Has anybody conducted a census of the adult loon population this year? Maybe I'm just lucky, but it is a very rare weekend that I don't see and/or hear at least two or three of them.
And, not to be heretical, but they really don't seem to mind boat traffic all that much (except perhaps when they're nesting).
I've even seen them over by the Weirs in boat traffic that gave me a Maalox moment

, and in Meredith by the town docks during the antique boat show just to name a couple of busy times for boat traffic! They just sort of went about feeding with no apparent concern.
