exactly the same as the original windvane. If it does
not, adjust the dimensions until it does.
• CAUTION:evenacoatofpaintcansignificantly
add to the weight of your windvane. The painted
windvane must weigh exactly the same as the
original it is to replace.
• Thecounterweightismatchedtotheweightofthe
original windvane. Using a windvane of a different
weight will reduce the sensitivity of the system and
impair steering quality, especially in lighter airs.
• Thewindvanemaybenomorethan50g/1¾oz
lighter than the counterweight. It must never be
heavier than the counterweight!
4.9 WINDVANE TELLTALE
• Therecomesapointwherethereisjusttoolittle
wind to move the windvane. The fluttering of
the windvane telltale, a strip of spinnaker cloth
attached towards the upper trailing edge of the
vane, provides that little extra steering impulse and
extends the range of conditions over which the
system can sensibly be used.
