What this video covers
The original 3/16-inch by 1 1/4-inch chainplates on an Alberg 30 show significant corrosion and insufficient sizing.0:11 Replacing these requires upgrading to larger plates and increasing bolt diameter.0:23 The installation process involves adding plywood reinforcement to the existing knees, which are then glassed in to provide structural support.0:54 To ensure proper alignment against the bulkheads, the new chainplates are set into thickened epoxy while wrapped in plastic to prevent bonding.2:38 Once the epoxy cures, the plates are drilled and secured with polysulfide sealant.3:13 The project also includes installing fiberglassed-in backing pads for a running backstay pad eye.0:43 While some installations utilize metal backing plates, the combination of a solid fiberglass layup, wood reinforcement, and correctly sized fender washers provides sufficient strength.3:13 The configuration allows for the future addition of a solent stay, which can be attached to a dedicated pad eye or stored aft against a shroud.3:40
