You have run aground. Your boat draws 6 feet when upright.
You think you can heel your boat 10 degrees by kedging with an anchor.
How much is is this going to reduce your draft?

Now, your toerail is underwater at 30 degrees of heel.
What will your draft be now?

For my boat, which draws 7'2" with a flat-bottomed keel that's about 18"
wide, heeling 10 degrees actually increases the draft by about a
quarter-inch (assuming that the boat does not rise or drop on account of the
heel angle).
