What should be the first action taken after running aground to ensure safety?

The first action taken after running aground should be to check for leaks. When a boat runs aground, it can sustain damage to the hull, which may result in water entering the vessel. Checking for leaks is crucial to assess whether the boat remains seaworthy and to evaluate the immediate safety of all onboard. If there is significant water entry, it is vital to take further action to prevent sinking, such as deploying pumps or signaling for assistance. Ensuring the boat’s integrity takes precedence over other actions that might not address safety concerns as directly or immediately.

While reversing the engine might seem like a logical next step, it could potentially worsen the situation by causing further damage or making it more difficult to assess the boat's condition. Shifting weight towards the impact point and attempting to untangle from any obstacles might be necessary later, but first ensuring that the vessel is not taking on water is paramount for safety.
