This is a set of 2 one 7.5 inch and one 6.5 one set of hull mounts. Very lite weight but very strong.
Both are sharpened
The shorter of the 2 was mounted for mock-up, but both are never used on running a boat. It's great for a boater with one boat with multiple needs
The thinner of the 2 runs is 1 1/4 inch deeper than the other.
