chainplate [R07]: A metal fitting used in sailing vessels that connect the shrouds (side stays) to the hull of the boat.
Chainplates are easy to make out of strip brass or aluminum and are usually anchored along the hull by through-bolting, using a backing plate, with 2-56 x ¾-in brass or stainless-steel machine screws (with washers and corresponding nuts). For larger boats, 4-40 machine screws are advisable for greater holding power. The chainplate can be cut from 1/16- x 1-in brass or aluminum bar. Backing plates can be made from 1/8-in aviation grade plywood or a suitable hardwood. These will provide good support inside the hull.
These chainplates accommodate various types of turnbuckles and clevis/rigging coupler options.
