Anyone have a tower on a 196?

Re: RE: Re: tower

Quinner, the ability to rock the boat was solely due to the narrow '80 hull. Assuming the tow points are the same height, the force from a skier would rock a boat with a tower just as much as an extended pylon- simple physics. The tower would probably spread out the force more evenly, making it a little easier on the deck/hull.

TRBenj,

Yes, narrow hull would rock more, but I'm not sure that I entirely agree with your
physics. When pulling to the side on an extended pylon, the entire rotational force is focused at a single point, where the pylon mounts to the hull. This could be a in the thousands pounds with a heavy skier pulling hard on what amounts to a 6 or 7 foot lever. With the tower, I believe the tower distributes some of the load, pushing some of the force to the side of the boat opposite the skier. At that attachment point, I believe the counterforce of the boat's own weight, is at it's maximum. ICBW, it's been 25 years since I studied physics. BKH

Brian/TRB,

I remember from Dynamics that the problem is solve easily if you assume the moment arm is a rigid structure, be it tower or pole. In that case it doesn't matter if it's built with toothpicks it exerts exactly the same force on the hulls runners counter acting the force of the boarder. That said a tower will likely flex less exerting more force on the runners instantaneously causing the boat to lean more, but the difference should still be negligible. It seems the problem is easily solved if you just break it down to the applied force and opposing forces.

Doesn't matter the path the force is translated, It's the same distance (lever arm) from the center of mass of the boat, both in theory would tip the same. I don't even want to go into center of bouyancy.

Mike,

I've made the same assumption when trying to calc the folce a boarder/skier might put on a tower, or extended pylon. But, that's mostly because I'm not smart enough any more to break down all those vectors, omegas, blah, blah, blah. You two are proobably right; the forces are probably the same, or close to the same. Yet, antidotally, it's always seemed to me that the boats rock over more with an extended pylon than with a tower. Maybe it's just wishful thinking. BKH

I agree, but can't figure it out. If anything the weight of the tower causing the CM to go up would make the tipping factor worse. Let's discuss this further over a couple drinks eh?

big words, physics, etc. Looks like the crowd is about 50/50 of me turning the best ski boat in the world into a wakeboard boat! My vote is to not do it, but for my kids, I just might. Let's see that will bring my retail price of an 07 196 to apx. $60k YIKES!!!!

Quinner, you in hibernation? Still recovering from GL? :razz:

What's up OTW?

I am still here, heading up to Michigan this afternoon for some skiing, all is good! I am looking forward to the Mini midwest Reunion, do it all over again!

Dave,
I would disagree that a tower makes a boat a wakeboard boat, I am primarily a skier and barefooter however I like to do everything else (trick, foil, board, etc.) as time allows. I always foot from my tower and ski from the low point on my extended pylon. You may want to consider the factory extended pylon as well, if nothing else it holds up the cover well.

OTW,

My company is headquartered in Skokie. I'll be in town for a three day meeting. Would be cool to get together for an adult beverage with Quinner, OTW, Hollywood, mojo, etc. BKH

RE: Re: RE: Re: RE: Re: tower

yea I know,

just making a reference to the movie "The Usual Suspects".

I am game, let me know what works for you.

[niagararob]

good movie ,"Usual Suspects" . Not enough skiing scenes only people falling into water dead.

[bkhallpass]

I'll have to rent it. BKH

Thanks cat for the pics. Looks pretty good for me. Man I hope I dont get sucked into the darkside.
