What do you call a collection of paddlers?

What do you call a collection of Sea Kayakers? Is it a gaggle? a flock? or just a big group?

Sometimes i get hooked in to helping where big groups are concerned, it is sometimes more of a herding experience than a coaching one is this good or bad? i used to think it was bad although the more i do it the more i enjoy it, different characters, strengths, wants and aspirations that need tended to. This type of guiding can be hard work, but also satisfying.
