STV RR Question's

[scrmn3]

One of the first questions asked when someone lists a boat for sale is what is the weight.
Does anyone know the answer to these questions?
What is the weight of the lightest STV River Rocket?
Who made the lightest STV RR?
Who ownes the lightest STV RR?

My RR weighs 450 lbs. :thumbsup:

The better question would be "What's the lightest STV rigged out". Don't matter if it weighed 100lbs out of the mold if you rig it heavy as hell. You'd be amazed at what extra gauges, heavy batteries, different mids. wire etc....makes. You can rack up a couple hundred pounds easy.

[crimson merc]

Jack made the lightest I believe, Boo. Cant remember what it weighted.

[scrmn3]

Justin
Was Boo lighter then Casper?

Scott what did your weigh rigged?

[crimson merc]

Justin
Was Boo lighter then Casper?

I wanna say so. Boo had the aim dash and mid bolted to the transom, all motor and casper had the gauges and a jackplate along with bottles. Again I think this is right, but probably have it wrong

[wtsjr66]

I spoke to Wally at Triad about a few different boats, he would say let me get the book out and see if we weighed that one. His method was to weigh the boat glassed together with the rub rail and seat. That being said,we have expert wheeler dealers in our area that can tell you the weight by looking at it from the road!!!

Scott what did your weigh rigged?

I dont remember exactly but I always had blue bottles, extra batteries, and alcohol washdown tank riddin wid me. It wasn't a feather weight but was a bit lighter than standard. It was a Carpenter Boat and I was told they didn't build them too heavy. Whose ROCKET you got?

[scrmn3]

Scott
Me and Mitch own the Carbon Fiber Teal RR with the drag bottom RBR had the boat built in 1994 by Summerford.

Thats one RARE boat!

Oh. Ya'll must have never brought it to "The Hill". From your avatar it looks a lot like Billy's Teal STV.

[scrmn3]

You own RBT STV RR Now?

[Scott Tharpe]

Dam just saw that pic. It looks shaweeeeeet.

[scrmn3]

It does look like Billy STV.
We did not have the boat rigged for The Hill last year but we will be there this year to give Billy a try.

[mach351]

Boo was 385 out of the mold, or so I was told by a pretty good source.

[scrmn3]

That has to be the lightest one.

[mach351]

Yes, but there's rumors that may change soon....

[wtsjr66]

Yeah, got it about a month ago.We got the swivel bracket gundrilled for the shift shaft and most of the powerhead components gathered up. Hope to do some testing soon weather permitting.

[wtsjr66]

I do believe those rumors are true...

[scrmn3]

You got a special boat, looking foward to some fun with yawl this year.

[scrmn3]

Yes, but there's rumors that may change soon....

Is it going to be Carbon Fiber?

[mach351]

The brochure I have shows several weights of summerford STV's

River Rocket Ski - 775lbs
River Rocket Comp - 750lbs
River Rocket Drag - 675lbs (1400lbs class)
River Rocket Drag - 550lbs (1200lbs class)

These are the standard weights per the brochure. Obviously lighter ones were made "special order" like yours. Any RR with the rare drag bottom (like yours) should be custom built to owners spec, and therefore very light.

[mach351]

Is it going to be Carbon Fiber?

Carbon Kevlar

[scrmn3]

Carbon Kevlar
That should be a Rocket, It should be unbeatable in 660'
Is FT building it?
Where will she be raced?

[mach351]

Yes, and there's at least one coming from north of the border that's supposedly already built, but no reports as to the weight

[mach351]

There were some light carpenter boats built too, and some real light carbon fiber pro comps back in the day - I think the rumor is ten or less - Alisoon Man had one.

[scrmn3]

It going to be fun to see these new STV's line up with the Carbon Allison Drags this year.

[RBT]

And the 1/4 masters, and the big cube motors........ or the big cube motors on one of these lightweight boats.

[mach351]

Other rumors have been floating around there might be a third contender in the CF craze, we'll have to see if it happens.

[scrmn3]

He going to have to change his name if he going to race the Pro Comp.:D

[mach351]

No he sold it long ago - said this past weekend he didn't know what he had LOL

[BRB]

i think back in the day there was a sprint deck and bottom built 376 went to texas i think........

[Da Bull]

That should be a Rocket, It should be unbeatable in 660'
Is FT building it?
Where will she be raced?




It needs to come on down to a DSRA race and try out Mathews CF Allison. If he wants to see if it`s truly "unbeatable" thats the only way.

Bull I was talking about the New STV Carbon Boat.
It would be a honer to line up next to Mathews boat he is in a class by his self.
I don't mind a butt wopping Bull. LOL
That Allison would be fun to watch up close leaving the line.

[RBT]

That Allison would be fun to watch up close leaving the line.

Awesome.... YES, Fun.... NO

[paul folks]

I know dirty daves white and blue rocket was low 900s rigged with a 12" 280 and gas no driver and I've watched him walk down the side of it I believe jeff dunn had it now... By the way how do the drag bottoms handle as river boats

Paul I would not use my RR for river or lake.
Race only!

[scrmn3]

Awesome.... YES, Fun.... NO

RBT I think you are right Awesome not fun

[mach351]

Dirty Dave's was 470

[paul folks]

What I thought randy was thinking 480 outof the mold... Soo drag bottom no good for a wknd warrior on the river thank u for the input...

Gotcha. I thought you was refering to maybe a bran new 100 per cent all carbon RR. I guess there has never been one of those. Preston Carpenters previous STV Mod-VP CF weighed in at 315lbs bare hull (that was the word anyhow) so one would think that if an all CF RR was built it should be less then that with the open cockpit. Same bottom, Less material in the deck. Maybe Nass boats will build one some day.

You are correct, That Allison of Mathew`s is stupid quick from the hole. I worked on the starting barge at several DSRA events and had the best seat in the house.


DB

[Scott Tharpe]

Awesome.... YES, Fun.... NO

I believe I received the same sensation when I had the honor of lining up against Boo the year he brought it to the "King of the Hill" and it wernt perdy. Jus wish I coulda tied a rope to the back of it so he could drag my boat down the track.

[RBT]

Ya, me too.
Rich S too, at the rumble... Great seat for an ugly show.

[Scott Tharpe]

I was having flashbacks of when I lined my 305 Z28 up against my buddies 87 Mustang GT. They just keep getting further away.

[Michael Dixon]

Boo weighed 824 ready to race. That was with my helmet and lifeline and prop in the boat. Was also on 24 volt trim. At the time I weighed 160. Which put it at 984 just for easy math. Lol

[Scott Tharpe]

Dam boy you gettin fat. Mus be all them chicken wings and buzz lights. How's Randy's rig coming.

[Michael Dixon]

Yeah put on a few pounds lately. Twelve ounces at the time. Should be putting engine in Randy's this week. Other than that she's done. They're wantin to use it in LA boat show so it'll be April before it comes home.

[MODVP22]

I moved on to Tall boys, 16 oz. How many people here are on a diet to get their total weight down for their rig?

[RBT]

Preston Carpenters previous STV Mod-VP CF weighed in at 315lbs bare hull (that was the word anyhow)


DB

I don't think it is near that light.

[YELLOWSS]

that is exactly what im on..... a diet to lighten the boat up.... bought a lighten mid, and the only thing left is me to lighten up...lol
15" mids suck, but who wants to be in that 12" class racing mathew.. not me..

[hullbilly24]

If you have an allison drag boat and want to run a 12inch mid, then progas is the perfect class. Mathew, in recent history, has not played in progas much (maybe a couple times in Barry's Dr-20). I've heard if they lighten progas a little, he would like to run a gas boat, but I don't think that is going to happen this year anyway. Mathew really likes his alky setup and progas is spec racing fuel only. So, you are probably safe and progas really needs boat count!

Your biggest concern in progas is going to be the few BIG Cubic Inch motors out there these days. However, drag motors with 12 inch mids have won a lot over the years.

Good luck!

[patchesII]

I've lined up against Matthew a couple times. It's like racing the Matrix. Lol

He's out on you a couple lengths before you even know your racing. Harry's blue Allison isn't much different

[SANTAFE]

I have been there also Eric. I know what you mean about the two boat lengths.
RBT, have you guys weighed Prestons boat? It's really a nice boat no matter what it weighs.
Looks like the big cube engines are the future around here. There will be at least two more this year that I know of. Two 3.4's and runors of a 3.8.

BTW some people just need to get over themselves!

[patchesII]

Preston told me what his boat weighed rigged but out of respect for the current owner I'll keep it to myself. It's not much different from what Dixon said his boat weighed

[SANTAFE]

I always loved that boat especially the color combo.

[RBT]

The scary day will be when a BIG bush or galenrude shows up on a lightweight boat.
Yes I know to the gram what it weighs. (guess the cats out of the bag)
The numbers on here are not right......

and a small driver, say 150lbs or less. of course his balls would have to weigh half of that. lol

[RBT]

Notice the trend, lots of carbon and 200+++++ pound drivers

[MODVP22]

Time to hit the tread mill ;):D

[RBT]

I am down to 185

[MODVP22]

I am down to 185

you're catching me

[wtsjr66]

I'm down to about 168,the local high performance gurus around here are telling my STV is a heavyweight! Spings right around the corner,if I'm gonna be competitive its carrots and celery for me...

[Scott Tharpe]

Notice the trend, lots of carbon and 200+++++ pound drivers

My original point exactly

[Chummy]

hope to see some of this light weight boat racing this year!!

[MODVP22]

hope to see some of this light weight boat racing this year!!

I'll second that

[Rayzor]

I'm not going to argue with you guys about your ultra-lightweight STVs and Mirages, but I'd sure like to see one hanging from a certified scale for my own eyes. I don't see how your guy's boats can be so much lighter than F1 and F2 boats? I know what my '95 Mirage Ski Racer/2.5/280/ROS weighed and I also know what my '08 carbon fiber Revolution SST120 boat weighs. Are you guy's hooked up to thousands of helium ballons when you're weighing them???

[FlatSleek]

One of the first questions asked when someone lists a boat for sale is what is the weight.

My RR weighs 450 lbs. :thumbsup:


Robbie

Robbie this thread has got me wondering at what point will these types of tunnel hulls be too light and become flighty and prone to blow over or will the right setup and trim overcome those tendencies? with enough $$$ and the super light high tech materials that are available a hull in the 200 lb range is probably not out of the question but I'm thinking with the new green motors such as the Opti's, Etech's, SHO's weighing in around 500 lbs trying to get it balanced and setup right would be tough to say the least. I love my oil spittin gas guzzling 2 strokes as much as the rest of you guys but we have to face the fact that the green motors are taking over slowly but shurely like they have in the motorcycles and jet skis. and the performance parts aren't too far off either, when the aftermarket companies see the demand they will make them. the 2.5 parts are going to be harder to get and more expensive but if the hulls do get down that light the heavy motors might not be an option.

They are a lot lighter......... and a lot less durable. They also do not have cell's in them.

[Riverman]

What did Rico's Rocket weigh when you scaled it at Jasper? Wasn't it 4-something?

[rhickox]

Gonna weigh mine on a certified scale soon. It's a 97 Carpenter boat and supposedly weighed 475 out the mold. I'm bout #170 right now. Gonna try and loose at least 5 more though..

[Rayzor]

My Revolution SST120 weighs 380 out of the mold (with cowl, canopy and sponson tips on it) and my SST120 motor weighs 275 complete, so again, how are you guys so much lighter fully rigged out than my SST120 fully rigged out? I call BS on these 800+ pound scale readings you guys are quoting.

[RBT]

OK, call it it doesn't matter.
BTW a 12" S3000 is lighter than your 2.0 steel sleeve motor.

[Rayzor]

I know it doesn't matter, I'm just saying that you guys are not correct because your bare hull (which has much more materials to build because of the center pod) can in no way weigh less than 300#s bare, and that's what it would take to get down to just over 800#s on a scale fully rigged out. So what is the exact weight of an S3000, complete.......do you even know, or are you just guessing that it's lighter than my SST120? If you are running a late model mid section and SSMIV lower (as it should), it will be heavier than my SST120 setup with the old style mid and SSMVI lower. I'll leave you guys alone on here, I just hear all these crazy numbers all the time and decided to call you guys out on it. Post the actual weights of every item that comprises your 800# rig to prove to me how you do it.

[RBT]

I know the EXACT weight of ever single piece in the boat.
The scales at ODBA are certified.

[patchesII]

Your weight for your hull and motor only add up to 655 lbs. There's not alot left after that to add alot of weight so why is 800 so hard to believe?

Steering 15 lbs
Trim pump 13 lbs
Fuel cell 8 lbs
Seat 8 lbs
Fuel pump/Filter 3 lbs
Foot pedal 3 lbs
Misc gauges/wiring 15 lbs

So you can see that you can get under 100 lbs easy with your rigging depending on battery

How are you rigging your boat so heavy that it comes in over 800 lbs:)

[fast120]

its ez to get lite if you use lots of titanum an carbon fiber an hybrid parts an just thinking lite when you put it all togeather!!!..but it an't cheep!!!

[StratosVT]

I can 100% confirm that the CF STV (formerly Preston's) will get to or below 800lbs ready to race minus driver. I watched him weigh it in 09. $1500 in batteries would push it to sub 800. Whether you believe it or not is doesn't matter to me. The guy's who own the boats and race against them know how much they weigh!

[MODVP22]

I know the EXACT weight of ever single piece in the boat.
The scales at ODBA are certified.

I'll atest to that. Rob is very thurough with everything he does. Tons of research, testing and calculating.

[RichS]

The late 12" mids are heavier than the earier ones. I think a sub 800# boat without driver isn't to far off with the pieces that are available. I do think a tunnel that is that light is going to be a REAL single purpose item. Besides, I subscribe;-D

[patchesII]

How much do the older ones weigh? I think my new style weighed 81 lbs with the exh plate, adapter, and wings. I'd have to go back and find everything I wrote down

I would like to find a worm gear center section in good shape but it seems like they're getting hard to find

[Rayzor]

Just to let you guys know, he and I PM'ed back and forth and it's all good.

[RichS]

My smooth back manual up/down with the arms, plate and tuner and trim and hoses I think was 93#. Thats with standard hardware and mounting bolts and I think the back of the Ally jack plate and before the hole saw and titanium...

[Rayzor]

My hydraulic up/down transom assembly is already mounted on my boat, but my old style midsection, tuner plate and SSMVI lower are still off and I can throw them on a scale if anyone is interested in the actual weight of these items. When I get my 2.0 powerhead back from Chris Fairchild I can throw that on the scale too! Steering wingplates made out of aluminum are no more than 2 pounds apiece, guaranteed. I just had mine powdercoated (along with my mid) and I can tell you they don't weigh hardly anything. With the minimum weight limit we have in SST120, lightening stuff doesn't help me at all, as being only 160 pounds, I've got to add 40 pounds anyways just to make weight!

[jay j]

Gonna weigh mine on a certified scale soon. It's a 97 Carpenter boat and supposedly weighed 475 out the mold. I'm bout #170 right now. Gonna try and loose at least 5 more though..

I know the guy that had that boat built he lives right here, and there were three built at the same time, and that boat is not that light. From what i recall it was 515, as my carpenter boat was built about 6 months later and it was heavy built, i ordered it that way. We will have new scales at Rucker in April so bring em on Friday and we will weigh them and certify it.

[patchesII]

Sounds like theres 10-12 lbs difference in the clamp swivel assembly according to what Rich posted. Thats the number I've heard before

[rhickox]

Thanks!!! I'm takin some rigging weight out of it right now and moving some weight different places... It is light enough for what I want to do though...And a great running boat from what i have seen so far...

[MODVP22]

They are a lot lighter......... and a lot less durable. They also do not have cell's in them.

Are saftey cell's that heavy? Any idea what they weigh?

[RBT]

Are saftey cell's that heavy? Any idea what they weigh?


~ 55 lbs

~ 55 lbs

Got a notification on this old thread. I really miss these days! So much was changing so fast in the Pro Drag class. Crazy how much lighter we got a few years later
