My first video is an attempt to show that  NH's locally-endangered Loon has a primary enemy, and that is the powerboat—even at relatively slow speeds.
 
https://www.youtube.com/watch?v=SRZEliChKAw
 
In viewing the Loon video, I found out why I could most easily see the Loon.
 
The video has to be viewed in "Full Screen", then look for these clues:

After a dive, the Loon had returned to the surface for only a few seconds before being imperiled by the one boat in this fairly large area.
 
So what are the odds against New Hampshire's Loon species on weekends, with ocean-racers violating New Hampshire's speed laws?

Take 22 seconds to view Winnipesaukee's even deadlier threat to surfacing Loons:

He is probably doing 35 MPH. What do you expect him to do? 10 MPH?

I don't think that pontoon boat is tubing at as much as 35-MPH; however, he is potentially doing much less killing of Loons than this guy in the same area:

If they visit this topic they will have to watch and listen to the video. It is on automatic play. Very Happy 

I wonder how fast that GFBL boat was going?

That boat was going well over the speed limit. I estimate around 70 MPH.

He first came into view at about 55—opened it up to about 70—then you can see (and hear) that he backs off near the end of the video.

Was "the show" for me?

scratch

The point being—while he doesn't recognize it—he's a Loon-shredding machine, and is crossing surfacing Loon paths at the rate of one mile per minute.

I hope you send this video to the NHMP. 70 MPH in that area is very dangerous.

I don't know why. After 11-AM, the NHMP surely sees these scofflaws all the time; besides, they only come by in the late afternoon, when this area has cleared of weekenders. Ask WHL about NHMP "attention" to our high-density traffic and rafters.
 
This particular speedboat is actually kind of a routine "drive-by". I just happened to have a camera handy when I heard him increase speed from open water. Notice how the lake returns to quiet as he goes away.

He slows, but completes his "run" at 22-seconds—the end of the video. That's directly at Winnipesaukee Way (Road), at the development known as Port Wedeln.

At 3 seconds into the video, he crosses Keewaydin Point in the distance—so we have a "run" of 19 seconds that—according to my chart—covers exactly one mile. So, he must have been going about 180-MPH—right?

1.0 mile in 19 seconds = (1.0*3.15789) = 3.15789 miles per minute
times 60 = 189.4736 miles per hour.

You gave us 1 mile in 19 sec's, so I used those figures.

I assumed you accounted for any displacement or difference in the position of the GFBL vessel viewed along two different lines of sight.

Didn't you? Shocked

I went back to page 1, to find what I wrote—and it was, that I was Math-challenged.
 
Reviewing the video again, he chops the throttles about two seconds later than my previous observation, so his calculated speed would be even much greater than you've calculated—unlikely, of course.
 
However, he is about 1/3rd across the water from my shoreline—about 2/3rds from the opposite shore—roughly parallel to the near-shoreline. Had he been along the opposite shore, calculations could be far more accurate.
 
As I see it, there's no good way to determine speed through calculations from this video.

40 - 45 tops.. and APS he never "got air"... stop drawing unsubstantiated conclusions to try to make a point to further your agenda.

BTW: Please again provide a valid definition of "ocean racer". You seem to continue to skirt the question.

It's not easy to "get air" on such a small chop; however, if you view the video carefully, you'll see that the sharp wave is caused by his boat dropping back into the water.

I disagree completely. They are simply hitting a wake and not catching air. Trust me, when a boat catches air you would hear it from the sound the engine would have made. He never throttled back to compensate for the cavitation nor did you hear him zing the prop (slang for cavitating and not compenstating with the throttles)

So again your unsubstantiated conclusion is false.

Also:  Please again provide a valid definition of "ocean racer". You seem to continue to skirt the question. (6th time asking)
