I've always considered initial or primary stability to be the tendency
of the boat to stay still when you first get in. for example a dock has
lots of primary stability.
Secondary stability is a boats resistance to tipping over. Consider a
boat which simply has a triangular profile, with a flat deck. The boat
will have negligible primary stability, trying to stay upright on the
pointed bottom. But have a lot of secondary stability. Once it falls over
onto one of the sides, it won't tip anymore.
Keep in mind that a boat with a lot of primary stability will stay parallel
to the surface of the water. Which is great when the water is flat and
exciting if you are paddling with beam seas (broadside waves).
