2. Inspect the Running Gear
Assuming there are no leaks, examine the running gear. Tilt up the outboard(s) or sterndrive(s) to check for cracked gear cases, bent skegs or mangled propellers. Don a mask and snorkel, and jump in to check inboard running gear, a pod drive or jet drive and its intake grate. In cooler climes, carry a point-of-view camera such as a GoPro with a waterproof case; put it on a pole that reaches under the boat, and play back the footage. Serious damage that leaves you dead in the water means a call to a towing service such as Sea Tow or TowBoatU.S. If the water's shallow enough, get the anchor down while you wait for help to arrive.
