There are no powerboats on my lake, but I always have two headlamps with me that I could use when on other lakes. Do you need different color lights for bow and stern? I also just started bringing a 10,000 lumen flashlight so I can get a better look at something if I want to. It works great.
I never really had the luxury of paddling after dark on trips. I didn't have the energy for it, and then you need to be able to find your campsite again. I'd like to do it on a base camp trip. The reason I've been going out so much lately is that my wife is out of town. She's been working in Ak since the spring so it's a good use of my time.
Calm and pretty, two good reason to do it, also the fishing can be about the best of the day.
