If I want to get 10′ of depth on a crank, I simply would run braid with a leader to the crank. Some distance from the boat will likely help to avoid having fish spook. If you want to run real small cranks at 10′, leadcore is an option. It is easy to fine tune with speed adjustments as well as it tracks the boat better than anything else.
If you really want to fish crankbaits nearly in the shadow of the boat, 3-way rigging them is an option. For me this is primarily reserved for small stick baits in current seams on the river where visibility is low and being on the spot is crucial.
