Cape Horn WV info

Talked to a cruiser back from 4 years in the south pacific on an 
Oceanis 43 with a Cape Horn windvane. He re****ts the vane worked well 
with a couple of exceptions.
  1) The tube transversing the transom is not watertight and following 
seas do push water thru it.
  2) His unit started sticking where the rod p***** thru the plastic 
bu****ng. After several emails with Cape Horn, they finally admitted that 
the plastic they used had a tendency to absorb water and swell up to 15%.
  The fix was to disassemble and bore out the bu****ng using the proper 
sized drill.
  Cape Horn told him the were "thinking" of going to delrin or something 
else.
  His unit is 5 years old and he didn't know if they have since upgraded.
  The only other problem he encountered was a failed block. He re****ted 
no abraded control lines.
  BTW, his unit was installed by a Cape Horn rep.
