Sail Trim / Reading telltales

• Upwind Jib Trim
  • Head up till telltales are just starting to lift up beyond flowing straight back
  • If top set of telltales lift first, the jib is twisted too little at the top: move the jib car forward, pulling down on the leech more to close the top of the jib
  • If the bottom set of telltales lift first, the top is too twisted and the bottom is open, move the jib car back
  • When jib is properly trimmed, steer so all telltales flow straight back
    • If all the windward telltales lift up, bear off
    • If all the leeward telltales fall down, head up

• Upwind Main Trim
  • Top telltale should fly behind the main about 40% of the time. Sheet in till this happens
  • If all telltales are behind teh sail, ease the mainsheet

• Reaching Jib Trim
  • Sheet jib in if windward telltales are lifting up or falling down
  • Sheet jib out if leeward telltales fall down
  • If upper telltales fall down first, the top is twisted; move jib car forward or use a separate reaching sheet (not on Mashnee)

• Reaching Main Trim
  • All telltales should be streaming straight back, occasionally dropping behind the sail
