    Default Keep an eye on these old boats!

    I had some cracking in the gelcoat job I did last year. I figured I just mixed a hot batch (too much catalyst) and it cracked from being too brittle.

    Nah! Look what I found under the crack. Same thing that happened to my Kachina a few years back, and almost in the same spot.

    All the white/yellowish (dead glass) has to come off and get re-glassed. I don't know if it would've come apart or not, but if it did...........it would've been a bad thing. Picture flying along at 80 or 90 mph and having that area come apart. This is a pretty light layup (450-500lbs) and not that thick especially right in that area. I'm guessing that by the time I clean up all that dead glass, it won't be more than 1/8" thick right there. It goes pretty deep.

    I think this is what took Southwind Sal's boat a year ago or so?

    Check your boats fellas.



    You can see where the white (dead) glass is spreading out on either side of the crack. Gotta get this off or the new glass won't stick worth a darn.





    Here's where my Kachina came apart. This one separated from underneath. Didn't even know it until I put it on the trailer moments after making several 85 mph passes. My kid noticed it and pointed it out. A piece about 6" wide and 1' long just peeled away. You can even see the mat where it peeled away a piece of the gelcoat on the transom. Basically took the strake out.

    my little texas tunnel de laminated on the passenger side by the motor and you can see through the bottom of the boat. i have my boat unrigged right now and will be doing all the glass work before it goes back together. i thought about it coming apart runnin over 100 it would blow the entire bottom of the boat out and could have been a bad accident waiting to happen.

    Yeah, it's kind of scary when you see the fiberglass delaminating. I always thought it was strange to see guys paint that area or cover it up with carpet when these problems have been talked about so many times. Myself, I want to know what is going on back there so I took the carpet out that was originally back there.

    Could be wrong, but I don't think this has anything to do with how much power is in it. Looks like it could be a couple different things causing it. Either when the boat was laid up originally they didn't get the glass to conform to this area and it had air pockets in it (personally I'd go with that one). The other side doesn't have as deep a corner to go around (more gradual where they formed the strake) so maybe that's why it's not coming apart over there. Or maybe the boat took a shot in that spot where it's coming apart. Although there is no evidence of this looking up at the bottom.

    Anyway I've almost got it fixed. Ground away all the dead glass. Filled the deep holes with chopped glass and resin just to occupy the space and level it out, then glassed 3 layers of 1.5 oz mat over that in progressively widened strips. The finished repair is about 3' long and 6" wide. Has good adhesion and should oughta hold o.k. Hitting it with an orbital sander to blend it in to the existing glass. I'll fill the pin holes with some Durglas and sand her smooth. Fresh coat of gel and should be good to go.

    Oddly enough it was the crack in the gelcoat that tipped me off to this. Carpet........that would be another deal. Probably never would've seen it then.

    Nah. The Cheena is gone. Sold it about a month ago. Actually I should say Joey TX-19 sold it. The guy that bought it won't have to worry about this happening. That thing is solid. Might've gone a little overboard (pun intended) on that one. I wanted to make darned sure it was never gonna come apart again and I'm pretty confident it won't.

    Got er done. Not perfect, but it matches the rest of the boat . Gelcoat is still wet and I missed a couple pin holes. Took most the day, but I can put the motor in tomorrow.
