Answer: Some items are indispensable for boating. Such as life jacket (1 for each person), fire extinguisher, circular float, whistle, flares, medicines, first aid supplies, nautical charts from where you are sailing, owner's manual, compass. No cases of night trips, light GPS, flashlights and clothing have your boat with navigation lights. Be sure to check anchor and hull conditions and never stop bringing fresh water to drink on board. Remember who navigates is exposed to the sun.
