Use 'Em or Lose 'Em
Whether cruising or racing (rare, but known to have happened for us at least eight times in the last 20 years!), we use them all. As many have said, that's what they are there for.traveller - constantly, we have a nice wide traveller with the improved Garhhauer 6 part system, used with vang and mainsheetmainsheet - used with the traveller and the vang to get optimum twist and angle of attack, as well as to set the leach telltales streamingjib halyard - rarely reset with roller furling, use backstay tensioner insteadouthaul - Catalina outhauls are a joke (in boom, no purchase); added extra block outside, only adjust when wind strength varies considerablycunningham - added one when I bought the boat, couldn't do without it to keep the luff tight when the main halyard's all the way up (our main really fills the space completely from the top to the boom, and when the wind pipes up, the cummingham is the only luff tensioner we have)boom vang - Garhauer rigid, just greatmast bend - added a new Garhauer backstay tensioner last year, only used to tighten the luff of the jib. Catalina masts are not fractional, and they're telephone poles, they DO NOT bend.leech cord - used regularly, keeps popping out when we tack, needs a new cam cleat, very hepful to avoid leach flutterSeems to me that this generic, and useful question, has "subsets" that are not necessarily applicable to all boats (i.e., mast bend)
