Also this is to be a OSO discussion and the outside interruption of any Uptight AZZ hats from Yacht Forums especially that F.A.G. Henny will not be tolerated

Well this was another presumption that was made that it was heavily damaged by the boat rocking back and forth on the bottom . What I am showing is how shoddily and underbuilt the tubes are.

Now if you look at the 3rd and 4th pics with the 4th also just an enlarged of the 3rd.This is the inside of the boat where the tubes come thru and notice there is no heavy tearing. Just a clean break of very little material.

To me it looks like maybe one or 2 layers at best.

A;lso you can see that the top of the tube went cleanly out thru the bottom . This shows that there was no other reinforcement on the top of the tube.

So what we are seeing is a tube that is approximately 12 inches tall with no upper support that is depended upon to support the forces of a rudder behind 90 thousands pounds of boat to be secured by 1 or 2 layers of glass.

IMHO it tangled with a submarine and lost. Kingspoint is not very far away everyone is playing in the waters there.

You are joking right?

There is no damage below the waterline what so ever other than the broken rudders stuffing box.

All damage is 2 feet above the waterline.

What I am trying to show is no forces did the one damage that is apparent underneath the waterline " The rudder stuffing box"

It simply failed because it was under engineered and than poorly constructed and supported inside the hull

I did a screen shot of the video that shows a full view of the rudder stuffing box both inside and outside.

You can see this because the outside transom and the molded inside cockpit that faces the transom is torn off and missing , but that is a whole other story.

What this screen capture shows is a fiberglass tube like i described in earlier posts that was simply lightly glassed into the inside of the boat with what appears no structure around the top inside to reinforce and support the top of the tube.

What you see in the photo is the rudder that sits in the top of a large tunnel that the prop is in to reduce draft. I suspect that because of the height of this tunnel and the depth of the cockpit floor there is very little room to allow a tall heavily supported rudder stuffing box.

So this design is what they ran with.

it didn't hit anything, it fell apart.

anyone have the link of that Powerplay in a race back in the day stuffing and the bow imploding ?

Great example when lightly built hulls tangle with big water.

I worked a bit for a custom Carolina manufacture and the way the rudder tubes were built and installed in their 40 knot boats was as I describe in the following.

It has been quite a few years but I believe the rudder shafts were 2 1/2 inch to 3 , very heavily built.

Than the tubes were secured inside at the base with a large fillet and than 6 or 7 layers of 18 oz biaxe extending as far out as 12 inches and 4 inches up the tube.

Than the tube outside on the bottom was glassed with multiple layers and faired in to the bottom of the hull.

Next the tubes extended up in side the aft bilge about 18 inches , They had this height to work with because their props and rudders are not up in a tunnel.The tops of these tubes ran through a 2 inch thick by 12 inch horizontal support that bridged the stringers , {picture a 2 by 12 maybe 10 feet long lying flat across the stringers with the tubes coming up through the top} This is called the rudder shelf and is the main support for the rudder tubes.This rudder shelf is heavily glassed in as is the tubes to the shelf .

All of this is done with secondary bonding but all surfaces are stringently ground and prepped with 36 grit and than laminated in with biaxe and West System epoxy.

Overkill. No not with a 60 thousand pound 65 footer running 40 knots with twin 1350 Cats in front of it.

Makes the installation you see in the pics in a 90ooo pound 57 Bertram seem a little weak doesn't it?
