it could spark and start a fire! :D
all the above
Automotive electrical parts are not designed for a marine environment. Saltwater is the number one culprit. However, boats are under load far more then autos. This produces even more demand on everything. Also, vibration and repeated impacts have negative results. Boats do not have a suspension system like autos.
yes! Distilled water is what you should use. Never use tap water.
maybe you will get electrocuted?
If anchoring, secure the anchor line to the bow of the vessel, never to the stern.
Electrocution, it's never fun
Water should never be used to fight an electrical fire. It could potentially cause an explosion or cause you to become electrocuted.
Trash, plastic, garbage, oil, gasoline, or hydraulic fluid.

It is probably a burst blood vessel. A burst blood vessel in the eye can be caused by coughing, laughing, vomiting, or anything that puts pressure on the eye/face itself. Staying up late will never be the cause. It should not hurt, should not impair your vision, and should clear up in about a week (if not, go see a doctor).

Any sacred vessel, relic or the like should be turned over to the local bishop where they can either be 'recycled' or 'deconsecrated.' Such items should never be subjected to desecration by tossing them in the trash.
