will it take off?

This isn't going to develop into a salt-water/fresh-water issue is it? How about the affects of suspended particulates in the water? Abrasion on the hulls eventually leading to complete failure of the floats?

So many variables, so little time...

Well if we are going to complicate things (and get this thread over a thousand posts) we'll have to introduce a discussion of ground affect and how the moving water underneath the plane will increase the ground affect.

Just how will the moving water increase the ground effect? Ground effect is mostly a function of the span, chord, height above surface, and air speed of the relative wind. There is little or no wind speed as the coupling between the moving water and the air above it is slight. The higher you go above the water-air interface the less the effect on wind speed. Virtually all float planes and flying boats are high wing which maximizes the distance above the water for the wing and minimizes the effect, in this case, of moving air and any ground effect.

Sorry, no Pantella.

Silly me, I assumed you wouldn't want to startle the fish any more, the ones that weren't run through the magic prop and were already nearly at max nervousness. So you just drop, or lower the anchor. Of course if you toss it out in a parabolic trajectory starting with a finite upward vertical component there will be an oscillation of the level of the pond but the central tendency will be as I previously described and of course the final result will not change assuming the anchor ends up in the water.

I overlooked the case where the anchor is tossed onto the shore and that will result in the water going down even more by the volume of water that the anchor would have displaced had it gone into the water.

Nope. The water will go down by the amount of water needed to -equal the weight (mass) of the anchor-. That is more than the amount of water it would displace. Assuming of course that the anchor is heavier than water.

Assuming the usual, anchor is heavier than water, it isn't spread out so thin surface tension will hold it up, gravity isn't repealed in that very small patch, volcano doesn't suddenly blow a blast of water straight up...

Will we reach 1,000? Stay tuned.

Good call Harry, I let my fingers outrun my brain, again and that doesn't mean my fingers are fast!

What you said is what I meant, I think... probably.

I'm distracted... my monitor had a horizontal oscillator failure and all I had was a vertical line in the middle of the screen so I ripped off my wife's monitor. I have to pan around as my whole desktop is larger than here display space. The viewing area thingy isn't the "excuse: for my misspeaking, it is my overwrought mental state at having to research a bunch of sellers and picking a monitor. I think there are too many choices!

Maybe I could trow my monitor in the pond and see what the level did. No, I guess not.. Eddie isn't into polution either.

Magic pond water? Yall still here? :d

Ok that's 966.

 

[Egon]

The water goes down, the water goes up, there is mass, there is volume, even a tidal effect should be taken into account, the wind may be blowing and there may be an effect from barometric pressure. And while all this is happening an unseen beaver has swam underwater across the pond and exited on the other side for dinner!

Worst of all maybe Eddies had enough and broken out the 12 bore!

I don't think we need magic water. Standard water will hold up to the low speeds required to make enough drag to counter the thrust of any production recip seaplane.

The Lake Amphibian is a geared down 3 blade pusher optimized for low speed power to make safe takeoffs and is not a speed demon by any stretch of the imagination. It isn't the most fuel efficient because of that. On a trip from San Diego to the Bahamas to go cove hopping with scuba gear it had to be set down frequently for fuel.

While a shot gun will take out a beaver, traps never sleep.

It might not be the beaver that Eddie wants to take out.
