Kayaks and other small non-powered craft can be extremely difficult to see, especially when weather conditions are windy and the water choppy.
It is therefore recommended for kayakers to stay within 200 metres of the shore, where the speed limit for vessels is five knots. When crossing a channel, this should be done at a right angle to make the crossing the shortest possible distance.
Always be on the lookout for approaching vessels. Never assume an approaching vessel has seen you. Turn away quickly if a vessel is on a collision course.
The greatest aid to visibility is height and movement. Kayakers are encouraged to use brightly coloured or reflective blades, flags, lifejackets, clothing and headgear.
