carbon versus Kevlar
 

what are the major differences in a top gun layup of kevlar versus carbon fiber

did cig use carbon early on then switch to kevlar?

How much weight savings are these materials over the standard fiberglass layup?

I am beginning the quest for a Gun and would like a full cabin 3A boat with either carbon or kevlar layup

That means the bullet is for sale

I know pink (purple) flaming is out there but it is a TRS boat it may be of interest but Bullet has to go first

Otis311 is your buddy interested in my bullet?

I believe there were flatdecks built with kevlar in the 80s. The carbon fiber came out shortly after that on 6 carbon 70 cafes, 6 carbon 70 guns, and 5 specially built 6 man staggered, cabinless revolutions with flat decks built for racin. I have an article on the cafe carbon 70 and it claims carbon fibre is stronger than fg and kevlar, but the kevlar is lighter than the carbon., the carbon cafe weighed 300 or so pounds less than the fg version. Hope it helps

I may be wrong about this but I thought along time back there was a discussion about this and there were issues with the carbon being to brittle and cracking.

Here is a picture of a friends 93 TG, SSM 3A's, Competition Marine 1000's, fresh water, let me know if you are interested.

carbon 70
 

Had a 90 carbon 70 cafe racer. Boat was unbelievably solid. Sold it with 180 hours on it, not a flaw in the carbon anywhere. Had Hawk 525's in it, would do about 73 mph on lake lanier. Boat could get major air. The 04 rough rider I have definitely doesn't feel as rigid as the carbon cafe did.

This one would be promising. Last I heard it was in the $115K range:

Mine is the '99 Carbon Fiber factory race boat. It has some stress cracks on the deck but it was a former race boat although raced very little from what I understand. Also, from talking to a few different people in boat construction, part of the reason for the cracks on the deck (only the deck is carbon fiber) is due to the different contraction/expansion rates of the gel coat and carbon. These aren't your normal spider web stress cracks that are due to an impact either. Just a straight line crack where the gel has split. I'm sure it is a lighter layup too since it was a factory race boat. The hull doesn't have a stress crack whatsoever so the info I have received so far tends to ring true. It supposedly tips the scales just a little over 8000 lbs with an all PVC cover girl cabin. Haven't had it weighed yet so I can't swear to those numbers. But, it has run 78 in glass smooth fresh water with carbed 500's so it must be somewhat lighter than an all-glass Gun.:D

Oh, BTW, we had an STV laid up in CF back in the late 80's early 90's. 19 foot mod-vp boat weighed 425lbs before rigging. Roark claimed CF was lighter than both Kevlar and FG.
