Genoa
Genoa headsails on sailing yachts: overlap vs jib, furling wear, survey checks, and FairHelm limits on photo-only cloth judgments.
这是什么
A genoa is a large headsail that overlaps the mast when sheeted, giving more area than a high-clewed working jib of similar luff length.
Anchor
Roller genoas dominate used Nordic cruisers FairHelm surveys. UV strips, sacrificial covers, and leech lines age in the sun while the middle looks fine. Size number (135, 150) is a cut hint, not a condition grade.
FairHelm judgment
FairHelm judgment: shredded UV cloth, hooked leeches, and foils that will not furl square are survey items. A furled white sausage in a photo hides most cloth. Unroll for inspection when wind allows.
Limits
We do not invent sail-area percentages as universal "cruising" law. Rig and sheeting angles decide what overlaps well on that boat.
常见问题
Q: Is every roller headsail a genoa?
A: No. Some are non-overlapping jibs. Check overlap and clew height.
Q: Does a new UV strip mean a new sail?
A: No. Strips are often replaced on older cloth.
Q: Can I judge a genoa furled?
A: Only the cover face. Open it for seams and shape.
