🔍 Key Concepts

• Jibe (gybe) in strong wind creates a sudden shock load on the rig when the boom and mainsail snap across • Which stays control fore‑and‑aft support of the mast (forward vs aft) vs which parts mainly hoist sails • Difference between a stay (supporting the mast) and a halyard (hoisting a sail) in terms of shock loading

💭 Think About

• When the boom slams across in a strong jibe, which direction is the top of the mast being pulled, and which stay must resist that sudden pull? • Of the options listed, which component is normally under the highest, most constant tension and will also see the greatest instantaneous increase in load during a violent jibe? • Which of these parts is more of a working line you adjust, and which are structural supports that, if they fail, would likely be from overload during a sudden maneuver?

✅ Before You Answer

• Identify which options are mast-supporting stays vs which is primarily a hoisting line • Visualize the sail plan during a jibe: wind from aft, boom crossing the stern — which stay is shocked hardest as the sail fills on the new side? • Eliminate any part that is not primarily taking large fore‑and‑aft shock loads when the boom snaps across.
