maintain better balance and control in stronger winds. Kedge off describes moving the boat with an anchor or line, not related to sail adjustments. Jibe is turning the boat’s stern through the wind, which is a maneuver, not a way to reef. Keel is the underwater ballast in the hull, not a sail-reducing technique. So the fast reefing method that secures part of the sail to the boom is the jiffy reef.
