Hi
The PARKER27 I own does not have any anodes, except for the one in the yanmar 1GM10 engine. 
 I have been  puting on shaft anodes  but noticed some vibration. This year I was wodering weather to fit on a hull anode ,
 and not to bother with the shaft one.
Is this a bad idia?
The boat was only part finished by Parkers.
