Be Seen with the 4 ft Kayak Safety Flag. When out on your kayak, you are very low to the water. Add to that any wave or swell action and you are often hidden from other boaters view. The 4 ft. tall safety flag will help other boaters see you. Very important in areas with mixed boating traffic! If you have internal access to your boat through a hatch, you do not need any additional mounting accessories. If you do not have access to the interior of your boat, you will need the deluxe mount bracket, sold separately.
