text: has anyone ever seen a shark while they were swimming in the ocean? or even boating? many times. windsurfing, kayaking, and even surfing.  they will even slide against you, it's a pretty terrifying thing, something you never forget. my scariest was paddling out and seeing a black tip, around 7 ft. i was shaking so hard i could hardly paddle. it just swam around me and went back out, but still, you realize, your in their territory.
