What to do??? Need help BIG TIME!

[tlandauer]

I have this problem: the seam of the halves looks to me is not straight and i ALWAYS assumed that I should take the reading from the floor of the tunnel until i checked with a bubble level, the seam is actually level and the floor is slanted? How should i mount my rudder? perpendicular to the seam or the floor?
If i mount it perpendicular to the seam, the rudder won't look straight from the back.
The ride pads are very true, they touch at the same corners on the glass top.DSCN7324.jpg DSCN7325.jpg

If it were me, mounting perpendicular to the floor would be the only way to go. Looks as tho in your pic you have it marked out properly.

That is what I would like to do, but my head hurts just to figure out what is going on here. I have seen the brother of this hull ( Drifter S) , and it looks just like this, that's why I assumes the mold was slanted at the seam. The sponson seem to measure out equally, so does that mean the hull on the water theoretically is riding one side higher? I guess i worked too hard over the weekend, i can't think straight.

Yeah, mount it at a 90* angle to the bottom of the hull/floor

I think the seam is just playing tricks on you is all. if you really wanted to know you could simply put the hull back on your set up table in the pic and measure from the table to the different points on both sides of the hull. If the transom hardware concerns you, simply lay a square in the table and align it to center on the transom. If the hull is straight and true, this should be exactly perpendicular to the ride surface.

From your marks in your pictures tho, it appears your rite on track!!

Thanks for your input. Appreciate it.
I don't like to be a bother, but i measured it in a different way, the hull is not true in the sense that the floor is definitely one side higher than the other, please have another look at my pictures.DSCN7326.jpg

Port side is lower than starboard side. If the glass is the water, then ???
Sorry....

What hull?

[tlandauer]

H&M Intruder S, I guess I never thought this is possible, just assumed the seam is off, now what?

[tlandauer]

I wish I had checked before, lesson learned, this will never handle right , am I correct to predict as such?
Strange, I swear I saw similar characteristics on the H&M Drifter S once.

The seam looks level, so I'd mount it 90deg to that. All the intruder hulls ive seen have this same problem and ive not read anyting about it affecting the way it runs.

With the boat sitting on the table, I'd be squaring & measuring up off the table. Forget about the angle of the seam or the floor. You want the rudder perpendicular to the ride pads sitting on the table.
Well that's what I would do anyway.

Beat Oliver over the head with it but, that requires a plane trip. That's something I've never seen. How are the sponsons along the length, are they even on a setup board or are there other inconsistencies?
I just checked and there are no transom pictures on H&Ms site for any Intruder S.

Thank you both very much, it is the sensible thing to do, although visually DISTURBING!
I must inject a bit of self deprecating humor here: I am very near sighted and in one eye especially, so even with prescription glasses I don't see a straight like due to the high index of correction, my brain has learned to compensate for it most of the time, so when I realized this issues this morning, I thought my brain wasn't kicking in to do its thing.

The sponsons along the length seem OK, also all the angles in the step seem good. ( matching that is)
It is really strange but as Heath said, I too saw another H&M with similar charater in its seam.

And thanks again, you gave me the idea to measure from the table instead of just relying on the bubble level.
