Installing Raised Pads for Chain Plates

Chain plate pads ready for slots

The forecast for this week is hot and dry. Of course it is hotter than I like, but I’ll take this chance to install the raised pads for the chain plates. First slots must be cut in the pad to accommodate the chain plate. The slot is made bigger than the chain plate to allow it to move as the boat and rigging flex under load. A small amount of sealant will provide a water tight seal. The parts are clamped in the work stand.

Holes are drilled at the extremities of the slot

Holes are drilled at both ends of the slots.

Slot completed with Dremel tool.

The Dremel tool with a diamond cutting blade makes easy work of connecting the holes, making the rough slot. The slot is finished with a small sanding drum in the Dremel.

Chain Plate is temporarily bolted in place and deck hole trimmed for proper fit.

Forward Port side chain plate is bolted into position and the deck clearance hole trimmed as required. The chain plate must be bolted in, deck marked, then removed for trimming the hole. A couple times will insure a proper fit.

Trial fit of raised pad

Now the pad is placed over the chain plate to check fit. Deck is marked for routing a recess to accommodate the pad for a flush fit.

Routing the deck to accommodate the pad was very time consuming using the Dremel tool, but it could and was done. In the last picture we see the finished product, a raised pad bonded to the hull ready to accept the chain plate, sealant and decorative cover. Although difficult and time consuming, this modification will go a long way toward keeping the chain plate knees and bulkheads dry, thereby increasing the longevity of the new chain plates. I am happy with the result. I have restored confidence in the rigging for offshore sailing providing the hounds and fittings above pass inspection of my critical eye.
