Which part of the hull is the keel? Looking to measure where my loader sits in relation to...just the lowest part of the hull down the centerline?

Yep.

Bottom of the vee in a vee hulled boat. When measuring for a loader us a yard stick or siimilar straight edge, sometimes the keel will be somewhat convex and it is easy to get an odd measurement.

Tunnels also have keels, some are flat and some are radiused.
