: the skipper knows them. Photons don't prevent collision. The paddlers were
: carrying all manner of little LED headlights and 2AA ACR incandescent
: lights. The were not adequately illuminated. LED lights like the tek-tites
: are visible and more effective than the common 2D cell nav lights used on
: dinghies. Having adequate running lights provides a CONSTANT source of
: information for other boats to prevent collision. Turning on your
: "torch" "in time" to prevent collision reflects the
: available technology when colregs were developed. LED lights provide more
: lumen output and allow conventional running lights on small craft. In
: close quarters random illumination with a directional "torch"
: that ISN"T meant to be shined at the colliding boat doesn't provide
: adequate time given that the paddlers hands are occupied.

: If one was to use a "torch in time to prevent collision" I'd go for
: a BRIGHT light, something 3watts and above, shining along the foredeck
: which is just as likely to mess up the paddlers night vision. This is a
: good one: http://www.uwkinetics.com/product/9

Running lights that can be seen make sense, unless it's dead calm conditions the running lights 6" or less out of the water will never be seen. A 12" wavelet will obscure the lights completely. In conditions that you need to be seen they are generally worthless on a kayak. If it makes you feel better, do it, but carry a light that can be seen for safety.
