I would advise reading a couple of books dedicated to boat emergency procedures. "The yachtsman's emergency handbook" is one, and "Emergency!" is another. I think the second one is out of print but it's great. It's very easy to find the relevant information, it's concise, and the hardcover glows in the dark.
a nice touch...
These books detail in words and drawings all the things you could try. Having read them ahead of time, you're ready to execute any number of these plans instead of trying to invent them on the spot in the emergency itself.
During my epic grounding incident I was able to try the following:
1. Hanging jerry jugs of fuel and water on a boom that was out to the side of the boat (didn't work).
2. Shifting crew from side to side, or fore and and aft (didn't work)
3. Powering in reverse and forward (didn't work)
4. bending several lines together and attaching them to a halyard which I attached to a kedge anchor which was perpendicular to the boat. (Worked really well!)
Another thing I did, which may really help on smaller boats, is to immediately turn on your fresh water taps. Each tap at 2.5GPM empties 20LBS/minute while you're doing the above actions.
