For me, fiberglass
encapsulated stainless is a prescription for premature failure. The problem with SS plates is usually water
intrusion at the deck
creating an oxygen depleted area as the plate passes through the deck
. Crevice corrosion
is the result of electrolyte in oxygen deprived environment
. If the Chain Plate
is encapsulated in FRP, the whole chain plate
will be subject to corrosion
, not just the inter deck region, because of trapped water
. The inter deck region will be even worse as any water that seeps in will be trapped by the glassed in area below keeping the part constantly soaked in brine. Add PITA job of replacing the chain plate and the near impossibility to inspect makes glassed in chain plates a recipe for disaster. Really amazed that a supposedly high end builder
as Island Packet
would do such a stupid construction practice.
Go external with your chainplates. Use the money
saved by doing away with the original dumb design and get Titanium Chain Plates.
