Oh and by the way when you cut and pasted your links above you should of left the entire paragraph in. What’s in bold is what you casually left out...here it is fully documented as you requested from your own source!! 
“Disturbance from sailboats and wind-surfing has not been documented, however anecdotal and behavioral evidence suggest a flapping sail can be perceived as a visual threat, and therefore has the potential to disrupt nesting and brooding activity, even in areas of high recreational use.”
“Believe it or not”...

Having summered many years in an area of relatively high Common Loon population, I recognize the short "threat-call" made by Loons. In most recent years, that abrupt call has been sounded for fireworks, Bald Eagles, and Ultralight aircraft. When that call is taken up by crows, you can be dead-certain there's a Bald Eagle overhead!

Jon Winslow: That doesn't mean that Loons are defenseless against Bald Eagle attacks!
While I welcome the return of the Bald Eagle, making all those "snapping sailboats" a threat to the nests of Loons is "
high-anecdotal evidence".
Has this "undocumented biologist" noticed the presence of boats that make artificially steep wakes for "lake surfing".

The common loon abandons lakes that fail to provide suitable nesting habitat due to shoreline development. It is endangered by personal water-craft and powerboats that may drown newly born chicks, wash eggs away, or swamp nests.[69]
