Rope clutch
Rope clutches on sailing yachts: holding lines under load, wear signs, survey checks, and FairHelm limits on assuming new clutches fix old rope.
这是什么
A rope clutch (jammer) is a cam or wedge device that holds a line under load so the crew can take the line off a winch or free a hand while the line stays secured.
Anchor
Organiser banks of clutches are standard on cruising boats FairHelm sees in Northern Europe. Wrong line diameter, worn cams, and cracked bases show up after seasons of wet, sandy sheets.
FairHelm judgment
FairHelm judgment: clutches that slip under working load, cracked housings, and mismatched line sizes are survey items. A neat bank of black clutches in a photo does not prove cam bite. Test critical halyard and reef lines under controlled load.
Limits
We do not invent holding-load numbers for every clutch model here. Follow maker diameter and load guidance for that unit.
常见问题
Q: Is a clutch the same as a jammer?
A: Names overlap in practice. Both hold line. Check the specific model behaviour under load.
Q: Can new rope fix a slipping clutch?
A: Sometimes diameter helps. Worn cams still slip. Inspect both.
Q: Should every line have a clutch?
A: Layout depends on the boat. Critical loaded lines need a planned hold method.
