Good info for all. I now have a flashlight in hand while running at night. Not too long ago I was almost cut in half by a presumed drunk running on plane in a manatee zone, I heard one of the passengers shout "Man" as they went by. The operator never saw me, never slowed down, missed me by about 2', and my lights are 100%.
You cannot assume that if you're in a zone you're safe.
Now I watch 360 with flashlight in hand ready to signal.
Shark eyes are legal as long as they are mounted properly and have a Coast Guard approval stamped on them. Many times shark eyes are mounted right and face more downward and do not show proper vertical and horizontal sector due to the shape of the hull. The fold down light is also legal but when mounted it is unobstructed, be pefectly straight up and down, USCG approved, and at least 1 meter higher than the nav lights.
