Also take ashore fishing equipment such as rods, reels, and tackle boxes. Any other personal items such as legal papers should not be left aboard. Disconnect any shore power lines but leave the boat's battery connection attached. These batteries should be fully charged. You will want this to provide the bilge pump with power.
Disconnect fuel valves to help reduce the risk of fire or water pollution.
One final word of advice is to get off the boat when the storm gets close. Staying on board is much too dangerous. Once the storm hits, you should stay off the boat and let things take their course. If you have taken the proper precautions, things should work out well. Once the storm is over, it is time to check your boat out.
