Final answer:
In case of water flooding the boat, immediately identify and try to stop the leak, ensure all passengers wear life jackets, use a bilge pump if available, prepare to abandon ship if necessary, and call for emergency assistance.
Step-by-step explanation:
If water is flooding into the boat after running into some rocks, the first thing you should do is assess the situation quickly and take immediate action to prevent the boat from sinking. Begin by identifying the source of the water inflow and attempt to stop or slow the leak if possible, using any available materials like clothing or towels to plug the hole. Next, alert everyone on board to put on their life jackets if they haven't already done so.
If the boat is equipped with a bilge pump, start using it to remove water from inside the vessel. Should the situation escalate and it becomes clear that the boat is going to sink, prepare to abandon ship, ensuring everyone knows how to signal for help and stays together in the water. Always prioritize the safety of every person on board and call for emergency assistance as soon as possible.
