[Rhodes22-list] Loose centerboard

[Michael D. Weisner]

Hi Doc,  ("distal end" gave you away)

My '81 Rhodes has never "clunked" - Stan had originally placed hitech shock 
absorbing materials alongside the centerboard which were probably removed by 
someone when your boat was serviced.  If you look closely at the area in the 
hull that "receives" the centerboard pin, you will find a V shaped recess on 
each side of the centerboard trunk.  The pin sits at the vertex.  Above the 
pin should be a pair of 5/8" garden hose shims that prevent the pin from 
rising in the groove and also damp out the side motion of the board.  No 
movement - no clunks.  Yup, just some old pieces of garden hose.
