I have a very small aperture through the bowsprit
to accept the anchor shank. Can't get most anchors through there, the shanks are too tall.
But the Spade has a three piece triangular shank that has is fairly low, if wide. I have seen other boats of similar sprit design that ended up with a Spade for the same reason.
But.........the upshot is that the Spade shank is relatively reinforced in the sideways direction. Never saw them make a point of it, but now that you bring up the bending thing............
