When shifting to a course where the wind...

🔍 Key Concepts

• How easing (loosening) the mainsheet changes the angle of the boom to the wind • What happens to the shape and position of the mainsail when sailing with the wind more from astern (broad reach or run) • Difference between controlling sail shape/tension versus moving the sail up or down the mast

💭 Think About

• Picture the boom’s position when the mainsheet is tight versus when it’s eased as the wind moves further aft. Does the boom move toward the centerline or outboard? • Think about how a sail captures wind when it is more perpendicular versus more aligned with the wind. What boom position gives the sail a better ‘catch’ of a following wind? • Ask yourself which of the options describes something that is actually controlled by the mainsheet, and which describe things that other lines (like the halyard) would affect.

✅ Before You Answer

• Verify what line is normally used to raise or lower the head of the mainsail (is it the mainsheet or the halyard?). • Consider whether easing the mainsheet would make the boom more in line with the boat’s centerline or let it swing outboard. • Check which option best matches the idea of presenting more sail area to the apparent wind coming from astern.

When shifting to a course where the wind comes more from astern, what will easing the mainsheet accomplish?

It will bring the boom more fore and aft

It decreases the force needed to haul on the mainsheet

It allows the sail to catch more wind

It will bring the head of the sail down from the top of the mast
