Re: Sailboat Quality
What boats NEED to replace their chainplates every 10 years ?
SchockT's experience with his Santana30 not having a hint of chainplate issues after 33 years seems to be the more typical situation.
BTW - one of our Harbor daysailer owners also has a 50ft Swan circa 30 years old. His chainplates did need to be replaced due to corrosion.
The Schock Harbor 30 has a carbon fiber-epoxy-G10 stringer/ring frame that the SS-316 chainplates connect to. The thickened laminate extends 24" either side of the stringer to better distribute loads from keel-shrouds. It is a very very stiff system. The stringer and thickened laminate runs high enough up that the chainplates are never going to get wet. It turns out the Navy leadership 44s have a similar design approach.
