Given the lengthy discussion on the plausability of an early Ski Sporter 16 hull with a modified Super Strangler achieving 84 mph...do you believe;

A) YES, I'm a believer!

B) NO, not even if it drove off Niagara Falls!

C) Maybe, because I have a short attention span and the thread was 600 posts...?

You may need to re-structure the poll as it's not operative.
But I'll answer anyway.......it's all about my attention span :cool:

I wasn't finished making it.... It is the first poll I've ever created... fun huh?

Woobs,

I like the poll, but I'm pretty sure that Ghost will be along shortly to explain that due to physics and that pesky law of gravity it isn't possible for the 16 to hit 84mph going off of Niagara Falls, 7k rpm 300x motor or not.

It's only a 167 foot drop. Boat would probably be going in the upper 60s when it whacked the bottom. My TI-85 says 68.4mph, but I don't know the exact cd of a 16 in free-fall so I had to swag it a little.

That said, I'm sticking with my original answer (B). :popcorn:

I could have said... "even going off Niagara falls with a six pack of JATO assist rockets at full glare mounted on the aft deck". But, I didn't want to break any new ground in the technical performance area. :)

or just... NO.

But, what fun is that?

Lots of unknowns too about going over the falls. Like, is the boat moving forward under power when it goes over the edge? If so, will it start out kinda flat before the stern ends up leading the way? And if that's the case, maybe wind resistance might slow down the rate of acceleration.......
Maybe we should get someone to volunteer their 16 and see what happens! :)

Classic! I did all the metric conversions approximately but still got 68.3, so I'm thinking we're in the ballpark. And as you imply, that would be in a vacuum. I suspect it would rotate a bit toward stern-first and of course, be slower than that.

Or the incomparable Super Strangler and the 70s prop bite right into the air, and it just flies away.

the water coming off the falls would beat the boat to the bottom....

at whatever speed that was :nilly:

Based on wind resistance, for example, the terminal velocity of a skydiver (http://www.donzi.net/wiki/Skydiving) in a belly-to-earth (i.e., face down) free-fall (http://www.donzi.net/wiki/Free-fall) position is about 195 km/h (http://www.donzi.net/wiki/Km/h) (122 mph (http://www.donzi.net/wiki/Miles_per_hour) or 54 m/s (http://www.donzi.net/wiki/M/s)).[2] (http://www.donzi.net/forums/#cite_note-Huang_1999-2) This velocity is the asymptotic (http://www.donzi.net/wiki/Asymptote) limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the terminal velocity is approached. In this example, a speed of 50% of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on.

Higher speeds can be attained if the skydiver pulls in his or her limbs (see also freeflying (http://www.donzi.net/wiki/Freeflying)). In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s),[2] (http://www.donzi.net/forums/#cite_note-Huang_1999-2) which is almost the terminal velocity of the Peregrine Falcon (http://www.donzi.net/wiki/Peregrine_Falcon) diving down on its prey.[3] (http://www.donzi.net/forums/#cite_note-3) The same terminal velocity is reached for a typical .30-06 (http://www.donzi.net/wiki/.30-06_Springfield) bullet dropping downwards—when it is returning to earth having been fired upwards, or dropped from a tower—according to a 1920 U.S. Army Ordnance study.[4] (http://www.donzi.net/forums/#cite_note-4)
Competition speed skydivers fly in the head down position and reach even higher speeds. The current world record is 1,357.6km/h (843.6mph/Mach 1.25) by Felix Baumgartner (http://www.donzi.net/wiki/Felix_Baumgartner) who skydived from 38,969.4m (127,852.4ft) above earth on 14 October 2012. The record was set due to the high altitude where the lesser density of the atmosphere decreased drag. [5] (http://www.donzi.net/forums/#cite_note-5)

I think the boat hits the bottom at the same time as the water

Not enough data. Need to know the exact prop pitch, x-dimension, strake length, and paint code of the 16 to be able to jethro it out.

I'm just wondering if I have this right. This engine is 99 CID or about 1.6L. Four cylinders. 1960s technologies. No forced induction or N2O. No way will this engine push a V hull to 84. Not even a mod vp; Maybe a little tunnel hull like an STV but not a v with a round keel. I hate to call anyone out but I had to vote no. Maybe over the falls though...Yes, I've been following the other thread loosely.

Taking all that into consideration what role does the Maid of the Mist play in all this? If the boat lands on the superstructure then it has fallen only 152 feet. However if placed inside of a wooden barrel and running a 28" pitch stainless lab worked prop I suspect that if my numbers are correct it would hit 83.67 at 152 feet or 91.77 water to water. The only outstanding numbers to be plugged in are the lower unit gear ratio and what type of music is being played at the moment of free fall. Maybe Tom Petty's "Free Fallin"?
