Step number 1: Set up a signal fire.
Step 2: Sleep on the beach until the boat gets here.
Step 3: Frantically flag down the boat with any available materials…ie: neon yellow rain jacket.
Step 4: Desperately try to get an overloaded boat out over the breaking waves and safely into the open ocean.
Step 5: Leaving the bay. Note the fact that the boat was filled with water, the huge waves, and the fact that I sound reasonably scared.
