hull CRACK==> need input from fiberglass gurus...

[Ericfox]

Last night I’m prepping my ski for Daytona and lookie what I find (see below):

Questions:

1) why did this happen? My guesses are: gap between foam and glass in that area since that’s where they stuck in the exhaust tube… that + hits from rolling would do it…. Or water got in there and froze and cracked it… anyone see this before?

2) what do you guys do before painting fiberglass? Just sand? Or do you put on a skim coat of resin and then sand? Is it easy to sand it smooth without seeing fibers showing through?

3)I used some filler/epoxy, then about 3-4 layers of 12oz biaxial to fix the area…. I started with the filler to fill the crack… then a small 2-3” strip over the crack, then 2 large 7-8” pieces over the whole thing that go from the bottom all the way up into the side rail…. Some areas might have 4 layers since some overlapped on purpose… do you guys think this is enough to be strong enough again?

Can’t believe this happened…. Just glad I should have it fixed good for Daytona…

You don't need any fiberglass Gurus for this that should hold just fine,good job.

Man, all these newer SJ's I see falling apart. This is very concerning.

What you did is more than enough. I just wonder why it cracked right there. The others I have seen cracked farther up. It seems the botton decks on these are pretty chincey.

When are you going to be in Daytona? I will be there Friday and Saturday.

my '04 cracked right there but a little higher. I still need to fix.

 

[BruceSki]

the only thing i would suggest is to drill a small hole at the end of the crack to keep the crack from spreading any further.

other than that the fiberglass work looks good to me.



it seems like the 06's crack easier than any other year for some reason...
i think you are right mike w.... ive seen at least three threads on 06's cracking that havent even seen much abuse.

That should be PLENTY strong.

I wonder if the VIN plate drilled into the side in that spot had anything to do with that.

Dayum dude....that is worse than the dozens I have seen cracked in this forum.

But hey you are killin nice big rolls so I guess I should not be surprised.

That looks like it will hold though. Was it soaking wet in there?

I thought that was on the scupper side.

man thats some nice fiberglass ya used there........looks alot like the stuff reinforcing my square lol..........just talked eric on the phone and he was curious How do you prep and paint this>???? sand glass smooth>? then spray>?

 

[oldskoo]

I thought that was on the scupper side.

from the pic, it's obviously on the starboard (exhaust) side.

my new build is a 2006 hull, but first thing I did was fill those holes in and glass over - now it's painted and if I recall...mine were on the exhaust side as well..

hate to be the bearer of bad news but that glass will eventually peel off of there.
internal repair is the only way for it to last.

Duh...I can't believe I didn't see that.

I swear my old 96 hull had it above the scupper. And I think the law states rear left.

I wonder if Eric moved and hence the weakness and the crack?

 

[The Penguin]

I dunno. but mine was an unmolested (new) 2006 hull from FL that I bought without title/VIN from Virgin Waterworx. I had tough time figuring what those 2 holes were for until I held a VIN plate up there and they matched perfectly.

 

[oldskoo]

hummmmmmm any ideas on paint boys>???

On my '06 that is where the factory put the HIN.

There is at least 2-3 threads here with people with '06s with cracked hulls. I don't do rolls of BF's so hopefully mine will hold up OK.

On my 05' thats where the vins are.

Wow that sucks! Did you hit the bottom at edgewater? I did that with my sxr and broke off a chunk of gel coat. Maybe it was weakened and when the water in the foam froze it split it like that. Looks like its time for a trinity s/j hull.
