it has always been my understanding that Cigarette produced quite a few kevlar layups in the Top Guns and Cafe's, whereas there were only a few actual Carbon Fiber layups........namely the 4 Top Gun F2's.

maybe CB could provide the "real" answer.

Philly quoted me a speed of 79-80mph freshwater, 80-81mph saltwater for a '97 Top Gun, Kevlar layup, covergirl cabin, Mercury 600SC's and Bravo1's.

If you give it the juice they'll stop bouncing!

TRS might ride a little more balanced but wait till they break or you try selling the boat.:eek:

The TRS will last longer then the Bravo. My Heavy 38 Flat deck has been pushed by 550h.p. motors since 1985 and only blew 1 drive. (knock on wood) When is the last time you saw that from a bravo.
My next boat will have 3's or larger before I go with a Bravo.
Just my $.02

Havasu Cig,
Good to know! :)

I owned a TS 35 for a couple years and have ran with lot's of TS 38, I have never seen a Cig TS porpoise!

The T/S Cigarette won't porpose. I've even tried, no dice. It rides perfect.

We had a 1994 Top Gun with 600 Hawks and consistently saw 78 mph in freshwater... :cool:

Below are some property values for the three materials. Keep in mind these values are at optimum resin ratios.

Modulus of elasticity(stiffness)
Glass: 2,600,000psi
Kevlar: 3,100,000psi
Carbon: 8,700,000psi

You can see how much stiffer Carbin is than the other two.

Here are ultimate strengths for bi-directional woven fabrics:

Glass: 25,000psi
Kevlar: 51,900psi
Carbon: 87,900psi

Now, here's how they compare in terms of weight:
Glass: 0.072 lb/in^3
Kevlar: 0.061 lb/in^3
Carbon: 0.054 lb/in^3

Here are the strength to weight ratios:
Glass: 333,333
Kevlar: 850,819
Carbon: 1,627,777

You can see that Kevlar is about 2.5 times as strong per pound of glass and Carbon is about 5 times as strong per pound.

Below is a chart illustrating the manner which each material behaves when loaded.

The fiberglass is blue, Kevlar is magenta and carbon is yellow.

Note how the glass and carbon reach their peak load and then simply fracture. The kevlar begins to go elastic early and develops load gradually; the initial stiffness(slope of the line) is greater than glass however.
