at night essentials:
-Head lamp
-flash light
-beanie
- xtra batteries
Along with the normal day time stuff
- PFD
- radio
- fishing crap
- etc.
My experience... keep the lights off... for me, it messes up my eye's natural night vision. Bring extra pre-tied rigs/set ups. Strap everything (paddle too) cause hard to see if you lose stuff in the dark.
Good luck and enjoy the at night adventure.
