I didn't see this one on the list so here goes. I guess it depends on how mechanical you are and how much you are able to do yourself.
A Boat US membership. It has towing available but the thing I use most (in the USA) is the tide table.
Have a Waterproof flashlight, and a good Spot light. The light I use most is a Luci Light, an inflatable, solar rechargeable LED light.
Heat (the dry type is best) because you are going to want to dry things out at some point. The electric ceramic heater does wonders but you have to have 110 VAC power for that.
A small tarp, 5 x 7 at least, to cover the forward hatch both for light and rain, and it will also cover the forward center window to allow both to be open when it rains.
Water purification is a very good idea, as many of the places up north have boil water notifications up.
If you are anchoring, chain is your friend, and a boat length is absolute minimum. Double would be good and more is better.
If you have hydraulic steering, I would recommend carrying some fluid for that.
Be sure you have capability of charging any electronic devices aboard with what ever connectors needed: USB, MicroUSB, Cig Plug, or 110 household plugs, grounded 3 prong on 2 prong only.
If you are going near the Canadian border, have PassPorts available, just in case.
