What if your boat runs a ground at high speed. What should you do FIRST?

Switch off the onboard engine, or lift the outboard motor clear of the water. Carefully check for hull damage that can cause leaks. Deal with any injuries by using first-aid, or phone emergency, if there are bad injuries. What follows next depends on the size and weight of your boat. What are you grounded on? Is it soft sand, pebbles, rocky shore? If sand, and your boat is not too large or weighty, it may be possible to push the boat back into the water from the bow. Or you could try rocking the boat to form a water filled hollow. Or you may need to phone for assistance!
