I know this is an older topic but I thought I would throw this out there: This is a GREAT TOPIC! It's winter and I'm not getting out much right now so I started looking around and found this thread.
KATABATIC: you make some great points and I agree.
mkrabach: I like you webpage. Pretty cool stuff.
I think paddle craft should use the red/green navigation color scheme. I use a system from Illumarine, www.headtoboat.com.
Its an all-in-one headlamp and kayak light system. they sell reflective tape too. pretty cool and not too expensive for the complete system. They were at cinci paddlefest last year.
