42 Fountain 500efi speeds
 

My bud is looking a 2000 42 fountain 500 efi staggered boat to take north to Ontario. He was told by the owner it runs high 70,s. With good props and a set of 1 in shortys he thinks he can get it in to the 80,s. That's a lot of boat to get in to the 80 s with 500 efi,s I think.

I believe 78-80 is the number roughly. 525s closer to 85. Very efficient hull.

You really need to take into consideration the real waterline length of a 42' fountain. Subract about 3' of swim platform and 1' of beak and you wind up with a 38' boat.

Nice boat. Should ride good but just slow.

:food-smiley-007::food-smiley-007::food-smiley-007::food-smiley-007:Uh oh...

Speed he quoted you is a fair # it is a staggered set up so 80 possible?But 75mph moe like it a guess:rolleyes:

74-76 is a realistic real # to expect, do a search in the fountain forum, there are plenty of examples ... He won't be disappointed in the ride I gaurentee it, & if he decided to up the hp down the road, this hull responds nicely :boat:

But who runs hard in poker runs anymore anyway! The last few I did everyone cruse at 55-65 mph

I did not know that fountain was the only boat that had an integraded swim plat form and I have 3 of them.

I think there are several on here who can only spew the same rhetoric every time anything is posted about fountain. They must have a program that emails them when a fountain post is created so they can bring up the swim platform. Lol

Yep :signs043:

haters will hate...lol

Its just another ignorant guy that owns a fishing boat, also a keyboard cowboy trying to get post count up.

I don't think anyone is hating. Physics is physics...the true running surface of a 42 fountain is not that of a true 42' boat. Less running surface means less drag. Add in the fact that 3-4' of the boat has no real weight (ie. beak and bustle)...and it's not hard to believe the speed numbers. it's not a dig at fountain, the hulls are efficient and the aforementioned reasons are part of the equation.

I think velocity tom trolled us :D

He practically begged for the obligatory fountain post :D

Thats about the dumbest statement I have herd. Maybe you Cig guys run your boats with tabs down dragging all of your haul in the water. And what do you consider "a true 42' boat"??? I know that when I am running fast. not much of my boat is in the water. But I guess you wouldn't know about that... you have a top gun

I don't care if the actual length of a 42 fountain is 11 running feet. It works! I ran
side by side from the shootout last year next to a 38 cig tg strait bottom with #6 drives.
my 42 ran equal, if not better that the gun. And let's not forget that boat can "crush 10 footers".
Hate on the beak all you want, the 42 flat works.

It's important to remember that Reggie Fountain didn't decide to include the swim platform in his length calculations. Every singe boat manufacturer was required to include the platform in the length per USCG regulations. So a Cig or anything else with a molded in platform includes the platform in the advertised length.

So a "true 42' boat" is what? Answer: It depends on if the swim platform is part of the mold.

I'm so sick of hearing this crap. Nuf said.

What does that have to do w/ anything? It's called a 42 Fountain!!!

I did what !!! Wtf all i did was ask a question !!!!!!!!!!!!!!!!!!!!.

They have to drag tabs or they will porpoise :whistle:

Yes physics is very dumb concept isn't it. Maybe it's best to compare a 42x to a 42 fountain. When sitting side by side in the water I am willing to bet the waterline on the cigarette is much larger than the fountain. Both because of weight, and actual true running surface (I.e. Not inclusive of a beak and bustle). Now if we assume 1/4 of the boats waterline is actually in the water at wide open that still means the cigarette has more boat in the water. Whether is 1' or 2.5' there is still more boat in the water thus more drag. Is it a huge reason why fountain boats are faster hulls?...no not the whole reason but part of it.

Remind me why this is a dumb concept?

yes a top gun from tip to end of hull, not inclusive of swim platform is 37' 6" I beleive. The swim platform would add another 1.5' or so.

In the case of my old 292 fastech, formula certainly uses the bustle as part of there measurement. I put a tape measure on it when ordering a trailer. From tip to end of hull it was about 27'. To the end of the swim platform aka bustle was 29'. I don't know if I beleive your Reggie story. The 38's and 42's look significantly shorter than true to length boats.

Your comments get more ignorant as you go...And physics has noting to do with your comments or your "now if we assume" theory. It only matters how a boat runs on plan, and how much drag it has. NOT how it sits not running... Maybe if you had more power in your Cig you would understand about less boat in the water.

I'm an aerospace engineer so no I have no idea what I'm talking about. So yes I'm ignorant, carry on.

And if you are disagreeing a 42x doesn't have more boat in the water than a 42 fountain at wide open...then you need your head examined.

No wonder why our space program it in the crapper.. & admitting to your ignorance is the only fact you have correct. And IF the "make believe 42X "your talking about is going slower then said 42 Fountain... then yes, it will have more boat in the water. What part of going faster makes more boat come out of the water don't you understand?

Sadly I understand more than you...you should probably re-read my above posts discussing weight and running surface. Putting equal power and drives on both boats 42x and 42 fountain will result in the fountain going faster. Why?

Because the running surface is shorter on a 42 fountain and because it weighs less. Which has been my point the whole time. But all the fountain owners get there panties in a bunch and instead of reading the comments for what they are...start making assumptions in there own head.

Boys, boys, boys, let's get one thing straight. No 42' boat has 42' of running surface actually in contact with the water. And every manufacturer has something of a tapered bow to both make sure the bow rise up and over waves and lessen the running surface. (Which of course reduces drag and increases speed.) But everybody has to measure their boats according to USCG regulations - as Fountain and everybody else does - or did. If the "Fountain beak" was such an advantage in professional offshore racing, more would have been done around rules that reduced that advantage.

And what of some of the last Fountain race hulls built with cut down hull sides that reduced freeboard and weight. The beak was pretty well gone and the stated lengths were indeed shorter. Oh, and they still won.

BTW, although it doesn't have a "beak" the bow on my Progression looks pretty sleek. That must (illegally) reduce the running surface and explain the speed it runs.

Yea my scarab is pointy too!! Guess it's a 29.
Compare the 42 stag fountain to even the avs38 and the 42 is a solid performer.
Rant over let the douche carry on.

No one is arguing the 42 isn't a good running boat cupcake. Again another instance where people don't read comments and insinuate things in there own head. Sad that you had to compare the 42 to a 38 scarab tho hahaha.

I was using your math space genius.

Right...

Can you please re-post this in the Fountain Forum.
These members can really derail a thread. :picard1:

WTF all I did was ask a question you guys need to go out side and shovel some snow. I just ran my 34 Phantom 93.6 mph with no ****n boat in the water!!!!!!!!!!!!!!
And I sell tools for a living and have set up more boats than both of yall put together !!

No shut the Fruck up!!!!

What tools? I owned a snap on franchise 12 years ago.

I was a snap on dealer for 13 years. Went independent in 2011. WFO since then.

OMG, so let's just come to the conclusion that a 42x cig is really a 44.5 boat when you include the swim platform (whether it's molded or not has no bearing on anything) Some manufacturers decided to mold the platform and some decided to add a bolt on platform. Yes they are labeled as the same length, but obviously a 42' boat with a built in platform is shorter than a 42' boat with an add on platform. Is there really anything to argue here?? Fountain is hardly the only boat with a molded in platform. I guess a 44MTI is really only a 40' boat too right?
Your cigarette is way heavier than a fountain, reducing performance but improving it's rough water ride. Hell if you want to get picky, let's compare a 42' fountain to a 38' top gun. The fountain is still lighter and has a more hydrodynamic hull design. Give Reggie credit where credit is due, he built some bad ass boats no matter how long they are or aren't!!
I don't hear any cig fans bashing Hustler's 388 slingshot as only being a 35-36' boat and thus comparisons aren't "fair"
Oh and one more thing, that Scarab 33 AVS with kick any cig's a$$ with the same power regardless of length.

Don't Hate on me.............. I love the cig's too, but let's have a reality check here!

No ones hating on fountain...just rationally explaining why a 42' boat can be that fast. Has to do with smaller than usual running surface and weight. not even sure why an argument broke out. Thought the fountain guys would agree. It's all physics based but the fountain guys don't think so...must be the pixy dust that Reggie puts in the hulls during the layup process

Doesnt seem like the beak, swim platform, or reduced running surface, caused this boat to have a hard time keeping up with 41 Apaches, or holding many race trophies. https://www.youtube.com/watch?v=kaYbNXMq7c8

So you dont think bottom design plays a role? Can you explain why my old 38 Fountain straight bottom was faster than a 31 Bullet with the same power, back in 1990? I can assure you the Bullet is not heavier, nor does it have nearly as much running surface. Matter of fact, the 38 Top Gun from that year wasnt much slower than the Cafe, or the bullet, with equal power.
