Might want a battery and some navigation lights, especially an anchor light... If you get hit while anchored out without an anchor light up, and you're NOT IN A DESIGNATED ANCHORAGE... you're screwed.
I have a nice solar/battery lantern that i raise with the main halyard. works really well as an anchor light. I use a bungee to pull the halyard toward the shroud and it keeps the lantern from hitting the mast.
There are a lot of good battery powered nav lights on the market. Remember: it's a small potter, i'm not going out for weeks at a time so the battery nav lights work great for overnight trips.
