    16 o/b Super Strangler poll

    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.

    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).

    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!

    People said I was full of feces when I was radared over a 100 in my 16 40 yrs ago,
    so
    yes I am a believer, but then again I believe in Santa Clause

    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

    Based on wind resistance, for example, the terminal velocity of a
    skydiver in a belly-to-earth (i.e., face down) free-fall position is about 195 km/h (122 mph or 54 m/s).[2] This velocity is the asymptotic 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). In this case, the terminal velocity increases to about 320 km/h (200 mph or 90 m/s),[2] which is almost the terminal velocity of the Peregrine Falcon diving down on its prey.[3] The same terminal velocity is reached for a typical .30-06 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]
    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 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]

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