IV. Inspection and maintenance
A. INTRODUCTION
For the best performance, reliability and safety you should inspect periodically the rigging
and the mast. The following information will help you to know what to consider when inspecting a
mast.
B. MAST INSPECTION
1. Mast head: check the attachments of headstay, backstay,... for elongated clevis pin
holes, split pins and proper alignment. Check sheaves and pins for wear and ensure
that sheaves turn freely. Check for sharp edges where halyards exit. Inspect top of
mainsail track for wear. Check that all fasteners, rivets, and screws are tight. All Dee
shackles should be seized to prevent screw pin from backing out.
2. Headstay and furler: the top of the headstay furler should be inspected for damage
caused by halyard wrapping. Check for proper height of the halyard swivel. Check
upper terminal on wire or rod for fatigue. Inspect furler hardware for loose or
missing fasteners. Make sure the system rotates freely.
3. Upper, intermediate, and lower shrouds: Check all terminals for signs of fatigue and
cracks. Check tangs and surrounding areas for signs of stress or cracks. Inspect clevis
and split pins for wear. Check shrouds or terminals at the ends of the spreaders.
4. Backstay: Check terminals for fatigue. Check backstay turnbuckle or hydraulic cylinder
for proper function.
5. Spreaders: Check spreaders for bents, dents. Check leading and trailing edges of
spreader for wear caused by runners and/or inner forestays. Add chafe protection
locally to runners. Check that the spreader bases are secure. Make sure shrouds are
securely attached to spreader tips with tip plate or lashing.
6. Check sail track fasteners if the track is mechanically fastened to the spar. Loose
rivets or screws could prevent the sail from dropping.
7. Running backstays, inner forestay, and baby stay: Inspect terminals for fatigue and
proper alignment. Check toggles and clevis/cotter pins.
8. Check the bearing point of the mast plug on the base is centered about 40% from the
back of the mast.
9. Check boom and vang goosenecks for fatigue and elongated holes. Check for loose
fasteners.
