    For your calculations; B is the Bearing surface, T the tensile areas, S the shear areas.

    The pin will be in double shear and usually you'd make the chainplate shear strength greater than the pin's.

    Look again, it has a spreader bar.
    remember that these are chainplates the stays will be angled towards top of mast and the fibres will be oriented in the same angles.
    A wide spreader bar and vertical lift would make the load path different to what the fiber angle is.

    Why would you assume that?
