Rudder bearing
Rudder bearings on sailing yachts: play, moisture paths, survey checks, and FairHelm limits versus claiming skeg boats never fail.
What this is
A rudder bearing is the bushing or bearing set that supports the rudder stock as it turns. Wear shows as play, stiffness, noise, or water at the tube.
Anchor
Skeg-hung and spade rudders both use bearings. FairHelm sea trials include slow reverse and helm feel. On the hard, surveyors check stock play and seals.
FairHelm judgment
FairHelm judgment: "skeg" is not a synonym for "no bearing work". Excess play, grinding, or wet tubes are price and survey items. Do not skip rudder checks because the brochure praises protection.
Limits
We do not invent hours-to-failure. Material, alignment, and grounding history dominate. A named surveyor should grade play for that installation.
FAQ
Q: Do skeg rudders eliminate bearing maintenance?
A: No. Bearings and seals still age.
Q: Is some helm play normal?
A: Slight feel can be normal. Excess play or grinding is not. Ask the surveyor for thresholds on that boat.
Q: Can I judge bearings from dock photos?
A: Rarely. Need hardstand or haul-out inspection.
