If the catenary disappears you need to let out more chain.

The producers of distant shores actually just filmed part two of their anchoring episodes last week where they experiment with catenary.

The short version is that the catenary leverage factor is half your scope ratio. Although scope ratios greater than 7:1 have diminishing returns with respect to the rodes's angle the catenary forces are increased dramatically.

Fortress Anchor's available greater shank to fluke angle would increase fluke setting ability in accordance to any catenary offered by a chosen type of rode product or its provided scope offered. After all... increased catenary provided to rode attached to anchor is specifically for making better angle for anchor's flukes or plow to angularly dig into the bottom.

Could be said for anchoring: Angle of the dangle is directly proportional to hypotenuse of the square! - LOL
