Maintenance Tips

A Suggested Check List for Maintaining Your M242

Standing Rigging

  1. The clevis pins at all bottom locations in the standing rigging deform. Replace them regularly.
  2. Are all your ring dings and cotter pins sound?
  3. Are the shackles sound?
  4. Are the nuts on the bottoms of the U bolts that the shrouds anchor to sound? Are they lock nuts?


  1. Check that the jib halyard block is free to rotate and that it is still properly attached (ring ding or cotter pin).
  2. The spinnaker halyard exit box, above the hounds, wears out every 2 or 3 years. When it does, the spinnaker is hard to hoist or drop and the halyard chafes.
  3. Check the screws that hold the gooseneck and Vang anchors to the mast for tightness about every 10 or so outings (several times each summer). Once the screws get loose, they break.
  4. Check that the screws holding fittings to the mast are snug, Use Loctite to prevent corrosion and keep them snug.

Boom, Deck & the Rest

  1. The outhaul cleat wears out. You’ll know, it won’t hold the line any longer.
  2. Lubricate the winches every year, no matter how little use they get.
  3. Water gets between the hull and the liner if your mast boot leaks. (You find water at the base of the mast after a rain) It can come out around the seal for the kelp window and make you think you are sinking. It is reasonably easy to sponge or bail out, if you have the plastic storage bins, or access holes, in front of the main bulkhead.
  4. Lifting tackle, how much sunshine has fallen on it? Make sure the lifting eye nut is in good condition.
  5. Look over your running rigging, sheets, furling line and so forth.  Is there chafe? Check the jib halyard tackle and furling line in particular. How much sun damage is there on your halyards and topping lift? When they get badly faded (check the difference in color on the line where it is mostly inside the mast vs. outside) or they look and feel like cotton (soft and fluffy on the surface) they are about ready to break.  Replace them early.
  6. Check the universal joint on the tiller extension.
  7. Charge your battery approximately once a month, depending on use.
