Tuff Boat on Long Island

[2.5-21]

How much does Dirk's weigh? What does Tuffjr boat weigh? I know the yellow hpdi boat was heavier than both.....

It's not a Unicorn is my point...Unless he's switching to a Scott-Attwater for power lol

Post the weights with pics of scales! you cant make a ball any more round only lighter!

No vacuum bagging, all infusion.

One can not infuse without a vacuum bag.

Hasn't Tuffjr been running a G2 all season? It's 1mph faster than the Hpdi from 12 years ago .

Interesting info coming out. DoctorC I like when you stick in some facts now and then.

So the early yellow 21' Tuff w/ HPDI 300 ran approx. 89 mph ? Was heavier (we talking say 150-200lbs?) then the Blue newer Carbon fiber W/G2 250 at now tickle 90 ?

I thought I recalled the yellow 21' w/300 hpdi had been to 92 but I now must be mistaken. I believe our local 2003 21' Red Intimidator once ran a 300 HPDI for a short time and that ran 92 with little setup time. Guess I confused the two.

My hat is off to my friend James Cole for his efforts in redoing this original (non-light weight, non-notched pad) 21' challenger and getting it to 90 with similar power.

when you infuse what pulls the resin in???
re carbon, you can make a boat too light (yet strong enough) but they wont work particularly vee bottoms
unless you have access to lightweight engine and everything else...

The blue G2 powered boat ran 94 according to the gps pic in his thread and the yellow (non-infused) boat ran 93 I believe. I don't know how much heavier or the weight difference between any of them to be honest...

1mph?
depends on what you ate for breakfast and how much hair you have
not to mention anything worth mentioning like air density

It's all relative....there are so many variables involved(set back, engines(mods), hull weight) that apples to apples does not apply. Driver skill and of course budgets come into play as well but I sure do love seeing what combos you N. Eastern V-21 boys run.

Oh, and the who's got the biggest "Prop" banter is amusing as well.

I come up with the same weight as mentioned before.

Gell 100#'s
Glass 400#'s
composite core 100#'s
resin 500#'s
seats 150#'s
rub rail 25#'s
fuel tank, hose, fits 75#'s

Total 1,350 #'s This will vary, and is a general est

I'm going to guess that the boat will weigh 1347lbs on the scale. That is with all rigging and jackplate plus the full interior installed but no gas in the tank. 1,347 pounds. I'm also going to guess that with the BRP G1 it will end up doing 91.6mph with half tank of gas (is the tank 60 gallons?) and just driver.

I love it when I'm right. I'm actually hoping it will weigh more than 1,347lbs because then Dirk will be annoyed with it an sell it to me after a year. The orange is kinda growing on me.

Your numbers are very accurate the only one that might vary with the build process (infusion) is the Resin

Lie detector!!!

Gelcoat is very heavy and is why I question the finish being paint!

Maybe Rob from Raybo can verify this?

Bingo 2.5. It all starts with the true total weight.

A lot of folks over the years have said that all the Tuff 21's are different custom layups. Tuff has been building this model for at least a full decade for general consumption and I'm sure that they have built at least (24) hulls in that time frame. Can Tuff 21 weights differ by more than 150-200lbs over two dozen hulls built? I tend to doubt it but I am not a boat builder. I think a bit of the speed that the Tuff's achieve are based on running in freshwater and zero humidity up North. I'm sure that there are folks on this board that can comment, but the combo of freshwater and no moist air is probably worth 3-4mph in top end. Now you are more apples to apples.

106mph 300XS Tuff in Canada is a 102mph Tuff in Long Island is a 100mph Tuff in Miami.

I don't know how tuff does it, but some infusion builders are painting right over the resin surface. No gell in the mold at all.
