Kevlar Mistress?

[bustedbrick]

The seller and the surveryor told me that my 1985 Mistress has a Kevlar hull? Boat is a 1985. Does this make any sense? Is there a non-destructive way to tell if it is and does it really matter or change the way I'd do fiberglass work on it? Thx, Randy

Kevlar is yellow. you should be able to see that right thru the resin.

Sometimes it is difficult to tell just by the color but generally it will have a yellow/goldish look to it. easiest way is to hit it with a grinder and you'll know right away. Heres a thread i put up with a few pics.

what kind of repair do you need to do?

Thanks for the info and the link.

No hull repair needed at this time except for minor gelcoat repair. My question is pure curiosity. The surveyor didnt find any rot but that was doing his best with the engines in. Now with them and the drives out, I'll go over it with a fine tooth comb.

So did builders typically use all Kevlar in a Kevlar layup or alternate with regular glass?

Thx, Randy

On the last layer (the one you see inside the boat) you would see Kevlar, they would somtimes cover the seems with a strip of mat, but not cover the whole thing. and like stated in GD's other thread, if you touch it with a grinder you'll know right away because of the fuzz, regular glass cloth makes dust, Kevlar makes fuzz...

Great, thanks all for the help. This is a great forum.

Its my understanding that if you make 2 small grinds about a foot apart, that you can take an ohm meter and get a reading. Kevlar is supposed to conduct electricity. Ray
