Zimbo, if there are lights ahead of you, you see everything.
Many, many years ago we did a 24 hour Windsurfer race in Narrabeen lake and I was AMAZED how much I could see with no light at 3am in the morning

Without a personal light your eyes adapt and as long as there are lights or the horizon ahead of you, you will see any objects in the water between you and the lights.
If you carry a light you will not see outside of the light beam as your eyes will adjust to the brighter light.
Just ask Dogman who specialises in surfing First point with an Eveready stuck on his head!


You up for it again Dogman?!


Disclaimer: It is dangerous if there are other water craft around. Duuh!
A red light at the back might not be a bad idea.
PS: If you get hit it WILL become illegal!
