Alex, when I look at boats on the hard they usually have the keel bulb supported, so most of the weight is on that support - and not stressing the hull.
Your shark is hanging in the air.
Can you please comment this. Is it temporarily until you get home or is that OK (the support looks well padded and wide).
I heard that the area around supports may be dented a little after winter (maybe it only applies to older boats).

P.S. BEAUTIFUL Boat!!
Thank you.

At the back end of the spi pole, it is simply attached to the shroud base, using the pole trigger itself, the front end of the pole I have a metal bracket, that has a hole in it, and that bracket is securely attached to the pit, and by coincidence the size of the pole is just perfect, for it to stay half way the life lines, perfectly horizontal.

One reason I don't like them in the deck is because there is allways an idiot kicking it, hurting my pole with his foot, (that by the way, was already there, minding its own business, way before the idiot moved to the front of the boat, and kicked it). Can't hurt the pole you know.

The second reason, I've allways attached my poles to the shroud, why??? So that when racing or in **** wether, we don't get the sleeping genoa sheet underneath the aft end of the pole, and then when you tack, it just rips the pole off, or breaks it. So in my boats the aft end is allways in the shroud. Can't go wrong with that can you?

I'll see if I have photos of the details of attachment.

Also if it is in the "air" and a wave gets by in the bow, there is no restriction for water evacuation.

Hello Tomaz, how is Europe? I miss home.

Tomaz, lets do some thinking here, shall we?

In reference to the "stress caused by the keel being suspended and not supported", when the boat is in the water, is the sea bed that supports it??

If the boat is floating, the stress is the same as if the boat is in the dry, isn't it? Yes it is!!

Now, the reason it is not supported on the bottom when dry, and suspended, is so that it does not stress!!! What???? yes!!!

If I supported the keel, it would be pushing upwards into the hull would it not?

Remeber my keel is not attached to the hull (well, it is but not as normal boats do), my keel is attached to an upside down box, inside the hull, and that box is surrounded by beams, logitudinal and lateral, that create a crib for the keel, and the keel is crossed by 2 studs along the lateral axis, and bolted with 3 bolts to the top of the box, so it is water tight and yet flexible enough to move sideways as we sail. My keel moves slightly, it is not fixed 100%.

The keel protrudes the hull into that box. So if I support the keel, the stress inside the hull, would be trying to rip the box and keel cradle from the inser skin of the hull inside. Makes sense?

If my boat is supported by the keel, the keel will want to enter the salon.

I may have to draw a sketch for you, if I can't explain it, but let me know.

So, for this reason, my boat is allways in a cradle when dry, so I don't stress the hull.

As far as the dents, or deformation, remember, my boat is Divinycell core, at a thickness of 30mm or more depending of the areas.

Its CF outside and Kevlar inside with very strong reinforcments in the keel area and along the sides, so it can sail in harder conditions, that cradle was made so that the supports are undernath the forward bulkhead, and rear bulkheads area.

Nothing was forgotten and all details have been well studied.

This boat could spend years on the dry and nothing would deform much. But again, this is no ordinary boat, it is MY boat...rememeber??eheheheheh

Answered your question?

Alex

Tomaz here is a simple drawing I made this morning that shows hoe my keel is attached, and it explains what I told you.

I am making another one that shows the insideof the keel box.

Here is the inside view of the box and the spacer.

The lid closes all with a special rubber gasket.



Please note that the structure WILL suport the boat 100%, I just avoid it, to make sure I don't stress it.

But this is one stiff arrangment, for sure. Will support a grounding at hi-speeds.

(before reading my post, please imagine me runing around in circles in panic!!!)

Ohhhhhhh NOOOOOOOOOOOOOOO!!!!!!!!!!!!!

I can't go sailing anymore.......thanks for the warning SA!!!!!!!!!

I must now sell my boat and end a life long sailing career....because of the poor design of my keel....

That's the end of it....damn....


SA that remark is like the ones I get from people here that say...oh that's not the boat for me....too much draft....

It enter my right ear at 100mph, and exits thru the left at 200mph

I would be most interested in the design characteristics behind the venturi equipped Portagee skull. I am somewhat familiar with the genus Northamericanus californius, otherwise know as the airhead. I can claim no similar knowledge of the Portugese jethead. Does the nozzle and venturi tube required for cranial evacuation require maintenance or adjustment? And, does blockage of the left ear result in a gastro-intestinal buildup of pressure? I thought all the gas was due to a diet rich in herring. What ever do you do during cabin pressurization of those trans-Atlantic flights? Another thought; can your wife hear the ocean when she puts her ear up next to yours?
