someone correct me if i am wrong but...
deadrise is measured at the transom and I reckon anything above about 22deg is deep vee, although each manufacture has a different opinion to what a deep vee is.
A planing wedge is like the vee with the bottom cut off so there is a flat pad to create extra lift. Makes ya boat go quicker, but I would imagine it makes it a little less grippy in the turns.
