More on boat damage

[Squirtcha?]

Well finally got my lazy ass out and flipped the boat over today. Did some grinding to find the extent of the damage.
This is before grinding.

This is after.

By the time I got through all the bad glass (delam) it ended up going all the way through.

I threw a straight edge on it and found that it's way wavy and the whole area can be built up at least 1/4" on either side (not just the damaged side) so that'll be the plan. I'm going to go ahead and blueprint the entire bottom after fixing the delamination. Odds are the other side is in about the same shape so I'll do it while I've got it turned over.

I like your way of thinking :rollside: do it once and do it right! :)

Git 'er dun, Dan. Lookin good. :D

Dan, was the glass underneath your gas tank mounts delaminated as well?

[Squirtcha?]

Oddly enough the area under the tank hardware was o.k. I'm not sure if the clamping force of the hardware, through the tanks mounts, and the stringer washers held it together or what. I knocked it down anyway just to flatten the area and give it something solid and level to bond to.
I found that the area that delam'd had a layer that either didn't get resined, or the resin never kicked, or whatever. When I started knocking back the areas that were delam'd and just luckily never fell off, I found a sheet that was pure white and clearly had formed a layer that never bonded to the others. The fibers were still fiberous and like I said it was still white. It was right in the middle of the layup and that's about the area that fell off. Nearly 1/8" deep.
It looks like it's been like that since the day it was built and just luckily held together all this time.

Dan, glad things are working out OK !
and it may be for the best if your bottom was that uneven to begin with....
Time to set things straight and get the Hook Out !
Good Luck ! Happy Itchin'

Sounds like a warranty claim if you ask me. I would sue the builder and get all your money back for bad craftsmanship. Any boat that has problems after 20 years just wasnt built up to snuff. lol
Good luck with the repairs. As the others said, fix it right the first time.

Thanks fellas. It's actually closer to 30 years, but I'm gonna go ahead and lawyer up just in case. Ya never know. :rolleyes: Too bad I didn't get killed when it came apart. I bet I coulda won that case. :argue:
I blueprinted the bottom last year, but only the middle section. Fortunately it's still holding up well. Just a couple areas that I can touch up with some speedcoat (worn off from sand n such). Sure wish I'da noticed how flimsy the rest of it was. I coulda done all this last year.

Looking good Dan.
Whats the plan for mounting of the tanks?

[Squirtcha?]

Hey Pat. Same as last time. When I'm done building it back up it'll be double the thickness that it used to be. I don't reckon those tanks will bust loose then.
She'll be a heavier pig, but nice n solid. It'll never be a race boat so as long as it holds together that's all I really care about, and I'll be a happy dudeman.

no wonder u were so fast dan......paper thin light weight hull....... :) i am sure u will make it perfect.....just lots of hard work....... good luck with it

Looking at this pic, I have a couple questions. There are 4 strakes showing. 2 (outer) all the way to the transom, and 2 shorter (inner) ones that stop forward of the intake.
On my Hawaiian, the 2 shorter ones are straight (w/straightedge) from the area of the intake, to where the bottom starts to curve up to the bow. We'll say, for the sake of argument, 10 feet.
The outer 2, from the transom forward, are straight, from the transom, to about where the engine stringers end, give or take about 4 feet. Identical both sides. Then from that point forward, they are straight up to the same point as the inner pair, approximately. Now, if I put a long straightedge, on the outer pair, starting at the bow, and extending past the transom, at about 4 feet from the transom, it appears to start to pitch upwards. The straightedge is tight from the bow back to this point. At the transom, there is a 1/2 inch gap, tapering to zero 4 feet forward, then zero the rest of the way forward. Does this make sense? :rolleyes:
The point is- do I leave this alone? Or do I straighten the outer strakes while I am doing stringers, floor, etc?

[Squirtcha?]

I'm no expert but I'll take a stab at it. If I'm reading your question correctly, the only area that you're really concerned with is from the transom to 5' or 6' forward of it. Everything forward of that probably isn't in the water at speed anyway. If you look at the picture above, the area where I stopped my work isn't necessarily where the bottom got straight..........It's just past the point where it was worth being concerned about.
Make all your straight edge checks with one end of the straight edge hanging over the transom. The transom is your reference point.
Here's a couple other pictures (before and after). They were shot at slightly different angles but it's the same area (alongside the intake). You can see how the straight edge is hanging over the edge of the transom.

Here's a link to all the stuff I did on mine last year.
Bottom blueprinting (http://jetboat.homestead.com/Kidsriding.html)
This is actually a pre-blueprinted picture, but you can see that the area forward of the front seats (middle of the boat) isn't in the water (even before fixing the bottom).
