Gary is correct - if your boat is powered by either gas or electric motor then you must register it.
The launch permit applies to unpowered boats.
PFD is essential. I always have mine on.
Also, if you plan on fishing at night, you must have a single white light that is visible from all directions.
Some guys think that a headlamp will suffice, but that is not the case, especially if they don't have it on all the time.
On my one man pontoon boat, I use a solar landscape light on a plastic stem from my yard that I stick into one of my gear bags and it works like a charm. It does not cast light into the water, can be seen from a good distance, and it requires no batteries.
